Of course I agree! That diagram below is just an example for how you can fit in an actual requirement to the UX Process. So I have just used a considerably smaller freelance project where the client had provided me with enough information.

So yeah, time that will be taken to each phase will depend on the techniques we choose and the scope of each project ☺

Thank you so much for your response. It made me realize that I could have elaborated more on that.

Hopefully, I will cover those in my future article.
