Where Are We? We have defined broad responsibilities of the

company from a functional perspective Business Areas

Each business area represents a major business activity supported by manual and automated processes

Now need to open up the business area and identify the specific activities that happen within the business area Business Use Cases

Business Use Cases Represent business processes (activities) the

company uses to satisfy the requests of business ‘actors’ (we will look into actors later)

Documented in a Business Use Case Diagram Described in a document called a Business

Use Case Specification Note: A Business Area has 1 or more

Business Use Cases

Business Use Case Represents a specific workflow in the

business – a complete sequence of steps that provides a result to an ‘actor’

automated business processes May take place over an extended

period of time

business? Actor

succeed

Identifying Business Use Cases Look for processes the company uses to

satisfy the requests of the business actors Identify the processing (manual and

automated) that happen Could be an event that the business needs to

respond to or it could be an event where the business needs to generate some kind of response back

Give the process a name Business Use Case name begins with a

verb

Identifying Business Use Cases Where does a use case start?

Look for a trigger, a commercial event Customer would like to rent a vehicle Customer would like to place a bid on eBay Clerk would like to inquire how much stock is on

hand for a specific product

Did each Business Use Case identified have an event it needed to respond to (trigger)?

Did each Business Use Case identified have a meaningful result (did it generate some kind of a response)?

Business Use Case but not always i.e. Human Resources is a business

area but there are many business processes within that business area

In some cases, you need to think of the goal of the business processing that has to take place
