Analyze requirements to balance stakeholder needs and constraints.

Stakeholder needs and constraints can address cost, schedule, performance, functionality, reusable components, maintainability, or risk.

Requirements are analyzed to determine whether they reflect an appropriate balance among cost, schedule, performance, and other factors of interest to relevant stakeholders. Models and simulations can be used to estimate the impacts that requirements will have on these factors. By involving stakeholders from different phases of the product’s lifecycle in analyzing these impacts, risks can be determined. If the risks are considered unacceptable, the requirements may be revised or reprioritized to improve the balance of cost, schedule, and performance.

Typical Work Products

1.    Assessment of risks related to requirements

Subpractices

1.    Use proven models, simulations, and prototyping to analyze the balance of stakeholder needs and constraints.

Results of analyses can be used to reduce the cost of the product and the risk in acquiring and using the product.

2.    Perform a risk assessment on requirements and design constraints.

Refer to the Risk Management process area for more information about performing a risk assessment on customer and contractual requirements and design constraints.

3.    Examine product lifecycle concepts for impacts of requirements on risks.
