There are a couple of roles that might need to be broken down, depending on  how exactly the work must be distributed, or assigned and tracked. For example,  is there a difference between a doctor office Nurse and a hospital Nurse? Are  there different types of roles a Nurse can play within a hospital? Medical Staff  might be too generic as well. A person who administers the epidural is not the  same as the staff member who checks the patient out.  At this point in the design, it is left as is until more information is obtained through  task design. At this point in the case design is outlined and the process of laying out the  solution overview can begin. This section describes the solution of this use case. The first part of the case is to determine the goals (or objectives) of the case. To  help understand the objective, a simplified lifecycle is depicted in Figure 18-3.  This shows the different phases that a patient goes through. With a lifecycle defined, the ability to determine outcomes might become clearer.  The following list describes the outcomes for this use case: 566  Building IBM Enterprise Content Management Solutions From End to End GLYPH<SM590000> Baby delivery GLYPH<SM590000> Early termination GLYPH<SM590000> Miscarriage GLYPH<SM590000> Adoption Figure 18-3 Patient lifecycle 18.3.1 Case goals 18.3 Solution overview Initial  Pregnancy Pregnancy Delivery Patient Lifecycle
