Claims processing: organizing data groups.
The consolidation step is intended to organize the collected requirements in a
way that would make sense and be useful for the design phase. So what are the tasks
in this step? Let us say that you have collected requirements from the interviews
with the users in the claims processing unit and also gathered requirements by study-
ing the screen formats and the report layouts of the claims processing application.
You would have collected most of the information through the interviews and addi-
tional information through the study of the screens and reports. How do you con-
solidate and record what you have collected? Figure 4-11 illustrates the method for
organizing the information collected and recording these by business objects.
Observe how the data groups are formed for the process of settling claims.
The outcome of this step is the organized data groups. Each data group relates
to a single business object, and each data group has been derived from the infor-
mation gathered for a single process through the standard methods.
Requirements Definition Document
Publishing a requirements definition document signals the end of the requirements
definition phase. The analysts combine all the information collected through dif-
ferent methods and prepare the document. After a draft is prepared, it must be
reviewed and confirmed by the users. This is absolutely essential to ensure that you
have not overlooked any data requirement. Also, the review and confirmation task
corrects any misunderstandings and clarifies ambiguous requirements.
Here is a suggested outline for the requirements definition document. Amend
and adapt the outline to suit your database project.
