Mechanics of Structured Analysis

In the past section we discussed extended notation and basic for structured analysis.  To be used efficiently in software requirements analysis this notation must be combined with a group of  heuristics which enable a software engineer to derive a good analysis model  to describe the use of these heuristics an adapted edition of the pirbhai and hatley extensions to the basic structured analysis notation will be used by the remainder of this lecture.

In the part that flow we examine each of the steps which should be applied to established accurate and complete models using structured analysis.  By this discussion the notation introduced will be used and other notational forms alluded to previously will be presented.
