Unlike the waterfall model, the RUP does not equate phases directly with process activities. How are phases and activities related in the RUP?

Phases and workflows are the same thing described with different terminology

Phases in the RUP are more closely related to business concerns rather than technical activities — all workflows may be active across all phases

Each phase maps to exactly one process activity, just like waterfall

Phases define the technical activities; workflows define the business objectives

Correct Answer

Phases in the RUP are more closely related to business concerns rather than technical activities — all workflows may be active across all phases

Explanation

Unlike the waterfall model where phases are equated with process activities, phases in the RUP are more closely related to business rather than technical concerns. Workflows are static technical activities that are not associated with a single phase — in principle, all workflows may be active at all stages of the process.
