2、l Abstract: NGLT experienced continual disagreement over processes, procedures and products to be used by the Programs SE&A teams, all of which came from different legacy programs, each possessing different requirements and Center perspectives (e.g., search versus development). Programs should defin
3、e, plan, and agree to processes, procedures, and products for the SE&A process as early as possible and formally document in a SEMP. Description of Driving Event: NGLT experienced continual disagreement over processes, procedures and products to be used by the Programs SE&A teams, all of which came
4、from different legacy programs, each possessing different requirements and Center perspectives (e.g., search versus development). For example, inconsistencies in weights and sizing models and differences in definitions of subsystems, combined with insufficient technical exchange with the various arc
5、hitectural teams, led to incorrect interpretation of data, and inaccurate and/or misleading results that required rework. Lesson(s) Learned: An agreed-to set of processes, procedures, and products, documented in a base-lined and approved Systems Engineering Management Plan (SEMP) would have greatly
6、enhanced the effectiveness of the systems engineering and analysis teams. The SEMP should have been the first item addressed by the SE&A leadership to create a common understanding of definitions, methods, and processes to be utilized.
