survey-peers

Steps

1. What role does the subject fill, and at what grain?

Name the question it answers or the job it does, and the level of detail it sits at.

2. What else fills that role at that grain?

List the peers, including ones from outside the current domain. Keep every peer at the subject's grain: no parts of it, no systems containing it, no classes above it.

3. What most separates each peer from the subject?

Name one property per peer.

4. How do the peers arrange?

Place them along the one or two differences that separate them most.

5. Where are the empty positions?
