Many analysts skip the identification of business processes and move right to the Use Cases. Some call these “Business Use Cases” and view them as logical, business requirements. I recommend that both business processes and system Use Cases are important components. They are two different requirement constructs representing two different perspectives with two different purposes.
|Business Process||Use Case|
|business area perspective||actor or use perspective|
|business activity or need||software function|
|independent of technology||describes the behavior of the technology|
