2、echnical authority. New programs should establish a systems engineering and integration role with the authority to integrate all program elements. Description of Driving Event: Failure to quickly/clearly charter and mobilize a strong centralized technical authority.Lesson(s) Learned: Failure to quic

Additionally: a. Systems Engineering and Integration
4、Authority. The Space Launch Initiative (SLI) program was well grounded with a credible, authoritative Systems Engineering and Integration (SEI) organization. SEI was slow to mature in OSP, partially because we thought we knew what we were doing since we had transformed from SLI.b. Unfair Trades. Gov

The trade studies for smart buyer, requirement feasibility and requirement validation were initially unintegrated. Recommendation(s): Establish a Systems Engineering an

For areas involving key NASA assets or capabilities, NASA should request the contractors to work with NASA in performing joint trade studies. The final assessment and decision should be made by NASA alone, b

A horizontal integration team (HIT) should be organized up-front to develop the trade process based on accepted systems engineering practices. Evidence of Recurrence Control Effectiveness: N/ADocum
