Why Functional Needs Alone Aren't Enough

What do Spotify, Google Meet, and your expense report tool have in common? They could all delight your users—if you design for more than just function. In this episode, Dr. Nesrine Changuel breaks down the emotional motivators that transform average products into unforgettable ones.

Overview

What separates a good product from a great one? According to Dr. Nesrine Changuel, it's not just meeting functional needs—it's creating emotional delight. In this episode of the Agile Mentors Podcast, Brian Milner sits down with Nesrine, a former product leader at Google, Spotify, and Microsoft, to explore how emotional connection is the secret sauce behind the world’s most beloved products.

They dive into Nesrine’s “Delight Framework,” reveal how seemingly mundane tools (like time-tracking software or toothbrush apps!) can create joy, and explain why delight isn’t a nice-to-have—it’s a competitive edge. Whether you're a product owner, product manager, or just want to build better user experiences, this episode will change how you think about your backlog forever.

Welcome back Agile Mentors. We're back for another episode of the Agile Mentors podcast. I'm with you as always Brian Milner and today I have a very special guest with me. I have Dr. Nesrine Changuel with me. Welcome in Nesrine.

Nesrine (00:14)
Hi, Brian. Thanks for having me.

Brian Milner (00:16)
I'm very excited to have Nesreen with us. I think this is going to be a really, really great episode for all of you product owners out there or product specialists, anybody who works in the product area. I think you're going to find this really interesting and you're going to want to bookmark this one. Maybe even come back to this a little bit. Nesreen is a coach, a speaker, particularly in the product area. She has previously worked at Google. She's worked at Spotify, at Microsoft, so no stranger to large enterprise, very high profile products that she's worked on in the past. She has a book coming out in May, so look for this book. It's called Product Delight. And that's really what we're going to be focusing on here is the concept of eliciting or generating kind of an emotional response to our product. I guess I'll start by, did you stumble upon this? What drew your interest to people's emotional response to products?

Nesrine (01:19)
Yes, so maybe I can share the story how I came to this topic and how I became so vocal about it. So in addition to being a product manager and leader over the last decade, I was always and I always enjoyed being a speaker. So I always wanted to go on stage and share insight. This is probably coming from my research background, because when I used to be a researcher, I traveled the world to go and present my research work and When I became a product manager, I kept this habit with me. So I always been on stage and I spoke about different topics like product discovery, product operation, different topics. Until one day I got reached out by a conference organizer and he said, Hey, Nisri, we want you on stage, but we have an idea for a topic for you. I'm not that used. Usually I come up with idea myself, but I said, okay, what do want me to talk about? And he said, Hey, Nusreen, you have been working for Spotify, for Microsoft, for Google Chrome and Google Meet, and we all admire those products and we consider them very successful products. What if you come and tell us what's the common thing that probably is there any common thing that made those products successful? Being an insider, being within those company, could you share with us something that you consider in common between those products? To be honest with you, I found it challenging at the same time interesting as an exercise. I was not, by the way, able at that time to answer the question, what's in common? So I sat down and I did the exercise myself and I started to think what was really in common? What made Skype Skype? What made Spotify Spotify and those Google products so successful? And I came to the following conclusion. I found that what made those products so successful is that they don't only solve for functional needs, but they also solve for emotional needs. So when we use a particular product, we use it for a certain functional need, but we also use it for an emotional need. And without even knowing that I have been doing it for more than 12 years, I came to the conclusion that, my God, during all those years, I have been focusing so much into users need from both angle, functional and emotional. So I came on stage and I spoke about that topic and from that day, I started to give it a name. I'm calling it emotional connection. I'm calling it product delight. And I'm here to share more about it as well.

Brian Milner (03:50)
That's awesome, yeah. I mean, I think we do hear a lot and we focus a lot on that functional kind of need, the way you differentiate there. think that's a good differentiation, functional and emotional kind of needs or motivators there. yeah, I mean, I've always heard, know, kind of that kind of general product advice is, you know, find the things that... people really, really have as huge needs, the things they would pay someone to do for them. And that's the key to success is finding those huge needs. But we're actually going beyond that to say, yeah, those are important. It's not to say that we should skip that, but it's when there's the emotional connection to a feature or to something that we do that really the light bulb kind of comes on for our customers. Is that kind of what your research is leading to?

