Validate requirements to ensure the resulting product will perform as intended in the user's environment.

Requirements validation is performed early in the development effort with end users to gain confidence that the requirements are capable of guiding a development that results in successful final validation. This activity should be integrated with risk management activities. Mature organizations will typically perform requirements validation in a more sophisticated way using multiple techniques and will broaden the basis of the validation to include other stakeholder needs and expectations.

Typical Work Products

1.    Record of analysis methods and results

Subpractices

1.    Analyze the requirements to determine the risk that the resulting product will not perform appropriately in its intended-use environment.

2.    Explore the adequacy and completeness of requirements by developing product representations (e.g., prototypes, simulations, models, scenarios, and storyboards) and by obtaining feedback about them from relevant stakeholders.

Refer to the Validation process area for information about preparing for and performing validation on products and product components.

3.    Assess the design as it matures in the context of the requirements validation environment to identify validation issues and expose unstated needs and customer requirements.
