Best Practice : Workmanship Standards
Rockwell Collins has reduced workmanship variation requirements through the application of one set of workmanship criteria. The single workmanship manual has reduced costs in maintaining documentation, training and support, and provides flexibility in supporting staffing needs with a consistent skill set across the company.
Prior to 1998 Rockwell Collins maintained seven different workmanship standards that were used to manufacture commercial and military products. Each workmanship standard was maintained in separate hardcopy books that included workmanship requirements from businesses, air transport, avionics, high-performance, J-Std, MIL-Std- 2000, and commercial requirements. The different standards had minimal graphic references available for the user, and continual maintenance of the separate standards was costly and expensive. Training for employee certification to each standard and the limitation of the employees to perform work on programs requiring different standards proved to be cumbersome and non-value-added. Differing criteria called out in the multiple standards were also confusing to different users (Figure 2-5).
In 1998 Rockwell Collins established its new product-acceptance workmanship standard that included past government, military, and industry standards. Rockwell Collins also provided additional criteria to the manual that were not addressed by government, military or industry standards. In those cases where the Rockwell Collins workmanship standard differs from the MIL specification or Class-3 industry standards, the “better-than” Rockwell Collins criteria is added. The Rockwell Collins workmanship standard supports the Single Process Initiative established by the Department of Defense in 1997.
The improvement Rockwell Collins has experienced by providing one manual versus seven includes consistency in format, wording, and graphics. The increase in the number of detailed color graphic pictures, line art, and drawings in the single manual provide the user additional assistance in interpreting critical workmanship requirements. The manual is accessible via the Rockwell Collins Rweb, and Rockwell provides access to the manual to its customer to evaluate the standards. The manual is used companywide and is administered by the Rockwell Collins Workmanship Standards Committee, with member representation throughout the company.
