Various techniques have been used for managing software quality, including those that predict defect counts over time. This paper introduces a simulation model based on COQUALMO, which can be calibrated to organizational process performance for estimating counts of residual defects. This simulator has the additional benefit of producing a set of estimated defectivity profiles over a software development cycle. Such a set of profiles can be used to support quality management decisions regarding the amount and level of defect removal activities to be applied during a development cycle.
