[Research&Study] differences between real user & persona

When we did user research, 
We ask their behavior in real situation and find out their needs and goal.
So we used to make a form to compile user's apply
like this 

But after we find out real user's problem and set some functions according to user needs, 

WHAT IS NEXT STEP?

Of course, There is no exact answer in this question.
But to follow design thinking process, 
maybe next step is making PERSONA 
like this

WAIT! I've seen before .

OMG, WHY WE HAVE TO DO THIS AGAIN?
We already find out user's need and goal. 
why we have to make fake person? we already get some idea from real person !! 


BECAUSE OF THIS FOLLOWING REASONS

1. Think objectively
If you make persona, you can assume many kinds of situations and personalities.
then you will have a lot of cases. so you can think many cases(users) and your idea will be more objective.

2. Assumptions- Fictional, fake characters and profile, 
but can based on user interview result
Persona is fake character. but we need to narrow down the number of characters.
It is not only you cannot make whole persona all over the world but also You can lose a destination and fall in a different way. so we have to make persona based on our user interview results like 'user story'(the word 'user story' is used many steps in UX, in my words it is real user interview before make persona)

3. Make your product user-oriented

4. Imagine context, story
Persona is fake person. So you need to imagine being like him(or her).
In this process, you will find invisible problems that couldn't find out at 'user story'
And you can change your perspective from you to user. then it will be good to make user-oriented product. In addition you can find out your keywords, key visuals and even promotion idea to your product

5. interview Personas are good with tight schedules 
and an overall estimated budget, and more flexible.!





Conclusion

Extension from user interview = persona
