In , PDCA (Plan–Do–Check–Act) is used.^[2]

In , the scientific method (Observation–Hypothesis–Experiment–Evaluation) can also be seen as a decision cycle.^[3][4]

In the , a theory of an OODA loop (Observe–Orient–Decide–Act) has been advocated by Colonel John Boyd.^[5]

In the methodology, the Build-Measure-Learn loop is used to guide product development.^[6]

In , Herbert A. Simon proposed a decision cycle of three steps (Intelligence–Design–Choice).^[7] Much later, other scholars expanded his framework to five steps (Intelligence–Design–Choice–Implementation–Learning).^[8]

In , the design process is often conceived as a decision cycle (or design cycle), such as Robert McKim's ETC (Express–Test–Cycle).^[9][4]

In the time management method, workflow consists of a cycle of five stages (Collect–Process–Organize–Do–Review).^[10]

In the , the ADPIE (Assessment–Diagnosis–Planning–Implementation–Evaluation) process is used.^[11] Alternatively, the ASPIRE (Assessment–Systematic Nursing Diagnosis–Planning–Implementation–Recheck–Evaluation) model includes an additional stage—Recheck—in between Implementation and Evaluation.^[12]

In , the transtheoretical model posits five stages of intentional change (Precontemplation–Contemplation–Preparation–Action–Maintenance). These stages were initially conceived as linear, but John C. Norcross said that for many people the stages are more appropriately viewed as a cycle (Psych–Prep–Perspire–Persist–Relapse).^[13]

In , the use of a program cycle, "codified in the Automated Directive Systems (ADS) 201, is USAID's operational model for planning, delivering, assessing, and adapting development programming in a given region or country to achieve more effective and sustainable results in order to advance U.S. foreign policy".^[14] Relatedly, within the agency there exists resources regarding adaptive management decision cycles.^[15]
