The W-model is a process model for the software development. It is based on the wide-spread V-model. With the W-model the test activities are accomplished parallel to other development activities (requirement definition, functional and technical system design, component specification). Test activities begin at project start and dependences and cycles between »test - debugging - correction - re-test« become clear in the W-model.
