Compare future effort, switching horizons and stated preferences.
Compare future options without charging sunk effort twice
Keep the historical ledger while comparing effort that can still change.
Compare a flexible design using conditional later effort
Show where paying more now can reduce modelled expected effort later.
Find the remaining-use horizon that justifies a method switch
Solve the equality before applying a lower recurring effort claim.
Check whether an effort range makes one option always cheaper
Use permitted counter-scenarios before ranking uncertain options.
Record the preference threshold that changes an option ranking
Make a weighted choice conditional rather than disguising subjective weights as facts.
