2、to reduce total mission cost. However, the impact of undefined interfaces at the start of the contract and the uncertainties related to government-furnished hardware, resulted in some costs, which could have been avoided. Additional cost savings could have been realized if the instrument design and
3、other interfaces were in a more advanced state.Lesson(s) Learned: Fixed price spacecraft contracting works best when interfaces are well defined. Since the design of the spacecraft (and other mission elements) revolves around the instruments design and function, it is crucial that the concept, requi
4、rements, technology, design and engineering model will result in open-ended support requirements and numerous contract/cost/schedule changes throughout the implementation phase, which reduces the efficiency of the initial bus procurement.Recommendation(s): Delay finalization of the spacecraft until
5、interfaces are defined to a reasonable confidence level, so as not to significantly impact spacecraft configuration or the fixed price, OR proceed with a study period with multiple competitors until interfaces are sufficiently defined, with down-selection and final price determination occurring at t
6、he end of the study period. Additionally, limit the contribution of government furnished equipment to those items that “make sense.“ If the contractor can provide the equipment at a reasonable cost and risk, include it in the fixed price contract; this will minimize impacts to the fixed price effort
