New Tool – Convergence Diagnostic Strategies
Visteon Proprietary

WHAT? Diagnosing problems using functional and structural strategies and tactics to converge to a causal explanation. HOW? Uses an effect to cause approach - start with the failure mode - and move towards root cause – the failure mechanism.

WHEN? • limited prior data • parts available • patterns identified •easily discriminated between good and bad. WHY? • rapidly identify root cause • simple to implement • focus on observed facts Avoid Speculation. • OEM request

When to Use and Not Use Convergence
Convergence Diagnostic Strategies focuses onreaching true causal explanation quickly so that problems may be fixed faster! Historical data is not available, parts are available for decomposition. Consistency in defects and process/ part variability A metric or measurement system that easily discriminates the difference btw the extremes! Root Cause Unknown Root Cause identified

Visteon Proprietary

Shainin Limited Liability Company – Founder- Dorian Shainin – Originally known as ‘statistical engineering’ – Adapted by Keki Bhote while working with Dorian Shainin at Motorola – Documented in the book: World Class Quality, Keki R. Bhote – www.shainin.com The New Science ofFixing Things – Consultant firm founded by John Allen and David Hartshorne – Use common principles of science and engineering, supported by proper statistics when called for, to help us understand how machines function, in accordance with the laws of physics – www.tnsft.com Difference between the two techniques- Shainin is company that uses trademark tools to problem solve. Convergence DiagnosticStrategies is a concept (general model) that is used along with clever tactics to diagnose and resolve problems.
