Controlling Change in IT Departments Using DMAIC

During a Six Sigma project at an information technology (IT) department, there are many good reasons why a process or a system needs to change. There also are a few bad reasons – bad, but unavoidable. It’s up to the…

Controlling the Process That Controls Business Processes

The same methods (Lean Six Sigma) which transformed manufacturing and transactional processes into smooth, high efficiency processes also will work in software and IT, if adapted to recognize the differences in these processes.

Core Set of Effectiveness Metrics for Software and IT

A basic-yet-powerful set of metrics gets to the heart of measuring organizational efficiency and effectiveness in software and IT organizations. These metrics also facilitate effective application of Six Sigma in software and IT organizations.

Creating a More Accurate IT Availability Definition

Although IT reported values for application availability might be numerically correct, they may not be a true representation of the situation. For more accurate predictions, use outside-in and rolled-throughput approaches.

DMAIC Case Study: Improving System Availability

A leading environmental services company used DMAIC to improve the availability of an internal software system. The goal was to reduce system downtime and reduce defect resolution time, thereby increasing return on investment and user satisfaction.

Exploring Defect Containment Metrics in Agile

While Design for Six Sigma (DFSS) and Agile software development seem to have different orientations, there is more linkage than meets the eye. Considering defect containment metrics, there is a positive tie between these two bodies of experience.

Leverage ITIL and Six Sigma Together to Maximize Outcome

The Information Technology Infrastructure Library (ITIL) Framework is a set of best practices that facilitate delivery of high quality IT services. Combined with Six Sigma, ITIL serves as a model that prompts organizations to use maximum synergy.

Objective Defect Evaluation Leads Improvement Efforts

In order to objectively analyze and take corrective action in instances where the best improvement project is not immediately visible, assigning severity, failure effect and end effect numbers to each option may help practitioners make the next move.

Optimizing Software/IT Role in a Typical Organization

In software and IT projects most failures are related to the lack of an understanding of what the customer really expects the system to do (operational requirements) and why (business results). But a program like Six Sigma can resolve many issues.
