Determine when a solution is sufficient by distinguishing essential quality from perfectionism and diminishing returns. Use when: (1) asked to evaluate whether a solution meets requirements or needs additional work, (2) code that already meets requirements is receiving polish without an identified functional deficiency, (3) sufficiency criteria for the current solution are not clearly stated, (4) phrases like "just in case" or "might need later" appear without connection to actual requirements.
