# So What? Interpreting Customer Satisfaction Score Data

## Summary

In today's episode, I walk through how to interpret customer satisfaction score data, especially Net Promoter Scores, covering what they are, how to compute them in tools like Google Analytics 4, and what action steps to actually take with the results. Here's what this means for you. You gain a practical framework for collecting, analyzing, and using satisfaction data so it does not become another piece of dark data sitting on a shelf. You'll also learn these concepts: why the classic one-to-ten NPS scale is flawed and how a simplified three-option thumbs poll can work better, how Google Analytics can double as a lightweight survey collection tool through query parameters, and how to turn a satisfaction chart into a real action plan by following up with respondents and cross-correlating the scores with other business metrics.

## Full Transcript

Well, hey, howdy everyone. Welcome to So What, the Marketing Analytics and Insights Live Show. I feel like my voice went like way up for some reason, but uh I'm back to my normal speaking voice. Uh I'm Katie, joined by Chris and John. Definitely trying to uh stay focused today.

I don't know where I am. Um today's episode, we are talking about interpreting customer satisfaction score data, sometimes also called NPS scores. Chris, what is NPS stand for? Net Promoter Score. It is a methodology for calculating um well, yeah, I have a whole thing we can walk through on that, but uh I'll let you get the best the introduction first.

I thank you. I'm I I I'm definitely like my brain is ping-ponging today, so I apologize for that in advance. Uh so we'll be covering uh what customer satisfaction scores like NPS scores are, what the heck they are. This is a question I ask you all the time, Chris. Uh how to compute your own satisfaction scores with tools like Google Analytics 4 and what the heck to do with it.

That's the other question I ask you all the time. Is great, what do I do with this information? And so we'll be covering all of those pieces uh today. So Chris, let's start at the top. What is a customer satisfaction score?

What is an NPS score? Okay, so a customer satisfaction score is pretty simple. It's how satisfied your customers are. And there's so many ways to do that, right? You can ask people, you know, how did you like this thing?

Have you ever been to the like the airport or uh or some restaurants and stuff? There's like that little table, you can hit like the smiley face button or the frowny face button, you know, depending on how your visit was. There's there's all sorts of different ways to measure. One of the methodologies that is really well known in business is called the net promoter score or NPS. And NPS is a computation created.

I think it's Nielsen. I don't know. Don't quote me on that. I'd have to go look it up. But essentially, it asks people on a scale of one to ten, how satisfied are you with uh the thing.

Now, here's what's different. The the math that they use is kind of interesting. So on that scale of one to ten, anything below a six, they consider a detractor. These are people like, oh yeah, yeah, you know, it was okay, it's not great, or it sucked. Uh, I didn't like the sandwich or the cheeseburger or whatever.

Seven and eight are considered neutral, and then nine and ten are the promoters, people who are like, yeah, this is awesome. I'm gonna go tell a friend. Uh, I really enjoyed it. And so, what an NPS score does is it essentially takes the number of promoters minus the number of detractors, um, does a percentage basis and says that is your net promoter score. If you have, and the reason that their logic behind this is that you would think this should be or could be evenly balanced, but they're like, Yeah, mediocre is still bad, mediocre is still a detraction from uh from what's good, and so that's the sort of the basis of their their scoring comparison.

So that's what a net promoter score is a tabulation. In fact, there's there's even math for it on how to compute what those scores are. It's you know, it's the percent like versus percent unlikely. Um so it's just doing the percentages. The percent like is likely divided by total, percent unlikely divided by total.

So in the NPS world, it's promoters divided by the total minus the detractors divided by the total is your net promoter score. I asked about this in our free slack group this morning. So trust insights.ai slash analytics for marketers, and what our members thought of net promoter scores, and someone one of our members made the very astute comment that you know what I think is a seven, someone else is gonna think is a ten. And when I look at this range and how wide it is, I can see where this is problematic. Um, because you know, as someone who's done survey design, there's way too it's the scale is too broad.

