Method and system of confidence scoring
First Claim
1. A method of developing, a confidence level using six sigma prediction scoring comprising:
- determining a customer expectation value;
determining a Z factor comprising a set of factors;
selecting said set of factors;
generating respective data sets for said set of factors;
collecting said respective data sets in at least one scorecard;
calculating at least one Z score for said at least one scorecard;
generating a total Z score as a function of the respective scorecard Z scores scorecards;
comparing said total Z score for said scorecards with a selected Zst value;
calculating a Z confidence range;
scoring a confidence level based upon said Z confidence range and said total Z value; and
reporting said confidence level.

Abstract
A method of developing a confidence level in reliability or producibility prediction scores that includes generating data for a set of factors, inserting the data into scorecards and dashboards, and calculating an overall Z score and Z confidence range. The scorecards and dashboards are used to calculate the confidence level in reliability scores. Each reliability or producibility factor may be weighted as to its importance to the overall confidence level. Factors included in the method include accuracy of the critical to quality flowdown; completeness of the critical to quality flowdown; percentage of the design analyzed; comprehensiveness of the design analysis; risk assessment analysis; percentage of component. subassembly or product reuse from other projects; percentage of the design complete; verification of the process capability; plant integration; order to remittance process integration; extent of pilot run; and effectiveness of a test plan.