Nesrine (04:40)
you're getting it right. Don't get me wrong. Of course you have to honor the functional needs and serve the functional feature, but the delight or the emotional connection happens when you go beyond exactly how you said it. Let me explain. If you serve only functional needs, you know what you get? You get satisfied users because they are asking for something and they are satisfied about what they are receiving. Now,

Brian Milner (04:41)
Okay, okay. Haha.

Nesrine (05:05)
If you surprise them by going beyond, by anticipating their need, by exceeding their expectation, you're not only satisfying them, you're surprising them in a positive way and delight is the combination of surprise and joy. Actually, the theoretical definition of delight is a combination of two emotions, surprise and joy. So going beyond, anticipate need and exceed expectation. is what we should aim for in addition to the functional needs.

Brian Milner (05:35)
That's awesome. Yeah, I use this example sometimes in, we use this example in the agile world to talk about, you know, the part of the agile manifesto that says customer collaboration over contract negotiation. And, you know, there's an example I use from my past where I used to work at a company that was very contract driven. And, you know, the thing that I always used to kind of take away from that was the very best we could ever do or hope to do. was to meet our customers' expectations. We could never, ever exceed it because we were only doing exactly what they told us to do. So I think this is a really important distinction here to make that just meeting the customer's needs, just meeting the minimal customer satisfaction bar, that's not going to keep you with loyal customers. That's not going to have repeat customers, or they're not going to tell their friends about, you know. That product did exactly what I hoped it would do. But it didn't really surprise me. It didn't really go beyond that. I know you talked about, because I've read your blog and a little bit of the discussion about this. So I know you talk about in the blog kind of the connection to Kano analysis. And I've always thought that's a really great way to try to determine things to target and go after. So talk to us a little bit about that, about Kano analysis and kind of what that uncovers and how that connects to what your research has shown.

Nesrine (06:51)
Yes. I love Kano by the way. I, I mean, that's one of the framework I have been considering throughout most of my product career. But this framework comes with a limitation and let me explain. So first of all, for those who are not very familiar with Kano, Kano is a visualization or categorization, let's call it. It's a categorization framework that allows to categorize features among different categories. One of them is must have. So these are the things that absolutely have to be in the product. Other that are performances, which are the more you have, the more satisfied users are, the less they less satisfied they are. And of course there are the delighters and delighters are those feature that when they are in the product, users are surprisingly happy. And when they are not, are not even the satisfaction is not even impacted. So the limitation of Kano is that it doesn't tell you how to achieve delight. Let me explain. I think we live in a world that everyone agree that we should delight our users. I mean, this, this concept is now globalized and everyone is talking about delighting users. The issue is that we don't know how to delight them. So we know category, there's a category that called delight, but we don't know how to. So the, the framework that I'm introducing and I'm calling it the delight framework is the framework that allows to first identify. So it's usually, represented into three steps. The first step is to start by identifying the emotional and functional motivators. So let me give you an example. I've been working at Spotify for about four years and as a Spotify user, imagine yourself, you are a Spotify user. You do have, of course, functional motivators. What could be the functional motivators? Listening to music, listening to podcasts, maybe listening to an audiobook. So all those are functional motivators. Now, what could be the emotional motivators as a Spotify user? It could be feeling less lonely. It could be feeling more productive because when you're working you need to listen to something. It could be about changing your mood. It could be about feeling connected. So all those are emotional motivators that drive users to use a product like Spotify. So what I encourage every product manager or every product team to do at first is to dig into identifying, of course, the functional need. And everyone is good, by the way, in identifying the functional needs. But also, while doing that exercise, pay attention to what could be the emotional motivators. So that's step number one is about listing the functional and the emotional motivators. Once you have those, Now we get to the second part of the framework, which is look at your backlog. And I guess you have a very busy backlog and take those features one by one and see for this particular feature, which motivator am I solving for among the functional ones and among the emotional ones as well. So the delight grid, for example, is a visualization tool that I came and created in order to allow product teams to visualize their backlog and see how many of my features are only solving for functional motivators. In that case, we call that category low delight. How many of my features are only solving for emotional motivators? These are very rare, but the best example I would call is, for example, I'm having an Apple watch and one month ago it was New Year Eve and at midnight I get fireworks popping out of my

