Producibility Element Highlighted:
Perform Trade Studies on Alternative Product and Process
McDonnell Douglas Aerospace (MDA) (St. Louis) (Boeing Aircraft and Missiles) re-engineered its trade study process to improve the product and response time to its internal and external customers. Based on a description of what should be included in a trade study, MDA (St. Louis) surveyed its high priority customers to determine further requirements for an exemplary study. Responses cited the need for such studies to be accurate, timely, objective, thorough, complete, have a consistent format, be documented, present a range of options, and provide a technical recommendation. In order to meet customer quality requirements, each Trade Study conducted within Product
Definition is expected to be characterized by a consistent set of elements which include:
- Clear problem statement
- Identification of requirements that must be achieved
- Ground rules and assumptions
- Decision criteria
- Resource requirements statement (source/man hours required)
- Schedule to accomplish (proposed and actual)
- Potential solutions and screening matrix
- Comprehensive array of feasible alternatives
- Comparisons of alternatives using decision criteria
- Technical recommendation of Trade Study Leader
- Documentation of Decisions leading to recommendation.
The MDA (St. Louis) trade study process has been thoroughly modeled and brought under a control process that ensures that studies are timely and of a consistently high quality. Scheduling planning extends down to requiring that study documents be delivered to participants before meetings to allow sufficient time to review the progress of the study results. Personnel involved in the process know what problems they are to address, who it should be coordinated with, and when they are expected to conclude the study.
