“Prevention is better than cure” applies to defects in the software development life cycle as well as illnesses in medical science. Defects, as defined by software developers, are variances from a desired attribute. These attributes include complete and correct requirements and specifications as drawn from the desires of potential customers. Thus, defects cause […]

This article describes the successful implementation of a Six Sigma Green Belt project in information technology (IT) in which a software development team applied Six Sigma to reduce the resolution time of software defects and minimize rework, thereby increasing customer satisfaction. A software development team in a leading environmental services company wanted to reduce the […]

An information technology (IT) services company was engaged by a European telecom service provider to provide end-to-end testing for its five lines of business. End-to-end testing is a methodology used to test whether the flow of a software application is functioning as expected from start to finish – for example, from receipt of customer order […]

The Lean Six Sigma (LSS) toolbox can always be extended with new approaches that enable the harvesting of new opportunities for improvement. Philosophically, improvement in terms of velocity, cost, quality, performance, reliability and widespread customer acceptance remain relevant but also complex. One way of extending the use of these methodologies and tools is by developing […]

Inspections are one of the most common methods of review performed in software teams. The goal of code inspection is to identify software faults early in the software development lifecycle. Teams are faced with the challenge, however, of determining whether those inspections are effective. One way to quantify this is by predicting the total number […]

Computacenter AG & Co. oHG, an information technology (IT) services firm that first began its Six Sigma deployment 14 years ago, has made its second consecutive appearance on iSixSigma’s Best Places to Work list. Computacenter was ranked at No. 10 for this year’s list, the same position it was given in the 2010 list. The […]

This step-by-step guide shows how Belts in the transactional sector can calculate the time needed to complete a process and utilize their resources efficiently.

What is Scrum and how can it help you in your Lean Six Sigma efforts? That was the topic of a breakout session presented by Brad Zylstra of Volt Information Services on Tuesday, Feb. 8, at the iSixSigma Live! Summit & Awards in Miami. Zylstra, the Vice President of Strategic Business Services and Support at […]

As the calendar flips to 2011, several technology experts and software providers have made predictions about how Lean Six Sigma and other process improvement methodologies will shape IT departments in the coming year. Collected here are four of their forecasts for the next 12 months.

Lean Six Sigma projects involving software development are an increasingly popular option for IT departments that are seeking to improve their efficiency. However, a number of research studies demonstrate that the average percentage of software projects that achieve all project objectives is significantly less than might be expected. For instance, a Standish Group survey conducted […]

Scrum is an Agile project management methodology that can be used to control software and product development using iterative, incremental practices. Scrum generates the benefits of Agile development with the advantages of a simple implementation. This methodology can significantly increase productivity and reduce time to benefits while facilitating adaptive, empirical systems development.

By mapping the entire software application development life cycle, IT departments can see dramatic improvements in efficiency.

One of the initial challenges of enhancing IT quality metrics is to manage the mountain of data produced at a typical organization. Those organizations that have not learned how to mine their existing information to find solutions tend to track their data via spreadsheets and then generate high-level reports for executive management. Often, major gaps […]

Software and IT experts discuss the best ways that methods such as business process managment and Agile can be applied to a Lean software development program.

When facing an imminent layoff, what path should Six Sigma professionals with a technical background take to get into the information technology (IT) arena? This topic was brought up in a recent online conversation on the iSixSigma Discussion Forums. The suggestions included getting familiar with the capability maturity model (CMM), joining an IT organization, becoming […]

The gains that Lean Six Sigma has brought in the areas of manufacturing, operations and physical product design speak for themselves. It is natural to want to replicate that success in software design. To do that most effectively, however, practitioners must meld Lean Six Sigma with Agile, a software development technique that is gaining traction […]

The demand for business intelligence continually increases. Tapping into predictive analytics, a type of data mining that can be used to make reliable predictions of future events based on analysis of historical data, can help.

Parts one and two of this series surveyed the work connected with several goals shared by software organizations and Six Sigma (Goals 1-3 in Table 1). We saw that reaching those goals involved establishing systems to identify defects, classify them according to type and point of origin, predict their occurrence, and assess actual defect find […]

This article is the last of four parts. It presents a discussion of opportunities for defects (OFD), defects per million opportunities (DPMO) and Sigma levels. When comparing implementations across companies, using the common language of DPMO and Sigma levels will assist in understanding benchmarking data. Parts one, two and three followed a progression of goals […]

Two recent conferences on software focused on the topics of Six Sigma for the software industry and general conference for the software vertical market. There was, as one would imagine, a tremendous amount of discussion relating to the offshore outsourcing of software development work to achieve significant cost reductions. This has been an emerging trend […]

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. […]

I’m sure we are all happy to see the new iSixSigma channel dedicated to software. The growing knowledge base at this portal will take shape in the body of articles, discussion forum threads, links, and resources that are contributed. The most important factor in all this is, of course, you, the site participants. While the […]

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 […]

The following advice should help clarify your thinking about software testing and help you improve the effectiveness and efficiency of your testing. It is helpful to think about software testing in terms of five essential elements: A test strategy that tells you what types of testing and the amount of testing you think will work […]
