  • 1. Root cause analysis
  • 2. Also known as fish-bone diagram
  • 3. FICCI CE 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.
  • 5. Possible root causes for non conformance/ defects
  • 6. FICCI CE Machine factors • Inadequate process capability • Incorrectly designed tooling • Poor maintenance • Equipment effected by environmental factors such as heat, humidity etc.
  • 7. FICCI CE Material factors • Use of untested materials • Mix-up of materials • Substandard material accepted on concession because of non- availability of correct material • Inconsistency in specifications on the part of vendors
  • 8. FICCI CE Men factors • Incorrect knowledge of setting up machines • Undue rush by the operator to achieve quality targets • Lack of understanding of drawing instructions relating to a process • Operator does not posses requisite skill for operating machines
  • 9. FICCI CE Method factors • Inadequate process controls • Non availability of proper test equipments • Test equipment out of calibration • Vague inspection/ testing instructions
  • 10. Cause and effect diagramCause and effect diagram (also known as ishikawa diagram orfishbone diagram) is an analysis tool to analyze many potential oractual causes of a problem in a systematic way. It is a veryeffective way of improving the quality of the product or service.