There's too many options, and it needs to be so a typical Likert scale uh sometimes is a one to five, and so one being not at all, five being extremely, three being I'm neutral, and then two and four being the eh, I'm so so not, but I'm so so am. You know, that's a fairly straightforward liker scale. This scale, when I see this, there's too many options. There's you know, what is the difference between a three and a four? What is the difference between a seven and an eight?

Really nothing. It there really is nothing except in the back end mathematics, and so this is the problem with net promoter scores. And one of the criticisms of them is that they don't take into account how people behave. So at Trust Insights, we use a modified version of this, and you will see this in our newsletters and and on our website and stuff. Ours is like this.

Thumbs down, thumbs up, or don't care. And it's just three options. Um because if you look in the back end data, very often when people are doing scores, just like Amazon reviews. You get a one star, you get a five star. You don't get anything in between, right?

Again, there's always like that one guy's like, oh, I just have star because you know of this thing. I was like, yeah, okay, whatever. You have too much time on your hands. But for the most part, people are very thumbs up, thumbs down, or I don't care. And those to us seem to be the easiest way to simplify the mental load for people on responding to a survey.

John, what do you think of uh net promoter scores? Have you ever worked at a company where net promoter scores were, you know, a big measurement of success. Yeah, I mean I've gone so far too is you know companies that are actually tagging financial compensation and stuff like that to NPS. So it's yeah it's crazy the way it goes. I mean really you know this approach here is the same psychology behind the other scale really like when you look at the one to 10 scale the idea is that you're only looking at three possible votes.

It's yes I love you guys and I'm going to talk to other people or you know yellow is the seven eight where it's like it's okay but it's not enough to talk about and then yeah everybody below six has a problem right there's an issue there's something wrong. And so the the one to ten scale that's gives you some extra granularity by spreading out you do kind of figure out how pissed off people are because that's the one thing that's interesting. If somebody is you know even just willing to talk to their neighbor versus a fan that's out promoting you that's really just a plus like those are all just plus ones whereas somebody who's angry with you at a five or six is different from a person who's a two who could literally drive hundreds of customers away or drive you out of business. You know the the impact is negative in there. Um, and then the other thing with that's with all of this is that it depends on how you use it.

You know, if you're going to use it to generate more customer discussions and actually drive in to find out why you got bad scores or why you got good scores, it's great. If you're gonna run 5,000 surveys and just people are gonna stare at the number and have board meetings about it, then that's a system ripe for gaming. And you know, it it becomes a whole nother a whole different thing. Um, which is it's if you have no other um measurement stick, then that's great. Um, but you know, you can do better too if you want to.

It's just a matter of you know what you want to do with it and how much gaming you're willing to put up with around it if it gets big. It's like every Uber driver was saying, please give me a five-star review. Yeah, I feel like re I feel like online reviews is a whole different topic that we should cover at another time. Um we were actually debating the merits of those reviews this morning as well. But this is essentially, you know, a review system for a company or a service.

Um so that's right. What's next, Chris? What do we what do we need to know about NPS scores? Well, let's talk about what do you how do you how do you get this information? Because it is, it would seem like pretty straightforward, and yet it's something people struggle with.

So in the Trust Insights newsletter, every month we run this poll. It's the one-click poll. And our measurement, our data collection mechanism for this poll is Google Analytics, right? Because we want it to be something that's simple. We want it to be something where we can get at the data, and we want it to be something that it we can process and and other people could look at it if they wanted to, but we could certainly programmatically get at it.

And so what you'll notice is there's this poll, and there's three buttons, likely, neither likely or unlikely, and unlikely. And for next month's poll, I am adding emoji. Um, to be fair, I did say you could, so yes. Yeah. In the back end, all three of these options go to the same page on our website.

What's different is that there's a query parameter that you know says NPS poll answer likely, NPS poll answer neither, or NPS poll unlikely. And the question that we ask is this how likely are you to recommend trust insights as a consulting firm to someone in the next 90 days? Because this is essentially it's what it's a one of the best questions to ask in surveying for just general satisfaction, because if someone's not likely to recommend you, they either don't know anything about you or they really don't like you, right? Um, you could also ask questions like how satisfied were you with the service that you received today on you know today's uh plumbing visit or whatever. But I like this predictive question because there's a difference between how satisfied I am and whether or not I'm gonna promote you.

