Poor Documentation

Incompetent Tech/Engr

RAW MATERIAL MACHINING TAPPING ASSEMBLY/TEST DESIGN/APPLICATION

The Affinity Headings form the 1st Why which gets forwarded to the Fishbone Diagram

Sealing Washer

Valve Body Casting

Thread Adaptor Casting

Receiving Inspection

These Sub-Groups form the 2nd Why which gets forwarded to the Fishbone Diagram

The Contents of these Sub-Groups forms the 3rd Why which gets forwarded to the Fishbone Diagram

2 Root Causes and the Prevention Method for each, forms the 4th Why which gets forwarded to the Fishbone Diagram

Detection and Detection Weakness forms the 5th Why which gets forwarded to the Fishbone Diagram

Page 12: P roblem S olving I nnovator Team problem solving in a production Environment
Page 13: P roblem S olving I nnovator Team problem solving in a production Environment

All this data gets forwarded to the FMEA

Page 14: P roblem S olving I nnovator Team problem solving in a production Environment

5th WHY = Detection & Detection Weakness

1st WHY = Function

2nd WHY = Requirements

3rd WHY = Failure Mode & Failure Effect

4th Why = Root Cause & Prevention Method

The FUNCTION describes each Process Step in a Process

The Process Requirements generally reflect the Operating Conditions that are required for effective Process Control. The Product Requirement generally reflects the Specifications that must be achieved.

The Failure Mode is defined as the manner in which the process could potentially fail to meet the Product or Process Requirements.The Failure Effect is defined as the consequences incurred in the event of an actual Failure.

A Root Cause can be defined as a Product or Process or Design Weakness that may result in a failure.

The Detection Controls are specific actions taken to detect the Failure Mode if it happens.
