QAT Categorisation Based on Risk Management Process
Most prior research has focused on techniques for individual quality attributes or
specific lifecycle phases. We are attempting to provide a more general framework
for QATs, using risk management as a general theory for managing quality during
development. We have found risk management to be useful in understanding
how QATs function to affect quality by identifying, analyzing, and controlling
potential quality problems. In the QATF, categories classify QATs according
to the method by which they address quality risks. We believe this will help
process engineers to incorporate appropriate QATs to better manage quality
throughout the development process. For example, FMEA is useful for hazard
analysis (safety risk analysis). Process engineers may include FMEA into process
activities which require hazard analysis during the design phase.
According to [25, p.7], the risk management process is “a continuous pro-
cess for systematically addressing risk throughout the life cycle of a product or