Brian Milner (10:35)
Ha

Nesrine (10:36)
Apple watch and it was a happy new year there's nothing functional in there but it's all about creating some smile I call this surface delight and then how many of your features are solving for both functional and emotional motivators and I call this deep delight so maybe I deviated a bit from your question compared to canoe but it's actually about adding this dimension of connecting features to the real motivators of the users.

Brian Milner (11:07)
No, maybe a little bit, but you connected it to where we end up going anyway. So I think that's a great connection there. And by the way, for anyone listening, we'll link to all of this so that you can find this and follow up. But I like that differentiation between surface delight and deep delight. I know some of the examples that I've heard used kind of frequently in looking at Kano analysis and kind of trying to find those delighters. And that is kind of the area that it specifies there in Canoe, right? You're trying to find those things that are not expected, but when people find that they're there, they like that it's there, but they don't expect it's there. So if it's not there, there's no negative response that it's not there, but there's a positive response if it's there because they like seeing it. And my boss, Mike Cohn, tells this story about this

Nesrine (11:59)
Yes.

Brian Milner (12:03)
There's a hotel in California that became famous because at the pool, they have a phone that's by the pool that's the Popsicle Hotline. And you can pick up the phone and you can order a Popsicle to be brought to the pool. And it's the kind of thing where you're not going to go search for a hotel. Does this hotel have a Popsicle Hotline? I'm only going to stay at hotels with Popsicle Hotlines. It's not that kind of a normal feature. It's a delight feature because when you see it and you find out it's there, it's like, that's really cool. And it can be the kind of thing that says, yeah, I want to search that hotel out again next time I'm in this area because I really thought that was a nice little attention to detail and it was fun. But I think what I'm hearing from you is that might be more of what we would classify as a surface delight. It's not really meeting a deep need.

Nesrine (12:35)
Yes.

Brian Milner (12:56)
But it's fun, it's exciting, it's not expected, but it doesn't really cross that threshold into, but it also meets kind of functional delights. Is that kind of what you're saying there? Okay. Okay.

Nesrine (13:08)
Yes, actually I heard about that hotel story just to tell you how much viral it went. It came to me. So actually you get it correct that I consider that as surface delight and I have nothing against by the way, surface delight. You can add surface delight. The issue is you can end up doing only surface delight and that's not enough. So the idea is to do a combination and I do have two stories to share with you just to compliment on this hotel story. One is personal and one is professional. Brian Milner (13:21) Yeah. Okay.

Nesrine (13:37)
The personal one just happened to me a month ago. I went to Sweden and I went to Stockholm. That's where I worked for eight years. And I went there for business and I decided to meet some friends and some ex-colleagues. So we all gathered and went to a restaurant, a very nice restaurant in Sweden. And came the time where we had to say goodbye and to pay. And I guess you can feel it immediately when it's about paying and we are a large group and you start to get that anxiety about who's paying what and what did I order? What did I drink? What? I mean, I honestly hate that moment, especially in a large group where you don't necessarily have a lot of affinity with us. Like, should we split in 10? Should we pay each one paying its piece anyway? So that was a moment of frustration, of anxiety.

Brian Milner (14:09)
right. Yeah.

Nesrine (14:28)
And I loved how the restaurant solved it for it. You know how they solve for it? I mean, maybe it exists in the U.S., but for me, that's something I never seen before. The waiter came with a QR code on a piece of paper and you scan the QR code. And when you scan your QR code, you get the list of items that got purchased by the table. And all you have is to pick, and that happens automatically real time. Everyone is picking at the same time. You pick the things from the list and you pay. for the things that you order. You can even tip on the bottom. You can give feedback. Everything happened on that QR code. And you can guess how much that anxiety could be removed. So that's the personal story I wanted to share. The second story, which is more professional, I want to share how we try to improve experience at Google Chrome. So I've been the product manager at Google Chrome.

