Empathy Map – Why and How to Use It

Personas are one of these things that gets used  in very, very many ways during design. A persona is a rich description or description of a user. It's similar in some sense, to an example user, somebody that you're going to talk about. But it usually is not a particular person. And that's for sometimes reasons of confidentiality.

Sometimes it's you want to capture about something slightly more generic than the actual user you talked to, that in some ways represents the group, but is still particular enough  that you can think about it. Typically, not one persona, you usually have  several personas. We'll come back to that.   You use this persona description, it's  a description of the example user,   in many ways during design. You can ask  questions like "What would Betty think?"

You've got a persona called / about Betty, "what would  Betty think" or "how would Betty feel about using this aspect of the system? Would Betty understand this? Would Betty be able to do this?"   So we can ask questions by letting those personas  seed our understanding, seed our imagination.   Crucially, the details matter here. You want to make the persona real. So what we want to do is take this  persona, an image of this example user,   and to be able to ask those questions: will  this user..., what will this user feel about  

this feature? How will this user use this system  in order to be able to answer those questions?  It needs to seed your imagination well enough.  It has to feel realistic enough to be able to   do that. Just like when you read that book  and you think, no, that person would never   do that. You've understood them well enough that  certain things they do feel out of character. You need to understand the character of your  persona.

For different purposes actually, different levels of detail are useful. So I'm going to sort of start off with   the least and go to the ones which I think are  actually seeding that rich understanding.  So at one level, you can just look at your  demographics. You're going to design for warehouse   managers, maybe. For a new system that goes into  warehouses. So you look at the demographics, you might have looked at their age. It might be that on the whole that they're   older. Because they're managers, the older end. So  there's only a small number under 35. The majority  

are over 35, about 50:50 between those who are in  the sort of slightly more in the older group.  So that's about 40 percent of them in  the 35 to 50 age group, and about half   of them are older than 50. So on the whole  list, sort of towards the older end group.   About two thirds are male, a third are female.  Education wise, the vast majority have not got   any sort of further education beyond school. About 57 percent we've got here are school.  

We've got a certain number that have done basic  college level education and a small percentage   of warehouse managers have had a university  education. That's some sense of things.   These are invented, by the way, I should say, not  real demographics. Did have children at home. The people, you might have got this from some big  survey or from existing knowledge of the world,   or by asking the employer that you're  dealing with to give you the statistics.   So perhaps about a third of them have got children  at home, but two thirds of them haven't. 

And what about disability? About three  quarters of them have no disability whatsoever.   About one quarter do. Actually, in society  it's surprising. You might... if you think   of disability in terms of major disability,  perhaps having a missing limb or being   completely blind or completely deaf. Then you start relatively small numbers.   But if you include a wider range of disabilities,  typically it gets bigger. And in fact can become  

very, very large. If you include, for  instance, using corrective vision with   glasses, then actually these numbers  will start to look quite small.  Within this, in whatever definition they've  used, they've got up to about 17 percent with   the minor disability and about eight percent  with a major disability. So far, so good. So now, can you design for a  warehouse manager given this? Well,  

you might start to fill in examples for  yourself. So you might sort of almost like   start to create the next stage. But it's hard. So let's look at a particular user profile. Again,   this could be a real user, but let's imagine  this as a typical user in a way. So here's Betty Wilcox. So she's here as a typical user.  And in fact, actually, if you look at her, she's   on the younger end. She's not necessarily the  only one, you usually have several of these.  And she's female as well. Notice only up to  a third of our warehouse ones are female. So  

she's not necessarily the center one. We'll come  back to this in a moment, but she is an example user. One example user. This might have been  based on somebody you've talked to, and then you're sort of abstracting in a way. So, Betty Wilcox. Thirty-seven, female, college education. She's got children at home, one's  seven, one's 15. And she does have a minor disability, which is in her left hand. And  it's there's slight problem in her left hand.  

Can you design, can you ask, what would Betty  think? You're probably doing a bit better at   this now. You start to picture her a bit. And you've probably got almost like an image   in your head as we talk about  Betty. So it's getting better.   So now let's go to a different one. You know, this  is now Betty. Betty is 37 years old. She's been a   warehouse manager for five years and worked for  Simpkins Brothers Engineering for 12 years. She didn't go to university, but has studied  in her evenings for a business diploma.

That was her college education. She has two children  aged 15 and seven and does not like to work late.   Presumably because we put it  here, because of the children.   But she did part of an introductory  in-house computer course some years ago.   But it was interrupted when she was promoted,  and she can no longer afford to take the time.   Her vision is perfect, but a left hand movement,  remember from the description a moment ago,   is slightly restricted because of an  industrial accident three years ago. 

She's enthusiastic about her work and  is happy to delegate responsibility   and to take suggestions from the staff. Actually,  we're seeing somebody who is confident in her   overall abilities, otherwise she wouldn't  be somebody happy to take suggestions.   If you're not competent, you don't. We sort of see that, we start to see a   picture of her. However, she does feel threatened  – simply, she is confident in general – but she   does feel threatened by the introduction of  yet another computer system. The third since she's been working at Simpkins Brothers. So now, when we think about that, do you have a better vision of Betty?

Do you feel you might be in a position to start talking about..."Yeah, if I design this sort of feature, is this something that's going to work with Betty? Or not"? By having a rich  description, she becomes a person. Not just a set of demographics. But then you  can start to think about the person, design for the person and use that rich human understanding you have in order to create a better design.

So it's an example of a user, as I said not  necessarily a real one. You're going to use this as a surrogate and these details really, really matter. You want Betty to be real to   you as a designer, real to your clients as you  talk to them. Real to your fellow designers  as you talk to them. To the developers around  you, to different people. Crucially, though, I've already said this, there's not just one. You usually want several different personas because the users you deal with are all different.

You know, we're all different. And the user group – it's warehouse managers – it's quite a relatively narrow and constrained set of users, will all be different. Now, you can't have one persona for every user,   but you can try and spread. You can look at the range of users.   So now that demographics picture I gave,  we actually said, what's their level of education? That's one way to look at that range. You can think of it as a broad range of users.

The obvious thing to do is to have the absolute  average user. So you almost look for them:   "What's the typical thing? Yes, okay." In my  original demographics the majority have no college   education, they were school educated only. We said that was your education one,   two thirds of them male – I'd have gone for  somebody else who was male. Go down the list, bang   in the centre. Now it's useful to have that center  one, but if that's the only person you deal with,   you're not thinking about the range. But certainly you want people who in some sense  

cover the range, that give you a sense  of the different kinds of people.   And hopefully also by having several, reminds  you constantly that they are a range and have   a different set of characteristics, that there  are different people, not just a generic user.
