Site problems Test and Evaluation Strategy (TES) The Test and Evaluation Strategy (TES) describes the concept for Test and Evaluation (T&E) throughout the program life cycle, starting with Technology Development and continuing through Engineering and Manufacturing Development (EMD) into Production and Deployment. The TES is submitted to the OSD for approval prior to Milestone A. The TES will evolve into the Test and Evaluation Master Plan (TEMP) at Milestone B. Development of a TES will require early involvement of testers, evaluators, and others as a program conducts pre-system acquisition activities. The TES must be consistent with the Technology Development Strategy and Initial Capabilities Document . The TES should address the identification and management of technology risk, the evaluation of system design concepts against the preliminary mission and sustainment requirements resulting from the analysis of alternatives, competitive prototyping, early demonstration of technologies in relevant environments, and the development of an integrated test approach. The TES also satisfies the statutory requirement for a TDS test plan to ensure that the goals and exit criteria for the technology demonstrations are met (Section 235 of P.L. 107-314). It also provides a road map for evaluations, integrated test plans, and resource requirements necessary to accomplish the Technology Development (TD) phase objectives. A TES is developed to support the initial Milestone A decision and is replaced by the TEMP for all increments thereafter, unless a follow-on increment requires a new Milestone A decision.
