Work products are selected based on their contribution to meeting project objectives and requirements, and to addressing project risks.
The work products to be verified may include those associated with maintenance, training, and support services. The work product requirements for verification are included with the verification methods. The verification methods address the technical approach to work product verification and the specific approaches that will be used to verify that specific work products meet their requirements.
Examples of verification methods include:
Selection of the verification methods typically begins with involvement in the definition of product and product-component requirements to ensure that these requirements are verifiable. Re-verification should be addressed by the verification methods to ensure that rework performed on work products did not cause unintended defects.
