Problem: The problem or condition needs to
be returned to a prior condition or standard.
Solution: Root cause analysis (RCA) is
about taking corrective actions that get a situation back to the way it
was, plus preventing it from ever happening again. RCA uses this four step process.
Step
1: Define the problem situation that needs analysis or fixing.
Step
2: Perform a root cause analysis to find problem source.
Step
3: Develop corrective actions to fix the problem.
Step
4: Create a corrective action plan and a systems feedback process.

Problem
(Normative) Statement: States the existing condition that
needs restoring.

|
Go
|
Past or
Standard Data: Identifies the facts, as
they really existed in the past.

Deviation
Analysis: Describes the deviation from a previous
state or condition.

Transient
(Change) Description: Describes how the current
problem came into existence.

Root
Cause Analysis Questions: Questions to
determine a problem source (root cause).

So What Test: Analyze
“what if” the problem was not fixed.

Fix-It Approaches: Determine what kind of “corrective
action” is best.

Failure
Mode and Effect Analysis (FMEA):
Problem elimination tool that identifies actions to take to stop failures
before they occur.
