Let me tell you the secret that has led me to my goal.
My strength lies solely in my tenacity.
The research in this thesis follows the ``Industry as Laboratory'' approach . The
GoalBased Requirements Analysis Method (GBRAM) and the GoalBased Requirements
Analysis Tool (GBRAT) were developed by applying them to their own development as well
as to other projects. The GBRAM evolved as a result of the refinements assembled from
applying the method to the experiences detailed in Chapters 3 and 6 of this dissertation.
In the first case study, goal decomposition and scenario analysis were applied in the context
of Business Process Reengineering , demonstrating that both scenario and goal analysis
are valuable for an effective analysis effort. The GBRAM was then evaluated by applying
it to the requirements analysis of a continuing education system  and subsequently to
the meeting scheduler system. Further validation of the method was sought by applying
it to construct the requirements for a tool to support the method; this effort led to the
design and implementation of the GBRAT prototype . Through these various case stud
ies, the method was evaluated and evolved based on the experiences and lessons learned.
However, it was also necessary to reason about the scalability of GBRAM to larger com
