misperformance

Flawed task completion

Misperformance is the faulty or inadequate execution of a duty, task, or obligation.

The term appears mainly in legal and contractual contexts, distinguishing between complete failure to act (nonperformance) and doing something improperly: The contractor was liable for misperformance of the renovation work.

It implies the attempt was made but fell short of requirements.
