What do you get when you combine a greenfield project with a brownfield project?

A stinking pile of compost.

Does anybody else compost at home? I’ve recently started considering our teams backlog like a compost pile. You need a mix of Carbon rich and Nitrogen rich products for proper compost. (Greens and browns, fruits and paper shreds). It seems like a healthy team would have a mix of features and debt reduction stories in their backlog. Am I too far off here to make the analogy work ?
