Abstract
This study describes the goals, foundational work, and early returns associated with establishing a pilot quality cost program at the Robert C. Byrd Green Bank Telescope (GBT). Quality costs provide a means to communicate the results of process improvement efforts in the universal language of project management: money. This scheme stratifies prevention, appraisal, internal failure and external failure costs, and seeks to quantify and compare the up-front investment in planning and risk management versus the cost of rework. An activity-based Cost of Quality (CoQ) model was blended with the Cost of Software Quality (CoSQ) model that has been successfully deployed at Raytheon Electronic Systems (RES) for this pilot program, analyzing the efforts of the GBT Software Development Division. Using this model, questions that can now be answered include: What is an appropriate length for our development cycle? Are some observing modes more reliable than others? Are we testing too much, or not enough? How good is our software quality, not in terms of defects reported and fixed, but in terms of its impact on the user? The ultimate goal is to provide a higher quality of service to customers of the telescope.
