Analyses are performed to determine what impact the intended
operational environment will have on the ability to satisfy the
stakeholders’ needs, expectations, constraints, and interfaces.
Considerations, such as feasibility, mission needs, cost constraints,
potential market size, and acquisition strategy, must all be taken into
account, depending on the product context. A definition of required
functionality is also established. All specified usage modes for the
product are considered, and a timeline analysis is generated for timecritical
sequencing of functions.
