The pre-procurement phase combines the EEE parts state-of-the-art analysis, risk analysis and component ownership cost optimization with regards to the mission requirements, design criticality and budget. In order to achieve this, the project manager leading a multidisciplinary team must find the optimal balance between component information availability (traceability, materials, testing, previous use…) and minimum tests to perform, reaching an acceptable level of reliability covering the technical, schedule and costing constraints.
