1.The Right Decision

Deductive Closure

To make the RIGHT Decision

A Deductive and a Direct Conclusion

1.Activities not for decision making or of what don't have to be decision decision

2.Reliability is the likelihood of an objective to be achieved for a product to function satisfactorily in field.

2.Decisions and Logics

1.Decisions per sufficiency based on Evidence

2.Decisions per Sufficiency based on Assumption

-one time effort, no fact available: risk management needed to collect and gain experience, lessons learnt

-probability used and appropriate for evaluations:

(see Anderson-Cook, Christine M. “Let’s Be Realistic: Strengthen Decision Making with Formal Structure.” Quality Progress, Mar. 2013, pp. 52-54. Also see "Try this Method to Help with Complex Decisions (DMRCS)")

2.Decisions based on Hypothesis testing

3.Examples of Decisions

Decisions per Sufficiency

Specific individual without variation. the result is one time and certain (Note: in an RCM case, the subject is specific but maintenance can be multiple and results can vary). it either has happened or yet to happen with only one certain result. some examples include:

1.Daily life: do we need to take the baby to the hospital?

-Criteria essential: whether it is in an emergency condition?

-Work in phases: call a doctor first before making the decision say.

-Sufficient to determine it's an emergency condition:

-If not sufficient: then decide per else.

2.Personal: do I need to change groups for a better career opportunity?

3.Military actions: can the convoy ride and pass the bridge safely without the bridge possibly collapsing?

4.Criminal justice:

-Must sufficient: procedural justice, innocence presumption

Intermediate Decisions
