The results are evaluated to assess progress of design, performance, supportability, etc. Developmental test and evaluation (DT& E) is an engineering tool used to reduce risk throughout the acquisition cycle. Operational test and evaluation (OT& E) is the actual or simulated employment, by typical users, of a system under realistic operational conditions . To be effective, testing cannot occur only at the end of a development. It must be addressed continuously throughout the entire life cycle. Test and Evaluation involves evaluating a product from the component level, to stand- alone system, integrated system, and, if appropriate, system- of- system and enterprise. Figure 1 highlights these levels of evaluation and how they align with government DT, OT, and accreditation and certification testing. Figure 1. Product Life- cycle Test Phases. The articles in this topic are arranged according to a notional V- model life cycle . As noted elsewhere in the Guide, the system life cycle is rarely, if ever, as linear as the simplified V- model might imply. MITRE SE Roles & Expectations: MITRE systems engineers (SEs) are expected to be able to create test and evaluation strategies to field effective, interoperable systems that include making recommendations on certification and accreditation processes. 2 Defense Acquisition Guidebook ANNEX TEST AND EVALUATION MASTER PLAN FOR PROGRAM TITLE/SYSTEM NAME ACRONYM ACAT Level Program Elements Xxxxx *****.

They assist in developing and defining test and evaluation plans and procedures. MITRE SEs participate in developmental and operational testing, observe and communicate test results, influence re- test decisions, recommend mitigation strategies, and assist the customer/sponsor in making system acceptance decisions. Best Practices and Lessons Learned. Employ prototypes and M& S to advantage. Prototypes and/or modeling and simulation (M& S) used early in a program can help predict system performance and identify expected results, both good and bad. Both techniques can be used in designing, evaluating, or debugging portions of a system before incurring the expense of . Use common sense in testing. For example, while it is necessary to ensure that environment testing covers the environment that your system is expected to operate in, specifying and testing a system to operate to - 7. This is an especially common pitfall when designing systems for mobile or airborne environments. Extreme temperature, vibration, radiated emissions, etc. Ensure that the tests are realistic. Match testing method with purpose. There are many forms of testing. Some involve instrumented measurements of system performance during . Others, in decreasing order of complexity, are analysis, demonstration, or inspection. Select the testing method that suits the purpose. The performance of a critical operational capability (e. Analysis is suited to testing requirements like long- term reliability of electronic components, and when assessing inspection is appropriate (e. Selecting the right verification methods produces the right results and saves time and cost. Test strategy—start early and refine continuously. Plan the test strategy from the onset of the program and refine it throughout the program's life cycle. Involve the right stakeholders in the development and review of the test strategy and plans.

Don't overlook the basics. Ensure that tests have been developed to be objective and capable of assessing compliance with a requirement. Make sure that if one test is intended to validate many lower level requirements, you are sufficiently versed with the details of the system design and have the results of the component level tests available. This is particularly important in preparing for operation testing. Ready or not? Determining suitability to enter a test is a key decision that can substantially affect the overall success of the program. Know when you are ready, and know when you are not. When unsure, postponing or deferring testing may be the most prudent long- term course of action. References & Resources. Defense Acquisition University website. Wikipedia contributors.
