STATISTICAL PROCESS-CONTROL FOR SOFTWARE IN THE MAINTENANCE PHASE

As technology advances and our dependency on software increases, the r equirement to develop the correct means to improve quality in both the deveiopment phase and the maintenance phase of software life cycle su pport becomes increasingly significant. The focus of this paper is on the dilemma facing software engineering in maintaining quality within the constraints of the maintenance phase. The paper further proposes t hat the software maintenance process can also be analvzed and improved using statistical process control (SPC) techniques. The methods discu ssed in this paper have been proposed for use in the Software Maintena nce project at NUWC Detachment Norfolk. Upon successful testing at NUW C Detachment Norfolk, they will be forwarded to the AN/SQQ-89(V) (inte ragencv) Software Quality Evaluation Committee for use by other agenci es which are developing and maintaining AN/SQQ-89(V) software.
