Question:
It is reported that the late Bill Smith, the originator of the Six Sigma program at Motorola, had found that if a product was found defective and corrected during the production process, other defects were bound to be missed and found later by the customer during the early use of the product. However, when the product was manufactured error free, it rarely failed during early use by the consumer. This correlation between internal and external failures is a very interesting observation. Even defect detection and corrections is insufficient. Thus, to effectively reduce the often large external quality cost, rework is not sufficient. Instead, we will need to find the root causes for defects and develop genuine defectprevention programs.
Critically appraise this statement and identify key tools used in the analyse phase of the leansix sigma process to find the root causes of defects under the following four headings:
ValueStream Analysis.
Analysing sources of variation.
Determining process drivers, and
Consensus building.
