An approach that involves both automatic and human interpretation to c
orrect the software production process during development is becoming
important in IBM as a means to improve quality and productivity. A key
step of the approach is the interpretation of defect data by the proj
ect team. This paper uses examples of such correction to evaluate and
evolve the approach, and to inform and teach those who will use the ap
proach in software development. The methodology is shown to benefit di
fferent kinds of projects beyond what can be achieved by current pract
ices, and the collection of examples discussed represents the experien
ces of using a model of correction.