Brian Milner (15:13)
Yeah.

Nesrine (15:25)
And we started from the observation that people do have plenty of open tabs. I guess you are one of them, especially on mobile. Like on mobile, you go and check how many open tabs you do have on Chrome and you realize that they are have, we realized at least out of numbers, out of data that people do have plenty of open tabs. So it started as

Brian Milner (15:32)
You

Nesrine (15:47)
technical issue. Of course, the more tab you have, the heavier the app is, the slower the app could be, et cetera. So we wanted to reduce the number of unnecessary open tabs in Chrome. So we interviewed users and we started to check with them, why do they even leave their tabs open? So some of them leave tabs because they consider them as a reminder. I mean, if tab is open, it means that you need to finish a task there. Some people really leave tabs just for ignorance. mean, they moved from a tab to another and they completely forget about them. Actually, we realized that the fact of leaving tab open, the reason for leaving tab could be completely different from a person to another. And the other interesting observation, and when I say identify emotional motivators, you will realize that people feel a bit ashamed when they show to us that they do have plenty of open tabs. Some of them would say, sorry, I usually don't even have so many open tabs. It's only now. And I'm like, it's okay. But the point is, if you have this mindset of trying to track the emotional insight from your users, you will take note. And the note was anxiety, feeling ashamed, blah, blah, blah, blah, blah. And that was in introduction for in...

Brian Milner (16:42)
You Yeah, right.

Nesrine (17:04)
improving the tab management experience later on in Chrome.

Brian Milner (17:07)
That's actually a really good parallel, though. I think that's a good example because it reminds me, too, even going back, I remember one of the things, and I'm going way back here, but I remember one of the things about Gmail that was kind of a selling point initially was the concept there of you don't have to worry about maintaining an inbox. keep all your mails and search. And you can search through your mails and find whatever it is. And I remember prior to that, most people would use something like Outlook or something like that to have their mail, there was always this constant struggle of, I've got to keep it down. I've got to delete things. I've got to categorize things. And Google had this different approach of, don't worry about it. Just leave it. And that's a good, I think, example as well of kind of that emotional response of,

Nesrine (17:48)
Yes.

Brian Milner (17:56)
Gosh, I'm kind of anxious. I feel bad that my inbox is so big. And I know that's bad, but Google comes along and says, don't worry about it. You're not bad. It's OK. Yeah.

Nesrine (18:05)
Yeah, yeah. And by the way, I think Gmail is filled with plenty of deep delight features. One of them I can quickly highlight is, you know, when you send an email, we're saying attached file and the file is not there. And when you try to hit send, you get that pop up like a be careful or like a mind, there is no attached file inside. These are for me like very attached to the fact that You don't want to feel ashamed. You don't want to look stupid later on saying, Hey, sorry, I forgot the file. Here's the file. That's, that's a great example. And the other example that come to mind again in Gmail, you know, that smart compose when you're trying to answer an email and you can just hit tab, tab, tab to complete the sentence. I mean, the functional need is to write an email. The emotional need is to get it in a relaxed way. And the combination would allow for something like.

Brian Milner (18:49)
Yeah.

Nesrine (19:00)
Smart Compose.

Brian Milner (19:01)
That's awesome. Yeah, so I guess that leads to the question though, when we're talking about something like Spotify, mean, music intrinsically is emotional anyway, right? It's something that you have an emotional connection to and you feel a certain way when you hear music. But if my product is a, I don't know, expense reporting software, right?

Nesrine (19:23)
Mm-hmm.

Brian Milner (19:25)
I can just hear people out there kind of asking, know, and kind of thinking to themselves, yeah, but my product, right, my product is not that kind of, it doesn't elicit that kind of emotional response in people the same way music would. So does this apply to me as well? So how would you answer those people who feel like my products might be a little bit more bland or boring and don't really intrinsically have an emotional connection to them?

