G-C-E-C-P-C methodology of root cause elimination

The G-C-E-C-P-C methodology of root cause elimination is part of a statistical "tool set"
called "Structured Improvement with Strategy" used for business process improvement and training
for process engineers, process owners and process developers.
;G...Get Data: Measure, Monitor, Record,......
;C...Compare Data: Perform comparison between defined, specified,standardized information or measurement values (comparison between: instantaneous value; actual value & set point value; specified value)
;E...Evaluate / Analyse / Trace: Evaluate all measured or recognized deviations (anomalies, irregularities) in a systematic and structured way.
;C...Correct: the largest found issue at first
;P...Perform:Perform a “new” test run:
;C...Control:Keep your applied action under tight and careful control and check how the process, machine,… responds to your applied action.
The cycle, starting from G have to be repeated step by step,
until the root cause is eliminated.
It is explained very clearly that there is the basic need to understand the
difference between a symptom and a problem and how to define what a syptom is and what a problem is.
To understand that a high scrap rate is a symptom and not the problem for the technicians, that
is one key aspect.
The idea behind is, to understand that sometimes a change is an improvement and sometimes a change
is called improvement and a so-called improvement is just a change and the success is temporary and might be
only the sum of all done experiments.
The alleged and short-term success is simply the sum of all experiments and
not reproducible and repeatable.
If the problem can be reproduced, and the same symtoms are shown again, then the root cause is found.
Symptom - Cause - Effect - Involvement - Affect