I'm gonna I'm gonna recommend you. And so I like this question as a promotion question. It's it's interesting because as you were saying that, you know, and this is the question that I that we'll get to of like what the heck do you do with it? One of the things I always I've always struggled with is I don't understand how this information is helpful, but now as we're talking it through, which is you know admittedly probably something we should have done a while ago or maybe before this show, because not everyone who subscribes to our newsletter is a client. However, what you're asking is, are we doing a good enough job of explaining our expertise and what we do so that if somebody said, Hey, do you know anyone who can fix my Google Analytics or you know, come and consult on a large learning model project, then you've read our newsletter and said, Yeah, I think Trust Insights does that.

That's what they're always writing about. So now it's like the the pieces are starting to click for me, but you know, I still need more information. But this is okay. I see where you're going with this. Yep, exactly.

And the advantage of using this style of collection, because these are just query parameters inside of a URL. A, there's no you're you're just using Google Analytics as the collection mechanism, and the answers are stored within GA. They're stored on a time-based format, uh, and they require no extra work. So if I go into our Google Analytics account, I go into explore. Um, I just start with the page path and query string, which caps is all the parameters and the number of events, and then I say I want to filter it based on that NPS poll answer.

Because you remember that's what we use as the query parameter in the URL. And now I can see neither likely, unlikely, and then there's a couple of anomalies there. So we can see like uh neither is and this is for the last 13 months, neither is 567, likely is 560, unlikely is 166. So to me, that's the just that alone, knowing that alone is like, okay, we're not like I would even be worried if it was evenly distributed. I'd be like, eh, something's wrong if it's evenly distributed.

But the fact that um neither or and and likely are way ahead of unlikely makes me feel better. Mm-hmm. Yeah, my first thought was, oh, people are neutral about us, but also, yay, people are neutral. Like, I think it's okay in business if you have an audience who they're they're kind of meh about you because not everything you do has to be a viral thing or solve everyone's problem. But you're still retaining that audience because at some point something you do is going to resonate.

So yeah, my initial reaction was, oh man. But now more the more we dig into it, it's like, okay, that's not that bad. Because they could be swayed either way. So now it's on us to make sure we move them in the right direction. Exactly.

And to your point earlier, the composition of the audience matters, right? So if we have, for example, a lot of college students, I'm just giving this up. If we had a lot of college students on our mailing list reading this, would they recommend us to a colleague? Probably not, because they don't have anyone to recommend us to in that sense. Like how would a junior at Wheaton College say, like, I'm gonna recommend you to my colleagues as a consulting firm?

Like that, you know, so they're probably in that case, answering either likely or unlikely because it's not that they don't like us, it's just they don't have anyone to recommend us to. Like, did you like the episode? Did you yeah, up or down? No, no, we don't do any tracking. I with the time delay, it's not like I would do anything with that info, anyways.

You know, I mean it's uh it's good to get into care. I a big part of it for us is you know, you know when you've done a good one because you see more chat around social media people talk about it, you know, and just nobody talks about the bad ones or passes them on. Um, but yeah, I don't know. For podcasting, there's not much as far as tracking and um, you know, kind of uh at the individual level. It's more about, you know, do you trust the brand and do they keep you entertained, you know, long enough?

Are they over time are they good enough to hold your interest? Um, which is really where it's at. Um, yeah, I don't know. I probably should. The the more interesting one is NPS for sponsors, you know, are you happy with the the leads that you're getting and the value you're getting out of supporting the audience?

And you know, do you have leads that come in that say that they found out about it through us? And yeah, thankfully we have a small enough audience that I'm able to get that kind of information personally, you know, that becomes part of two months after every package, go in and ask how things went and how many leads they saw and how things you know turned out. And uh yeah, it it verifies the results too. You know, you can tell at the end of the campaign if it was somebody that has nothing to do, you know, the uh uh folks selling shaving uh materials to a 50% female audience, uh, yeah, maybe that you know was not the best use of your money. And it's not surprising the results you get at the you know, when that wraps up.

