Six Sigma is a powerful improvement program that started in manufacturing but has subsequently proven to be useful in a multitude of industries, including software development. But many of the assumptions and approaches of using Six Sigma in traditional industries may not be relevant in information technology (IT) and software development. Traditional Six Sigma program […]

Several information technology (IT) metrics can be developed on the basis of best practice frameworks such as capability maturity model integration (CMMI) and information technology infrastructure library (ITIL). Measuring and collecting such data, which is often part of process improvement initiatives, brings to light what is happening in IT processes. Following are a few tips […]

A case can be made for using cost-of-quality metrics, combined with defect data, as overall measures of software and IT organizational effectiveness (Figure 1). The next logical step is to illustrate how these metrics might be used to drive improvement. The illustration can best be made with a “case study” of the famous-but-mythical software and […]

Although the application of Six Sigma in software development is more frequently discussed, the methodology also can be applied to software implementation projects as well. Those familiar with software implementations know that they seldom go as planned. Delays are common, cost overruns are endemic and failures are frequent. Why is this so common? What can […]

During the last 35 years, software development and technology processes in general have evolved at a rapid, even chaotic, rate. These processes range from small, Lean, agile (sometimes labeled iterative) development pockets to large, bureaucracy-laced legacy projects of tremendous scope (sometimes labeled waterfall development) and everything in between. Many organizations have undertaken attempts to classify, […]

Information technology (IT) organizations increasingly are under pressure to improve their service and process capability. In the quest for improvement methodologies, organizations often adopt a “pick one” strategy – with Six Sigma being the widely favored choice. However, it is possible to integrate Lean and Six Sigma and reap the full benefits that these methodologies can […]

Home mortgage loans in the United States usually closed in about four weeks even a couple of years ago. Some on-line mortgage loan originators are doing the same closings in about two weeks now. Safeco, one of the largest insurance services providers in the country, needed a week to make any changes in coverage in […]

One of the biggest challenges in any Six Sigma order fulfillment project is the scoping. Having clear boundaries on what aspects will and will not be covered in the project is paramount to its success. Scoping sometimes indicates that a single Black Belt project could overwhelm the Black Belt leader. With too large a playing […]

Lean and Six Sigma generally tend to be viewed as methodologies that are most successfully applied in a manufacturing environment. In the last several years, however, companies also have had notable results in transactional and administrative processes. Recently Medtronic, a global leader in medical technology, has successfully adapted Lean Six Sigma to apply even to […]

Although information technology (IT) organizations can share commonalities at a general level, each has its own, unique set of characteristics interacting in ways that result in their own performance signatures. Even performance measurements are not identical. Each is its own system, its own environment supporting a specific company’s needs. Just as companies are diverse in […]

Those in the information technology (IT) field often encounter service level agreements (SLAs) that define the performance a customer can expect from a particular process or service, such as a help desk. Often, these agreements are established by negotiation rather than by a more scientific approach that would be used in a Six Sigma process […]

While most information technology (IT) organizations are constantly struggling to demonstrate cost savings, too few are focusing on ways to add value to the business. Alignment with the business is where the emphasis should be for IT departments. CIOs today are actively involved in divesting business processes, and partnering with new offshore providers in countries […]

During a Six Sigma symposium, speaker after speaker presented good information on Six Sigma concepts, tools and approaches to use when working on a Six Sigma project. If these Six Sigma tools, approaches templates, etc., are good for Six Sigma projects, why not use them in day-to-day software development and IT processes? Learning Objectives It […]

A discussion about an ideal IT system often centers on user friendliness, system reliability, and implementation on time and on budget. These discussions should also include how to create more business value through the development of systems following a disciplined, fact based approach with a clear customer focus. For example, consider a telecom provider who […]

Information technology (IT) services are highly valued in today’s enterprise particularly those aligned with business needs. As IT departments transition from technology to service based management, more organizations are following the Information Technology Infrastructure Library (ITIL) framework. ITIL is a set of best practices intended to facilitate the delivery of high quality IT services. ITIL […]

“Let the process flow.” “Let the customer pull.” This is what is written in manufacturing books about making processes Lean. But it is not always that simple. Consider this banking example. A customer arrives at a bank branch: He enters, is welcomed by an employee and offered a cup of coffee. He explains his interest […]

“As technology moves more and more into the very fabric of our existence, the real-time existence of consumers and businesses and the economy, the reliability of systems will need to reach the level of dial-tone. Consequently, the techniques used to develop systems, the quality of these systems, and the demands on the performance of these […]

Since the early 1970s software and information technology (IT) has been significantly changing the way products, processes and services are designed, delivered and maintained. At an exponentially increasing rate, software and IT have become the driving force in the way people work, recreate and educate. Most experts estimate this global “industry” at about US $1 […]

Readers may be familiar with the results of a survey on the integration of Six Sigma and information technology (IT) published by iSixSigma Magazine in its May/June issue. The survey, conducted and analyzed by Michael Marx, research manager of iSixSigma, revealed four important truths which provide meaningful insight to any organization attempting to apply Six […]

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 […]

Since the start of the information technology age, software quality has been an ambiguous term, meaning different things to different people. It has been defined internally from the viewpoint of software developers; and it has been defined externally from the viewpoint of end users of the software. But either way, early in the history of […]

Most software and IT organizations have great difficulty measuring organizational efficiency and effectiveness, despite a bewildering array of metrics that have been proposed and occasionally used. However, a basic-yet-powerful set of metrics that gets to the heart of these issues does exist, and at the same time facilitates the application of Six Sigma. It is […]

Whether the business unit is called information systems, information technology, software development or some other name, the group that provides these services is often among the most misunderstood and undefined in a corporation. And it is no wonder, considering that technology capabilities and dependence are rapidly expanding, combined with an ever-changing array of desktop and […]

Lack of data may be the most frequently communicated barrier to identification and selection of projects in the IT domain. Fortunately, most organizations have a tremendous untapped resource that is easily accessible – their help desks or support centers. Help desks generally are good at solving problems or determining where more difficult problems should be addressed […]
