It takes more than quick fixes, outsourcing and downsizing to consistently achieve growth and profit objectives. For companies to grow, they need to master eight basics of Lean Six Sigma.

Among the tried and true tools in the Six Sigma kit, cause-and-effect diagrams in the simple form of a tree, a fishbone or a Y-to-x diagram are a big help in identifying factors (x’s) that may drive changes in a results variable of interest (Y). There are times, though, that a flat, two-dimensional hierarchy does […]

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 […]

Five essential elements are required for successful software testing. If any one of the five is missing or inadequate, the test effort will most likely fall far short of what could otherwise be achieved. Exploring these five essentials can help improve the effectiveness and efficiency of any software testing program. Here are the five essential […]

A variety of analyses can be done during the Analyze phase of a Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) software project with data from Fagan-style inspections. These analyses suggest possible implications when considering Improve activities. Analyses used here are based on a real situation and the conclusions drawn are valid in that situation, […]

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 […]

Agile changes the nature of planning and tracking. The term agile is used to refer to a variety of software development frameworks (like scrum, XP, crystal methods) which all share approaches to scoping work and managing the delivery of working features. Using scrum as an example (Figure 1), it is clear that the available development […]

Many times, a company is required to do a root cause analysis once a defect or bug is found in the software system it has developed and released to customers. Such an approach is not only costly, but almost without exception results in customer dissatisfaction. What is needed is a proactive approach to understand the […]

Software project managers, who are responsible for shepherding software projects to completion, often feel like they are on a cross-country trip with several youngsters in the back seat. It seems like every few minutes someone asks, “Are we there yet?” Cycle time for a software project is usually understood to mean the elapsed calendar time […]

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 […]

  The total customer relationship management (CRM) market will reach $12.1 billion by 2004, representing an annual growth rate of 29.9 percent, according to the 2000 CRM Market Forecast and Analysis prepared by IDC, the world’s leading provider of information technology data and analysis. It is highly unlikely, however, that the CRM market will reach […]

A survey sponsored by the Carnegie Mellon Software Engineering Institute (SEI) finds that Six Sigma is feasible as an enabler of the adoption of software, systems and IT improvement models and practices.

Software can be a helpful tool but it is not a magic wand. After investing half a million dollars in tracking software for its call center and still seeing a high volume of complaints, one company used DMAIC to turn a disaster into a success.

Digital check processing. Fraud detection. Compliance monitoring. Trading floor analytics. These are all integral functions for many modern financial service institutions. And all have one thing in common – they require a huge amount of computing power. One approach to providing fast responses even with highly complex computations is distributed computing, or creating a shared compute […]

Many software organizations are beginning to use Six Sigma, and are finding that they need to rationalize its relationship to the standard software development life cycle process. A number of issues and alternatives arise when this need is addressed. Roadmaps and Software Development Life Cycles (SDLC) Six Sigma includes two complementary roadmaps. The first of […]

“Use cases,” a term coined by Ivar Jacobson early in the evolution of object-oriented thinking, have been widely accepted as a helpful way to understand and document the functionality that is important in all kinds of software or business systems. Anyone within miles of object-oriented design will be familiar with the typical application of use […]

Quality function deployment (QFD) is a tool that appeals to many engineers and designers. It looks so nifty that they think, “There just has to be a place to use this.” Experience shows, though, that with its niftiness comes a certain risk connected with trying to apply QFD in places or in ways that it […]