Yeah. Now, there are other folks who are using this these systems and using them very well. So here's one this is uh uh newsletter called the rundown. And you notice this this is a daily newsletter. Um and they ask, how is today's newsletter?

Feedback's also improved, nailed it, average or epic fail. Again, thumbs up, thumbs down, you know, and and okay. This is this is if you have a publication that you want to assess, this is a great way to do it because not only do you get that that frequency of up and down and um things, but you can now you know the topics that were in that newsletter or the news or the the information you're sharing, you can get a sense of these articles or these topics, they yeah, these are the ones that people care about. You know, there's a uh they you nailed it that day. Other days, you know, maybe it was a thing on politics, and it was like eh, nope, I don't want to see any more politics.

And so you'll get an epic fail uh from your audience. So these tools are incredibly useful, and they follow the exact same format that we do. So just click on the URL, that's your vote, no extra work, and it allows rapid, rapid and good data collection. Like I said, this is right inside Google Analytics. So if you just want to do just the basics, um, let's look at the last 30 days, just the basics alone.

We have 38 likelies, 27 neither, and no unlikelies, which is pretty darn cool. Hmm. Take the win. Exactly. Take the win.

Yeah. Um so now, if you want to kick it up a notch, which I recommend you do, um, you want to take this data out of Google Analytics and put it into a format where you can get a better understanding of what's happening, particularly over time. So this is the exact same data, but it now uses the NPS score format. Uh the promoters divided by the total minus the detractors by the divide by the total equals your NPS score. And so for us, the green line represents 0.5 or above.

0.5 or above is where you want to be. The red line, which is zero, yeah, you do you do not want to be there. And so this is our last almost full year of this data. There's a minimum of 25 responses per month. If a month doesn't get 25 responses, it just won't show up because we didn't want to have like two people responding.

But thankfully that's that doesn't happen. And you can see since about April of this year, we've been above the green line more than we've been below it. And uh April was a really good month. Last month was a good month, the month before was a good month. So our our our NPS scores for our from our newsletter to our audience are generally very positive.

And this is a this is a big change from last year. Well, I'm trying to figure out, John, who do who did you upset in February that we got such low scores? I know. Hopefully not tied to Valentine's Day in any way. That's my concern.

But no, I mean, and it is, it's you know, I look at this and I'm like, that's great, we're up. But my you can imagine, Chris, what my first question is gonna be. So what? Why? Why or what what's the difference?

How do we like how do we know what we're doing well? What changed? You know, and so there's a lot to unpack when you see a very simplistic chart like this. Like you might be thinking, Oh, this I can present a very simple chart and people will understand it. Yeah, I see that we're up, but yeah, exactly.

So what? What do we do about it? How do we know what's working? Like, and then the million questions start to come. So, where do we start to unpack that information?

So, another useful thing about doing this surveying with your email newsletters, having that in there, is that if your email marketing software is any good at all, you get individual click tracking. So you could go back into your backend database for your software and say, for the last month, show me which of the 68 people clicked likely, and you can go back to those 68 people and email them and say, Hey, I noticed you voted likely. Why? What what made you likely? What you know, what did we do that you said, yeah, I want to recommend trust insights to uh to a colleague.

You can go to the the zero people, the ones who are unlikely and say, like, what do we do? What are we not delivering to you that that would help persuade you? And you go to those the the neither likely nor unlikely and say, Okay, well, what else could we do that would change your mind? If anything, to go from not uh, yeah, I don't know if I'm going to recommend you or not, to yeah, I'm gonna recommend you. So there's because you have that data at the individual level.

Now, obviously, we can't show it on screen because it's PII. Um, you can go follow up with people and say, what can we do better? Or what did you really like? I would imagine, well, not even I can imagine. I know for sure for a fact, um, that there's a way to automate that feedback process.

