Abstract

Finding a balance between the time-to-market and quality of a delivered product is a daunting task. The optimal release moment is not easily found. In this chapter, we show how to utilise historical project data to monitor the progress of running projects. In particular, from the data we inferred a formula providing a rough indication of the number of defects given the effort spent thus far. Furthermore, we have investigated at a common distribution used to predict the distribution of the number of change requests over the lifetime of a project, the Rayleigh model, and whether this model is useful at Philips Healthcare to monitor the progress of a project and help decide when the product reaches a predetermined level of quality.

Notes

  1. 1.

    The Functional Clusters form a high-level decomposition of the software archive, similar to more well-known concepts such as subsystems.

  2. 2.

    In reality, critical and major defects must all be resolved before Philips Healthcare MRI releases a new version of its software.
