Best Practice : Technical Manufacturing Data Package
The Engineering and Operations group of Raytheon Integrated Defense Systems merged two processes to reduce both cycle time and defects – the design process that produced the Technical Design Package and the manufacturing process that produced the Manufacturing Design Package. Through co-authored, co-released and co-managed designs, more complete information is available at the beginning of the Technical Manufacturing Data Package process to produce fewer changes.
The transition to production of new electro-mechanical designs was a serial process with many hand-offs. In the legacy process, the Technical Data Package (TDP) and Manufacturing Data Package (MDP) are created, managed, and maintained in separate systems and databases. This process resulted in long cycle times and significant opportunity for errors as a result of interpretation and transposition issues.
The Technical and Manufacturing Data Package (TMDP) process was introduced to create and enable an environment where the common TDP and MDP data are contained in a single database. This data is co-authored, co-released, and co-managed by mechanical design and manufacturing engineering. TMDPs are currently executed on new Pro-E-designed microwave, electromechanical and antenna integration assemblies where the drawings include preferred assembly sequence, basic “what to” instructions, and application views. Proprietary and manufacturing specific “how to” processes are defined and managed outside of the TMDP.
The combined TMDP document increases Raytheon’s “No Doubt Mission Assurance” that a product’s design intent is captured in the manufacturing process, dramatically improving the connection between design and manufacturing through the use of one database, one data package, and one process across multiple programs. This has institutionalized concurrent engineering and lessons learned throughout the life of the data package, compressed product and process development cycle times, and produced a significant reduction in out-of-phase defects resulting in earlier defect containment and associated benefits.