And so I've given feedback to other brands that I've gotten like customer service with, or you know, it's a lot of times where it's used as, you know, how satisfied were you with your customer service? And if you engage with the survey to see, like, you know, I would likely recommend or not likely recommend a lot of times you'll get an automated notice that says, Are you willing to answer a few more questions? And that's a way to get to that detail without having to take that manual step of giving John a list of people to go harass, and then our NPS scores go down because they're like, oh, chief statisticians after me. Now what does he want? He wants he wants my money, he wants my time.

More cold calls, maybe. Um, but yeah, automating that feedback um seems like a really smart way to approach it. And you're right, any decent marketing automation tool should be able to help you do that. Uh or a CRM system could absolutely do that. You can even do it right inside Gravity Forms, right?

Because again, we know who the person is. We have their their email address. So what they could do is they could click through and then end up on a page like this. It says, Hey, we got your answer. Do you want to tell us anything else?

Right. So I think that that's an excellent uh way to approach it. Exactly. So that's what you can do to get more granularity in the data to uh and to get that qualitative feedback um that can give you some direction with with the recommendation process itself, or it and it may reveal to you, for example, in the the feedback, yeah, I don't know who I could recommend you to. Uh in which case it's not a question of do we do something wrong?

It's that we didn't make clear here's who you should be recommending us to. Here's the type of businesses that we serve. Exactly. Makes sense. The other thing that, and and this is what I typically think of when I use this data and I look at this data is I see this data say the intent to recommend is higher in some months than others.

The intent to recommend is is above the green line. To me, that tells me that someone like John could be more aggressive in sales pitches to say, like, yeah, you know what? People are generally positive about us, people are generally thinking about recommending us. That's a good sign, as long as it's statistically valid. Um I'd be okay maybe with two sales promos this month instead of one, or I'd be okay with John doing some more um you know uh slightly harder selling or hitting more of the list of folks like, yeah, you know what, this person does it didn't demonstrate clear intent.

But when that number is high, say, you know what? They might not be they might be okay with hearing from John, even if they didn't raise their hand and say, I want to talk to John. This uh John asked that. When you look at February, like John, don't call anyone this month. Well, that's a big part of that though is using this to drill down and see who's who.

Like that's a huge part of it because it. Because you know, months like this month where we've given away a lot of top notch free resources. I mean there's a bunch of folks that we're hearing from that are at universities and you know single person shops and stuff like that. So really, you know, digging down in to see who's who is huge. Because even even on a bad month if I if there's a Fortune 500 CEO that rated us a nine, you know, I I want to see what's going on there.

Exactly. I wonder too and I'm I'm assuming if we have enough data we could do this kind of you know matching. Uh I don't necessarily want to call it a correlation because I don't know if there's enough but you know do the peaks and valleys of the NPS score correlate with like um was it budget seasons or you know anything else? Like is there some kind of seasonality to the NPS scores where we could be like oh well we know you know every April our NPS score goes up because for some industries that's the end of their you know financial year. So they're looking for new partners versus February where the new year just started and everybody's already burnt out from trying to figure out what the heck to do with their fancy new budgets and some companies have already blown through 70% of it and it's only February.

So no they're not going to recommend us to anyone so I when I look at this that's what I would be curious to know is does it match up with any other kind of data that would help us understand not only what are we doing well and what are we doing wrong, but there's a seasonality to it. So, you know, in the example of like giving John, you know, either like hit the gas or pump the brakes, knowing ahead of time, like we know April's going to be a big month. Like, we can look at our our own sales data and know like what months. So that would be interesting too to see like, does this correlate with our better months than you know, just looking at this by itself? And that's exactly right.

Uh, however, we only started doing this in a reliable, repeatable format in October of last year. We did it sporadically in the past, but it was never something we were disciplined about until last year. Like, eh, we just need to start rolling this uh calm hell or high water every single month. First newsletter of every month, this goes in the newsletter. And we have not missed any since October of last year.

