Fifteen teams recently used the WinWin
Spiral Model to perform the system engineering and architecting of a
set of multimedia applications for the USC Library Information
Systems. Six of the applications were then developed into an Initial
Operational Capability. The teams consisted of USC graduate students
in computer science. The applications involved extensions of USC's
UNIX-based, text-oriented, client-server Library Information System
to provide access to various multimedia archives (films, videos,
photos, maps, manuscripts, etc.).
Each of the teams produced results which
were on schedule and (with one exception) satisfactory to their
various Library clients. This paper summarizes the WinWin Spiral
Model approach taken by the teams, the experiences of the teams in
dealing with project challenges, and the major lessons learned in
applying the Model. Overall, the WinWin Spiral Model provided
sufficient flexibility and discipline to produce successful results,
but several improvements were identified to increase its
cost-effectiveness and range of applicability. |
