STR.13:4.2 - Compare serious current alternatives
Include the current method, a feasible lighter or stronger alternative, a situation-specific branch and stopping the proposed method change where those can affect the choice. A support or capability change can be a serious rival to replacing the method.
For each alternative compare:
- the strategic result it can support and its material blind spots;
- the uncertainty and comparison basis it can represent responsibly;
- time, cognitive effort, coordination, tools and maintenance;
- required capability, access, assignments and authority;
- affected people, exposure, displaced work and reversibility;
- evidence strength, applicability limits and the remaining gap.
Keep observed performance, estimates and structural reasoning distinct. A completed workshop is not evidence that a better strategic decision followed. An adequate comparison may rely on credible estimates and constraints without pretending to have causal evidence.
Use ME.14 to return a situated keep, revise, replace, branch or stop, or a retained set with its unresolved limitation. A supported current course can coexist with an unresolved stronger claim. Further testing is selected only when its attainable decision contribution warrants the whole burden under C.11.DUA.
