Dos and Donts of Software Process Improvement

Dos and Don ts of Software Process Improvement

Patrick O'Toole

This chapter provides an overview of CMMI-based process maturity measures and describes how maturity and capability levels are determined. It sheds insight into some practices that may heighten the probability of success for an improvement program, and others that may lead to a less desirable outcome. [1]

Many organizations perceive a correlation between the quality of their software processes and the quality of their resulting products and services. This holds true both for software development organizations and the software products they produce, as well as software support organizations and the software they maintain. A number of these organizations use a model-based approach, such as the Capability Maturity Model for Software (CMM) or Capability Maturity Model Integration (CMMI), to guide and measure their process improvement efforts.

Unfortunately, many well-intentioned organizations fail to achieve their stated improvement goals. In many organizations, the goal is stated in terms of attaining a CMMI level, rather than in terms linked directly to project performance. Process maturity is a laudable goal ”provided it leads to improved project performance aligned with the organization's business objectives.
