I edit my post to be more specific.
I wish to start using Scrum methodology, And would like to know how the Design and Scrum live together ?
In the "Old" world I would build a complete design for my application, saying exactly where each menu should be, and how many buttons it should contain.
By being so precise, I help my dev team to understand where to build reusable components (Such as a menu UI, that will be inherited by sub menus), and give them a "Big Picture" about the app.
How is this dealt with in Scrum ?
In Scrum we work by sprints, and it seems like a problem for developers to see a "Big Picture" about the app, because there is no "Big Picture", there is only the next sprint.
Thanks a lot, Michael.
