One way to show change on a project is with the Before and After shot.

before

after

You might do this if you inherit a project and you discover it’s bigger than the sponsors originally thought. Or after doing an inception deck and you discover some stuff that was originally missed.

The nice thing about this picture is it’s highly visible or colored. Red can mean new, or bigger than we thought. And the new number at the bottom quickly quantifies the difference and hopefully resets some expectations about what this project is going to take.
