Unit 10: System Conception

The purpose of elaboration is to analyse the problem, develop the project plan further, Notes
and eliminate the riskier areas of the project.

A key activity in the Elaboration Phase is the mitigation of risks. The sooner risks are
identified and shot down, the lesser their impact will be on the project.
A problem statement is a clear concise description of the issues that need to be addressed
by a problem solving team and should be presented to them (or created by them) before
they try to solve the problem.

Object-oriented analysis (OOA) looks at the problem domain, with the aim of producing
a conceptual model of the information that exists in the area being analyzed.
The result of object-oriented analysis is a description of what the system is functionally
required to do, in the form of a conceptual model.

10.4 Keywords

Conceptual model: Conceptual model allows us to capture, using UML, a graphical statement of
the customer’s problem.
Elaboration: Elaboration is the point where you want to have a better understanding of the
problem.

Problem statement: A problem statement is a clear concise description of the issues that need to

System Conception: System conception is considered as a requirement analysis phase where
requirements describe how system behaves from the user’s point of view.
