The results are evaluated to assess progress of design, performance, supportability, etc. Testing is a mechanism to assure quality of a product, system, or capability e.
Testing Object-Oriented Systems
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.
As noted elsewhere in the Guide, the system life cycle is rarely, if ever, as linear as the simplified V-model might imply. They assist in developing and defining test and evaluation plans and procedures. Both techniques can be used in designing, evaluating, or debugging portions of a system before incurring the expense of "bending metal.
Common sense—sometimes a rarity. Use common sense in testing. This is an especially common pitfall when designing systems for mobile or airborne environments.
Why is Assessment Important?
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 "live" operations. Others, in decreasing order of complexity, are analysis, demonstration, or inspection.
What Do We Mean by Testing, Assessment, and Evaluation?
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.
Best Practices and Lessons Learned
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.
