Root cause analysis
In any organization numerous problems exist in all facets of its
activities. The efficiency and survival of the organization
depends on how promptly these problems are recognized and
their root causes are isolated and eliminated.
4. FICCI CE
Root cause analysis
A systematic analysis of each potential problem area should be
carried out to recognize the root causes which are responsible for
creating the problem. Such analysis is called Root Cause
Analysis.

10. Cause and effect diagram
Cause and effect diagram (also known as ishikawa diagram or
fishbone diagram) is an analysis tool to analyze many potential or
actual causes of a problem in a systematic way. It is a very
effective way of improving the quality of the product or service.
