Decision cycle

Decision cycle: Decision cycle refers to the continual use of mental and physical processes by an entity to reach and implement decisions.

Within the United States military, a theory of an Observe–Orient–Decide–Act (OODA) loop has been advocated by Colonel John Boyd.

In quality control, plan–do–check–act is used.

In science, the scientific method (hypothesis–experiment–evaluation, or plan–do–check) can also be seen as a decision cycle.

In the nursing process, the ADPIE (Assessment–Diagnosis–Planning–Implementation–Evaluation) process is used. This has a suggested revision, in the ASPIRE (Assessment–Systematic Nursing Diagnosis–Planning–Implementation–'Recheck'–Evaluation) model, to include an additional stage—'Recheck'—in between 'Implementation' and 'Evaluation'.