Nesrine (19:47)
Mm-hmm. So my answer is that if your product is boring, then it's even more priority now to focus on emotional connection. But let me elaborate. So that's one of the reflections that came to my mind while writing the book. So while writing the book, I wanted the book to be a storytelling book. So I was writing a lot of my stories, stories from Skype at the time, Spotify and all the Google product. But at some point I said, hey, hey, Nisreen, you need to get more insight from other people and other experiences. So I get to interview product leaders from completely different industries and completely different domain. I interviewed leaders from B2B like Atlassian or Intuit and so many other companies that I don't have so much insight from. I even interviewed people from hardware, like I interviewed someone from Dyson and I was, hey, what makes Dyson so emotionally attractive for me? Cause I love my Dyson vacuum cleaner. But let me get to your point because when I interviewed someone from Intuit, that person told me something super interesting. She told me that at some point she was working at a tool called Tsheet. And Tsheet is a tool that allows you to enter your time report. There is nothing more boring than that. I think I'm picking the one that you're looking for here because it's, it's as a user. The only reason I would use this tool is to report my time so I can get paid.

Brian Milner (21:06)
Hmm. Right. Yeah.

Nesrine (21:19)
There is nothing exciting, nothing emotional. And what I got out of that product leader who used to be the head of product at the time, she told me that they were completely aware about the fact that the product is not that attractive. And instead of living with that observation, they did all what they could do to make it even more attractive. So they added some fun. They made the messaging less aggressive and less about enter your time. report but rather into more playful and even the images are more playful. When you press the enter time report you get the congratulation and some confetti if needed. So they explicitly turned and that's a strategy. They turned that boring moment into something even more attractive and they had to do that otherwise the experience will keep on becoming more more boring and the perception of users toward the product will be even less, more and more gray, I would say.

Brian Milner (22:22)
Yeah, yeah, just that little dopamine kind of kick, right? Just that little bit of chemical reaction in your brain can make a huge difference. That's awesome. That's a great story and a great answer to that question. So I'm curious, we're talking about trying to find these things and trying to see, your matrix here, it thinks about the emotional motivators, the functional motivators, and trying to find those things that kind of cross both planes.

Nesrine (22:24)
Yep.

Brian Milner (22:52)
How do you verify at the end? Because if you're lining your features up and think, I think this solves this emotional thing. I think this solves this functional thing. Is there a way to follow up to ensure that it actually is doing that? How do you follow up to make sure it's really doing what you thought it would do?

Nesrine (23:09)
Yes, so let's imagine you did the exercise well, you filled in the delight grade and you observed that you do have plenty of low delights, which is most of the cases by the way. The very first thing I recommend is to see opportunities for moving or transforming these features into deep delight. And in the book, for example, I talk about the nine delighters. Nine delighters are ways that could be sometimes cheap even to introduce. in order to make those low delight features into more deep delight. This could be, for example, through personalization. We love when the features are personalized, and that's one of the reasons, for example, why Spotify is so successful, is through features like Discover Weekly or RAPT or these kinds of super personalization related features. It could be through seasonality. That's, for me, the cheapest and the most delightful feature you can or aspect of feature you can add to your product. So for example, when I worked at Google Meet, I've been working at the background replace features. So we have been, of course, introducing static image. We have been introducing video backgrounds as well. But from time to time, we always use seasonality to introduce what we call seasonal background. So when it's Easter, we introduce Easter background. When it's Christmas, we introduce Christmas background. Guess what? Even like for Olympic game, we introduce Olympic game background. When it's the Earth Day, we introduced Earth Day background. So there is always an opportunity to introduce some seasonality to the product. And guess what? We relate to those, especially if the product is global. We relate like last, when was it? Like last Wednesday. It was the new year, the Chinese new year. And I was checking when is exactly the exact date for the new year, the Chinese new day. And I put that and you know what happened in Chrome? It got these dragons and those like the celebration within the product, like within Chrome. These of course are surface delight, but you know what? Why not? You see? So there are some tools. Some of them are not that...