So we would need probably at least another year's worth of data just to be on the safe side. However, we also do have data that's qu uh that's quantitative survey data with every form film, right? We ask people what are the things that you uh you're interested in for yeah, yeah, you know, better measurement, better tools, understanding ROI and things. And so we could certainly take this data and do that cross-correlation analysis with that, do it with the website data, do it with social media engagement data, do it with the number of opportunities or contacts in Hubspot. So there's so many things that you could do that that multiple correlation analysis to see what of those things has a correlation to this data.

And then that gives you the starting ingredients to do, okay. Well, now how do we prove any causality? And I think that that, at least for me, that's the kind of when you say like the so what, that's where my brain goes immediately, like, well, does this align with you know budget planning? Does this align with our sales data? What else could it potentially lend with?

So, like you mentioned social media data. I don't know that for me that would really tell me anything, or I could really do much with that because social isn't a high performing channel for us. I would be interested to know like number of net new email subscribers month over month, because since we're sending this out over email and email is one of our stronger channels, does the number of net new email subscribers correlate to how high the NPS scores go? Because they're people who've never heard of us before. Or they're brand new and they're super excited, and then they kind of like, you know, we fall into the background noise after a few months.

Mm-hmm. Yep. No, I I those are all valid questions that the data can help answer. It's just a question of do you have the time to to put that together? And now the good news is these days the answer more and more is yes.

Katie, you and I were talking about this uh in our company Slack not too long ago, about using tools like chat GPT's advanced data analysis to be able to do those analyses. Because even if you are someone who can't do the mathematics or the coding with a tool like that, you can give it the data and say, I know what I want, I can put it into words. I just can't write the code. It will write the code, and then you can get your answers. So, okay, so we've been talking a little bit about like what we do, but if you were to hand this data to an executive, what kind of an action plan would you put together for them?

What what actually do they do? Because we've been kind of circling around some ideas, but what should someone be doing with this data consistently? To John's point, most executives just uh either give themselves a bonus uh or just bury it quietly on the shelf. Right, or fire the customer service VP, right? The institution staff change over there.

Um, the next thing to do is that qualitative research. You you ask people, okay, why? Why would you recommend us? Why would you not recommend us? And again, it could that can like you said, be programmatically integrated into the system, which is something we're gonna look into uh because it seems like a pretty straightforward thing to do.

And then again, from a sentiment perspective, being able to look at the data and say, okay, John, here's here I think it's safe to turn up the heat, or maybe it's not. Maybe let's let's you know deal with the inbounds as it come in, but but don't be chasing people down. Um so those are the things that I would say it belong in an action plan is you have this intent, you can rely on that intent to make decisions to to do more or less of something. If this was customer service satisfaction data from like a call center, um, then you would say, okay, well, clearly we need to be more carefully measuring our call center representatives as to the as to the individual satisfaction that we collect after each call. Um, JetBlue, for example, uses this exact system to rate every leg of a flight.

And they look at uh flights and say, okay, wow, something really went wrong from this New York City to LAX flight that everyone rated it at a one. Um, and then they can go dig into that and say, Okay, well, here's here's what happened to that flight. Oh, it was a two and a half hours late leaving the gate and the restrooms didn't work. Um, and so there's some explanation there, but the key to this data is to use the data in in any fashion. Don't don't just take the chart, like do something with it.

I was gonna I was gonna mention that is that yeah, it's great to collect the data, but that that's sort of where people get lost. And that's whole that's the whole basis of Trust Insights is we light up dark data. Don't let this become another piece of dark data that just sits on your shelf that you collect, you don't know anything about because you start to get into that, I guess essentially data debt of you have all these pieces, and then you have to go back and sift through it and clean it up and figure out, and then you know, you could find that the majority of people who said they would recommend you are no longer part of your ecosystem, they're not subscribers, they're not in your audience, so you can't go back to them and be like, Oh, well, remember like five years ago when you said you were gonna recommend us to someone? Would you still do that? Because they're gonna find that pretty annoying and creepy, and then John's gonna get really low NPS scores all over again.

