What is Alternatives Analysis?
Alternatives analysis is the structured comparison of different ways to achieve an objective — build vs buy vs rent, crash vs fast-track vs descope, repair vs replace — evaluated against explicit criteria before committing. It's the antidote to the first-idea trap: the option everyone anchors on is rarely examined against anything.
The output that matters is the documented "why": six months later, when someone asks why you didn't just do X, the analysis is the institutional memory that answers.
Worked example
A schedule slip offers three recoveries: crash the electrical work (+$120K, low risk), fast-track testing against commissioning (free, but rework risk on a regulated system), or descope the backup generator to phase 2 (free, needs owner approval, transfers risk to operations). The analysis matrix — cost, risk, approval path — sends the team to the owner with a recommendation and receipts instead of a shrug.
