Overlaps & Gaps, Similarities and Differences • Identify Overlaps • If two components are similar, put them closer together. • If different, farther apart. • Is anything missing? Are you sure? • Look for hidden assumptions
Opportunities and Variations • What’s the low hanging fruit? • Successes? Failures? • What Variations are OK? Not? • How long will it take to fix?