It's a vicious cycle. You know, this is a great way for slicing data though when you've got a problem, because the one thing you can do is uh you know, you do the first cut, and then you can take everybody seven and below and send them an email saying, Okay, we realize you're really angry with us and have a problem, and you give them the five key areas where you normally have trouble with, and so now you've got them sliced again, and you can you know get to the the core of what's going on, you know, like the classic Amazon reviews, right? Was it because it was damaged in shipping? I always love to see that people, you know, a product getting a one star because it came to my house crushed, like not that the company has anything to do with that but uh you you can kind of weed out the the basically the folks that are just off their rocker from the ones that have legitimate complaints and at the whole time you're not bothering anybody that's happy or content. You know, you're only working with the the group that needs some attention.

And that's a really important point for customer satisfaction because as we saw at the dawn of public social media, different channels get different satisfaction levels, right? Your your Twitter call center versus your email call center versus your telephone call center all may have very different satisfaction scores. And they should, right? They should all be equal or close to equal because it means you're delivering the same level of service. And if you're not, then you've got some training and education to do to help the call centers reach the same level of hopefully improving satisfaction.

When we were working at the agency, Chris, my recollection, and you know, correct me if I'm wrong, is that so I know that that's where I was first introduced to NPS scores. I'd never heard of them before, uh, prior to joining a public-facing agency. Um that was a score that they would then also promote publicly of like, look how great our NPS scores. This is why you want to work with us. Is that a common practice for a lot of companies to say, like, look, we have a really high NPS score, so we're the ones you want to work with.

I mean, if you saw a job ad that was advertising that, how would that make you feel? Oh, I would think it was complete BS. I mean like the lady doth protest too much. I mean, they there's your answer. I mean I'm also super skeptical of everything.

So I'm an N of one. You're not though. I mean, it's it's one of those things that if you have to say it, it's probably not true. Whereas if somebody else says it about you, okay, like i I would believe a lot more going out to a site like Glassdoor and seeing what current employees have to say about that company rather than what the company has to say about itself. Like I yeah, it's like someone calling themselves a guru or or a ninja, like, okay, you you're not either of those things, and I have the throwing stars to prove it.

Um but it is I would be very cautious about about that because A, it relies on people understanding what an NPS score is as it relates to employment. B it does make if you think about it from a a non-measurement person's perspective, it means so am I gonna be like constantly monitored if I work at this job that they're touting these weird scores on their job ads, like you know, do I you know what kind of tests do I have to take on a regular basis to feed that data? But I think depending on your role, you know, if you are like head of the customer support team, then it's a relevant score. I used to work uh at a phone bank, I worked customer service, I'm sure all of us have at some point in our uh careers. And that was it was one of the things that I was measured on because as the person taking the call for the customer, you know, we were rated on, you know, how quickly we got through the call, the volume of calls, and if the person got the information and if it was accurate.

Um, and so that was sort of our version of the NPS scores. And so I can see where it is a relevant metric for certain job roles, but it does also feel like a really antiquated way of measuring job performance. It it can be it can be useful too. So there are one of the things that companies have been struggling with scaling, right? Customer service is one of the hardest things to scale because it requires it requires people and lots and lots of people.

And if if you don't have those lots and lots of people, and those people are not trained well, yeah, it's gonna be you're gonna have some some trouble. This is where, by the way, and this is gonna come uh full circle to a whole bunch of other things. There was a recent paper uh published by NIH about generative AI and its use in customer experience. The the summary of the paper is that generative AI on average delivers a better customer experience than the humans do, um, because for for a couple reasons. One, there's no time limit, right?

With uh when you have a customer call center, uh, one of my friends worked at a uh customer call center for a bank and they had a a five-minute window. They were penalized in their internal scores as an employee if a call lasted more than five minutes, which to me is kind of nuts. It's like, oh hey, someone broke into my account, you know, and they're committing fraud, and like, nope, you have to solve it in five minutes or less. Um, and because of that, the reps also were highly incentivized to end calls as quickly as possible, including just outright hanging up on people, um, which made the customer satisfaction scores go into the toilet. When you compare that to a generative AI system where you don't have to worry about staffing, you don't have to worry about uh you know five-minute limits, and you can spin up as many instances of the chatbot as you want, of course, the you're just trying to get better results because it's on the customer's pace and time then.

