Scenario and Feature Frame
A Scenario and Feature Frame is a matrix that shows incremental value and dependencies. It's a simple way to show management your baseline release, your nice to have scenarios, and your vNext planning. It's also a great way for your development team to see how their effort fits into the big picture, as well as recognize any dangerous cross-dependencies.
