The IT practitioners' must see their world from two different perspectives how the business uses their services, and how IT provides services to the business. Both views distill to one concept the value stream, applied in two different ways.
In the near term, most software organizations can realize meaningful cycle time reductions by adopting Agile methods. In the longer term, it remains important to address and measure all of the factors that contribute to longer cycle times.
One way to extend the Lean Six Sigma toolkit is by introducing new, nonlinear approaches to improvement within the transactional improvement space particularly upstream in the areas of innovation, new product development and the software development life cycle.
Most organizations have a strong bias toward planning, managing and executing a multitude of supposedly value-added activities hoping that these activities will yield significant results. Most do not. But there is another better way.
For a software company to make a case for process improvement, reliable measurement data is needed. Unfortunately that data normally comes from an improvement project.
When facing an imminent layoff, what path should Six Sigma professionals with a technical background take to get into the information technology (IT) arena?
Cause-and-effect diagrams help identify factors (x's) that may drive changes in a results variable of interest (Y). But when they are not enough, causal loop diagrams can convey causal interconnections that better reflect the way things are.
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? The answer seems to be Six Sigma first...at least a little bit first.
CMMI/PSP/TSP are among the several potential choices of software development process definition that can lead to improved software project performance. The full potential of the data produced by these processes cannot be fully leveraged without applying the more comprehensive Six Sigma for Software toolkit.
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 iSixSigmas Best Places to Work list. Computacenter was ranked at No. 10 for this years list, the same position it was given in the 2010 list.

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.
Information technology businesses can create better service level agreements (SLAs) by using a more scientific approach than just negotiating with their customers. Yet the method is not complex and it does not require a Six Sigma deployment.
Often considered an island unto itself, technology development and implementation does not really occur in a vacuum. However, the interrelated nature of managerial, quality and technological systems, and the inherent benefits of a truly integrated view are not necessarily evident…
Defect prevention in software development involves a structured problem-solving methodology to identify, analyze and prevent the occurrence of defects. This article outlines the five general activities of a defect prevention methodology.
Agile changes the nature of planning and tracking. In agile, the available development capacity in resources and schedule is assessed and considered fixed at the outset. That assessment guides the scope of features promised for a delivery cycle.

Practitioners must carefully consider the potential gains from using Lean Six Sigma in an Agile software development environment. But first they need to understand what sets software design apart from other product development.
This article describes a successful Green Belt project in information technology in which a software development team applied Six Sigma to reduce the resolution time of software defects and minimize rework, thereby increasing customer satisfaction.
The demand for business intelligence is increasing at a rapid pace across all industries in todays tough economic climate. As senior executives look to optimize existing business processes that can lead to bottom-line and top-line benefits, one option is to tap 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.

It has been obvious from early on that software development could not be done in an ad hoc manner. It needed a methodology like Six Sigma to deliver attributes like robustness, correctness, adaptability, reusability and maintainability.
A specific process solution, orchestrated for one IT organization, is unlikely to fit perfectly in another IT system. This means that importing a set of processes into an organization, without some kind of review for "fit" carries momentous risk.
Six Sigma practitioners in the IT industry need to look inward to keep application of the method simple and relevant. Practitioners should consider a three-phased deployment model alongside a project selection method matching the effort's maturity.
Implementation of a project-specific process map during software development can help practitioners improve their performance and meet project objectives.
The goal of code inspection is to identify software faults early in the software development lifecycle, but it is not always known if those inspections are effective. A prediction model can be applied to evaluate this process and refine the achieved quality level.
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…

When comparing implementations across companies, using the common language of DPMO and Sigma levels will assist in understanding benchmarking data.
Effort accounting is essential in software/IT Six Sigma projects because labor usually is the most controllable cost. To know if a process improvement has the desired impact, a company must know how time was spent, before and after the improvement.
This article will present various tools and techniques for use in creating a Defect Prevention (DP) strategy that, when introduced at all stages of a Software life cycle, can reduce the time and resources necessary to develop high quality systems. Specifically, how implementing a model-based strategy to reduce Requirement Defects, Development Rework and Manual test development efforts will lead to significant achievements in cost reduction and total productivity.
Learning to reduce project duration can be critical, but it could be more important to reduce the predicted-to-actual project duration gap (the variation). That gap is a particularly familiar enemy in the software world, causing problems with project cost, disappointed customers, conflicts with management, development team morale, and more. This article identifies three ways to do so.
A multibillion-dollar software manufacturer used Six Sigma, and a 5 day project saved more than $12 million.
Successful software testing requires five essential elements - test strategy, testing plan, test cases, test data and a test environment. If any element is missing or inadequate, the test effort will most likely fall far short of its objectives.
Software development environments have unique cultural dynamics and lower process maturity states that must be taken into account for successful implementation of Lean Six Sigma projects
Five essential elements are required for successful software testing: test strategy, testing plan, test cases, test data and a test environment. If any one of these five elements is missing or inadequate, your test effort will most likely fall far short of what you could otherwise achieve.
