An environment must be established to enable verification to take place. The verification environment may be acquired, developed, reused, modified, or a combination of these, depending on the needs of the project.
The type of environment required will depend on the work products selected for verification and the verification methods used. A peer review may require little more than a package of materials, reviewers, and a room. A product test may require simulators, emulators, scenario generators, data reduction tools, environmental controls, and interfaces with other systems.
