Trade study process is from SE Process Manual (SYSENG-100), and will be adopted by all Engineering disciplines.Trade Study Process
Decide where best to eat lunch on a typical workday.
Be sure to get approval of the purpose and scope of the objective from stakeholders.
Obtain agreement of decision maker on evaluation criteria and weights
Tailor criteria and weighting as appropriate.
Ensure weighting is normalized, and grading uses the same scale (good=low) and range across criteria.
Most Trade Studies will have items related to Cost, Schedule, and Performance and Risk as part of their evaluation criteria. Refer to SYSENG-100 Appendix E
0 to 15 minutes Very low impact (1)
15 to 30 minutes Low impact (2)
30 to 45 minutes Medium impact (3)
45 to 60 minutes High impact (4)
Over 60 minutes Very high impact (5)
For larger trade studies, it is a good idea to have a formal review of alternatives and criteria before proceeding with the analysis.
Use analysis techniques such as timeline analysis, CAIV, analysis of possible failure conditions, etc.