Brian Milner (25:17)
Right.

Nesrine (25:22)
expensive to introduce to the product. Some would require a bit more thoughtful and thought into it, but there are ways that I detail in the book in order to introduce more delight. And then if you want to validate through metrics, and I guess that's your question where it's heading to, then the good news, and that's something that I discovered recently because there's been a study that was conducted by McKinsey. And you know what they studied? They studied the impact of emotional connection on product adoption. So they actually studied over, I don't know how many industries die, like tourism, IT, energy, whatever. And they interviewed more than 100,000 users or whatever. So the conclusion that they found out of that very interesting study is that emotionally connected users will get you more twice as more revenue, twice as more referral, and twice as more retention compared to satisfied users. I'm not talking about the non-satisfied. So if you take two groups of users, those that you satisfy their needs and those that you go beyond and they are emotionally connected, those that are emotionally connected get you twice revenue, referral and retention.

Brian Milner (26:19)
Hmm.

Nesrine (26:43)
So this is just to highlight that for people who say, no, but this is the cherry on the top. This is just like the extra. It's not the extra, it's the way to stand out. I don't know any company that is standing out nowadays without investing into emotional connection, none.

Brian Milner (26:54)
Yeah. That's a really good point. Yeah, I mean, the example that comes to my mind when you talked about seasonality and other things like that, know, I love my, you know, they're not a sponsor, Oral-B toothbrush, you know, the electronic toothbrush, and you know, there's an app with it and it keeps track of, you know, did you get all the areas of your teeth and did you hold it there long enough and... One of the things I always love about it is when it gets to December, the opening screen when you open up the app starts having snowfall. It's kind of a funny little emotional response, but you look at that and you think, that's cool. Yeah, it is kind of that season where now it's time to get ready for Christmas and it's that special. It's only this month that it's going to be like that. It's going to go away at the end of the month.

Nesrine (27:45)
Yes.

Brian Milner (27:49)
feel little sad when it's gone, it's back to normal. But it's such a silly little thing. Does that make any difference in really brushing my teeth at all? Does it change how well I brush my Not really. It's just a fun little thing that when it pops up there. And think how little that took from someone to do that. It's a little animation that they just pop up on a loading screen. But that little tiny bit, think, again, maybe a little bit surface.

Nesrine (28:10)
Yes.

Brian Milner (28:16)
but it takes something that would have been routine. It takes something that would have been kind of boring otherwise, and it just added a little bit of fun to it, you know? And I think you're right, that emotional connection is really, really important in situations like that, yeah.

Nesrine (28:21)
Yes. Yes. Yes, yeah. And the thing that I'm very vocal about nowadays is the fact that this emotional connection is actually not a new topic. It's something that has been extremely popular among marketers. For example, if you think about the best marketing campaign, they are all very emotional. The most successful marketing campaign are. If you think about designers, there are plenty of resources about emotional design. There is a great book by Don Norman. It was called emotional design. Aaron Walter as well wrote something called Designing for Emotion. But you know, the problem is that among engineers and among product manager, we don't talk that much about that. And you know what happened when we are not informed about this topic? There is a gap between the language of marketers, designers, and the engineers and product manager. And that gap doesn't allow things to succeed. I'm trying to educate the engineers and the product world towards this well-known domain outside of the product in order to have this consistency and start making real impactful products.

Brian Milner (29:40)
Yeah, yeah, this is such a really deep topic and it just encourages me, think, even more to recommend the book there. It's not out yet, time of this recording it's not out, but it's going to be in May of 2025. That's when this book is coming out. And I know it's gonna have a lot of really good information in it. Again, the book is gonna be called Product Delight. by Nesrine Changuel, Dr. Nesrine Changuel. I should make sure I say that. But I really appreciate you coming on because this is fascinating stuff. And I think the product managers, the product owners that are listening here are going to find this really fascinating. So I appreciate you sharing your time and your insights with us, Nesrine.

Nesrine (30:26)
Thank you, it's my pleasure. I love talking about this topic.

Brian Milner (30:29)
Ha
