Scope choices under constraints
Compare complete feature sets, incremental benefit and coverage tradeoffs.
Remove a dominated scope option before choosing tradeoffs
Compare effort and supplied benefit points without inventing a weighted score.
Choose a whole feature subset within an effort limit
Compare feasible subsets rather than fractional features.
Compare the value of additions to an already planned baseline
Avoid crediting an extension for benefits already supplied by the baseline.
Find the least-effort set covering all required capabilities
Use set coverage when overlapping features do not earn duplicate coverage.
Compare scope by its worst supplied scenario
State a worst-case objective rather than inventing scenario probabilities.
