Our Next Meeting is scheduled for
Tuesday, 12 September 2000 at 7:30 P.M.
William R. Bitman
from Johns Hopkins University/Applied Physics Laboratory
will be speaking on
Reuse and Maintenance Cost
at Johns Hopkins University/Applied Physics Laboratory in Laurel, Maryland
for a joint meeting with the Baltimore SIGAda Chapter
A deli tray and soft drinks will be served at 7:00 PM, the general meeting will start at 7:30 PM, followed by the program.
The Interfacing Techniques Comparison Graph visually compares applications in terms of attributes that relate to maintenance cost. Applications that have both lower coupling and lower complexity lie closer to the origin of the graph and exhibit lower maintenance cost than those that do not. This study supports the idea that compositional techniques are important for achieving these improved metrics.
The graph can be used in three ways. First it serves as a decision support tool for managers to determine whether expected maintenance savings compensate for the additional training, effort and time needed to support compositional development. Second, it functions as a decision support tool for designers and coders as they determine, for each module interface, whether to use coupled techniques or composition. The graph can help identify those situations in which the long term cost gain justifies the extra time needed for compositional design. Third, it can serve as a maintenance cost estimation tool. This study found a close correlation between predicted and actual maintenance effort.
WILLIAM R. BITMAN received his B.A. in 1972, an M.S. from Boston College in 1975, and a Masters of General Management (M.G.A.) in M.I.S. from University of Maryland in 1994. He joined the Johns Hopkins Applied Physics Laboratory in 1993. Mr. Bitman has given presentations at the Washington Ada Symposium, ACM Computer Science Conference, Conference on Industrial and Applied Mathematics, and International Conference on Software Reuse. He has served as vice president of the ACM SIGAda Baltimore chapter. His email address is firstname.lastname@example.org.
