PSDA.4:2 - Problem

A popular method can be well described and still be wrong for the current inquiry. It may require participation that cannot be obtained, assume a shared purpose that is disputed, depend on data that do not exist, or produce agreement when the recipient actually needs competing claims and discriminating evidence.

Combining methods creates further risks. A concern map becomes numerical weights without an elicitation basis. A scenario becomes a probability distribution. Two workshops duplicate the same task while an essential technical question remains unanswered. A schedule of activities is called an integrated Method even though no one can explain what connects its results.
