Zero Defect programme explained through case study of the STC Valve at the Indian leading supplier, which was facing a problem of week and year punch rework of STC value, various tools and techniques for the operational and organizational descision making.

2. The ZD performance standard applies to all types of work:
1. Engineering,
2. Purchasing
3. Human Resources
4. Production
5. Clerical
6. Maintenance
and many others, in fact, all others.
It isn't just for manufacturing.

3. Parameter Six Sigma Zero Defect concept
Objective Managing Defects Preventing Defects
Key idea 3.4 DPMO Work right the first time
and every time
Associated cost Comparatively less Comparatively higher
cost
Instruments Statistical quality control
tools plus problem
solving algorithms
Continual improvement
through leadership
Performance Standards Few defects are
acceptable
No defects are acceptable
Scope Limited to quality of the
product or service
Applicable to every job in
the organisation
Comparison of Six sigma and Zero defects principles
