A State Variable Approach for Feedback Software Process Control
Department of Computer Sciences, Purdue University
A novel approach to model the system test phase of the software life cycle is
presented. This approach is based on concepts and techniques from control
theory and is useful in computing the effort required to reduce the number of
errors and the schedule slippage under a changing process environment. Results
from these computations are used, and possibly revised, at specific checkpoints
in a feedback-control structure to meet the schedule and quality objectives.
The use of a formal approach allows for automatic calibration of the model by
means of System Identification techniques. A sensitivity analysis based on
tensor product is conducted to analyze the model behavior for variations in the
parameters. Two case studies were conducted to study the behavior of the
proposed model. One study uses data from a commercial project. The outcome from
these two case studies combined with the results of the sensitivity analysis
suggest that the proposed model might well be the first significant milestone
along the road to a formal and practical theory of software process control.
Hosted by Kenneth Anderson.

The Department holds colloquia throughout the Fall and Spring semesters. These
colloquia, open to the public, are typically held on Thursday afternoons, but
sometimes occur at other times as well.

Colloquia Mailing List.
If you would like to schedule a colloquium, see
Colloquium Scheduling.
Sign language interpreters are available upon request. Please contact
Stephanie Morris at least five days prior to the colloquium.