And so you'll see those NPS scores go way up where the customer is effectively not on the clock, right? The customer is not being met, you know, penalized for having problems that require a lot of time to solve. It's it's interesting. Um customer experience and customer support is historically such a human thing, and I know our friends over at B Squared, like that's their whole platform, is that it is a very human experience. And so it's interesting that NIH came out with this study that it you're saying, Chris, that the generative AI is better than humans at the customer experience.

Does it get into like what that specifically looks like? Is it answering basic questions? Is it you know how like what is it that it's better at? They were specifically measuring quality of responses, and this was um both in marketing. There's a there's another version of this paper that actually is in medicine, which itself is very interesting, where the the chat GPT responses were rated as higher quality, more informative, and more empathetic when chat GPT gave the answer versus a human doctor, which was like, okay.

Um, but again, it's a language model, it's trained to deliver language in a certain format. But that's what we're seeing with these tools. And so if if you're thinking about NPS scores and deploying them, one of the actions you might take is investigating the possibility of can you can you divert? It's called actually literally called call deflection. Um can you deflect or divert enough a certain percentage of calls to a machine that will solve those calls in a way that is satisfactory to the customer that makes them happier than the humans, and then leave that reserves the humans to handle the really difficult stuff.

We're like, yeah, you know what? This is gonna be a 30-minute phone call between three departments company because you've got a crazy fraud case to deal with. That's where these NPS scores will help us measure different modalities of providing a good customer experience, and then also allow us to re-resource because now if I can divert 60% of your call volume away from your call center, the regressive company will be like, great, we can cut 60% of our workforce. The progressive company will say, okay, let's now give our call center reps to stay a five minutes per call, let's give them 15 minutes per call and see if the call center NPS scores now go up because customers are going to get better treatment because the easy questions are all being handled by machines. What do you say, John?

Are you would you rather interact with a machine or would you rather interact with a person when you're calling customer support? Yeah, you know, it doesn't matter really. I just want like the answer as quickly and correctly as I can get it, which is the thing. But it's very is really interesting to me on the healthcare side of that, because there's been a lot of research already and things done about how you know working in healthcare fatigues the employees. You know, it's like if you have to spend your whole day dealing with burn victims, you know, eight hours of that, you're you just are not gonna have the patience and the ability to do that.

So and and we even see this at home with seniors too, you know, things like Alexa being able to Alexa will tell you what time it is 500 times a day, you know, and she doesn't care, and you're not gonna lose her temper with whoever's in the house. So yeah, there's a lot of customer service stuff that should be outsourced like that because yeah, infinite patience in the machine is actually something that's gonna improve experience for a lot of people. Um and then and then it's as Chris mentioned, like you save the humans for the stuff that's a complete dumpster fire that's never been seen before. You know, that's when a human can cut through it faster. But for the yeah, the the six hundred and fifty-fourth time somebody's called you and you tell them to reboot your phone, you know, you really don't need a human to be doing that.

Exactly. Hmm. We have to give Alex a shout out though for his uh NBS. He said, is that uh a subset of what we should be scoring? Yeah, that's what I think of those scores.

I think they're NBS. Um so it's you know, we definitely we at Trust Insights have some uh modifications to make to our own uh data collection system. But I feel like I have a better grasp of why we do it in the first place. And I feel like that's always you know, where companies should start. Like it's great to collect this information, but you know, go through the five P pro process.

What is the question you're trying to answer by collecting this data in the first place? Because it might be different. So, you know, it might be, you know, how efficient is our customer support versus how likely are you to recommend us to someone else? Those are two different questions. They might have the same structure to the survey, but you're asking very different things.

So you want to be sure that you're clear about that and that you have a plan to actually use the data. And that's that is the number one takeaway. Have a plan to use the data. Data that you just collect is just a waste of time. So have a plan to use the data.

Um, and to your point, Katie, make sure that you know what that use is. Make sure you're clear on the purpose of it so that you can use it intelligently. Yeah. All right. That is gonna do it for customer satisfaction scoring data and stuff.
