This is my favorite part of a project. Creating a visual Scope Diagram helps you personally clarify what work you’ll need to do (eyes wide open) and allows you to share with others the magnitude of the project they’ve asked you to do.
Imagine your boss asked you to oversee the United Day Way of Caring in addition to your other responsibilities. You create this Scope Diagram to make sure you’re synched-up with what her expectations are. When you show it to your boss, she says “Wow, I had no idea it would take this much effort – let’s skip it this year.” Visual scope is the best way to communicate the size of the project to the other stakeholders, specifically the Sponsor.
