Combining Six Sigma and CMMI Can Accelerate Improvements

Capability Maturity Model Integration (CMMI) is a framework for business process improvement. Like any model, CMMI reflects one version of reality, and like most models, it may be more idealistic than realistic in some ways. Organizations can use the model as a jumping off point to create process improvement solutions that fit their unique development…

Six Sigma for Software – More Than a New Tool

We need to fundamentally change what’s going on in Software. FAST! Defects, long cycle times, poor estimation, missed targets and project cancellations are stripping away profits and our ability to satisfy and retain customers. It’s occurring in Software Development companies, Embedded Product Software (Firmware), and Business Application Software. And, it’s happening in all industry segments….

Combining CMMI, PSP, TSP and Six Sigma for Software

PSP and TSP are software development process definitions (some might call them methodologies) that are compatible with a wide range of software development concepts such as spiral development, object oriented development, and various other sets of techniques, each with certain advantages in modeling and describing requirements and designs for software systems. One way of viewing…

Objective Defect Evaluation Leads Improvement Efforts

Many times it is imperative for a firm to improve the quality of its deliverables even though it is operating consistently at a high sigma level. Such continuous improvement is also necessary when addressing various levels of the capability maturity model integration (CMMI), a software process guide. CMMI Level 5 calls for a proactive reduction…

CMMI or Six Sigma: Does It Matter Which Comes First?

An organization is getting into process improvement. Should it look at the Software Engineering Institute’s capability maturity model integration (CMMI) first? Six Sigma first? Or both at the same time? This dilemma has confronted many organizations during the last several years. The situation reminds me of a session at a symposium in 1984 at which…

Calculating Sigma Level for Project Planning Process Area

Following the implementation of Capability Maturity Model Integration (CMMI) at Level 5 in an organization, the normal practice is to measure the metrics for each process area and report it to top management. The overall performance of the organization in terms of a specific process area is not measured in most cases. A single performance…

Roadmap for Integrating ITIL, CMMI and Lean Six Sigma

Several documented approaches are available for business and IT leaders to use when considering implementing the best practices of the Information Technology Infrastructure Library (ITIL), or the Software Engineering Institute’s capability maturity model integration (CMMI) or Lean Six Sigma as individual methodologies or frameworks. There also are some references that suggest how to use the…
