Hello iSixSigma readers! We are working on an article about gage R&R and need your help with data collection for analysis. What we need: Raw data itself (either 5-part or 10-part analyses including operators, parts, trials and measurements) The tolerance spread Is this one- or two-sided tolerance What we would like: Gage family information (e.g., […]

The webinar will be held from 11 a.m. to 12 noon Eastern and the cost is $49 (Register Now!)

Department of Defense logistics organizations are attempting to reorganize their efforts using a combination of business process improvement methodologies, such as Lean Six Sigma, which seeks to reduce process steps and errors often associated with them. They are also using modeling and analytics to review existing logistics process data.

Today the U.S. Patent and Trademark Office (USPTO) granted patent rights to MoreSteam.com for inventions developed by MoreSteam’s President, Bill Hathaway.

The job of any purchasing department is to source for reliable suppliers who deliver products conforming to specification on time and within a certain price range. The more data is available about potential suppliers, the better the decision will be. The question is, how should that data be analyzed? The following case study helps to […]

Driven by nationwide technologist shortages, an industry-wide focus on quality and rising consumer demand, healthcare is feeling the pressure to deliver more with less. Given this challenging environment, some organizations have come to the conclusion that taking the path of least resistance may not be the best approach. For many, delivering quality patient care is […]

Engineers, Six Sigma practitioners and other researchers often work with “hard” data – discrete data that can be counted and legitimately expressed as ratios. But what of “soft” data, things like opinions, attitudes and satisfaction? Can statistical process controls (SPC) be applied here? Can process variation in customer satisfaction, for example, be measured and then reported to […]

A repeated series of actions and variables is a process. A collection of processes is a system. Virtually perfect Six Sigma quality results from an optimal interaction of all the variables in a given system. Process and system questions we all face at work include: Which variables are the most important to the customer? Am […]

A Black Belt used Six Sigma to improve a transactional bank deposit process, resulting in yearly savings of $4 million.

Most organizations have a strong bias toward planning, managing and executing a multitude of supposedly value-added activities hoping that these (often isolated) activities will yield significant results. In rare cases, activities are spawned by careful strategic planning, tracked regularly by performance data, reviewed for adjustments and improvements and integrated across functions, divisions and geographies. However, […]

Most quality professionals recognize that Six Sigma is a breakthrough strategy. They understand that the methodology uses data to measure current process effectiveness and to validate improvement; uses proven statistical and quality tools to identify process gaps and improvement solutions; and uses change management processes for institutionalizing and integrating improvements in an organizations’ operational and […]

A large corporation recently conducted a competition to identify the organization’s best Six Sigma projects of the previous year. Out of more than a hundred submissions, only one actually validated its improvements with a comparative experiment (z, t, Chi-sq, etc.). What did the rest do? The same thing they did before Six Sigma. The mean […]

Many times in software development and information technology, attribute data is what is available. Thus, it is valuable to look closely at the nature of attribute data and explore some tips for making the most of it.

No data? No problem! The Lean Six Sigma process provides an excellent framework for all types of projects, even when there is little or no data.

Ordered category data is discrete data representing appraiser or client perception against a rating scale such as a survey or questionnaire. Black Belts learning to apply the Six Sigma methodology to ordered category data are traditionally taught analytical methods that include normal and Poisson distributions. This is probably due to Six Sigma’s beginnings in manufacturing. […]

A growing number of organizations are studying the commercial use of radio frequency identification (RFID). Several large companies have invested large sums in RFID development, and companies such as Wal-Mart plan to require RFID compliance from their suppliers. Nonetheless, many companies do not yet have a full grasp of what this technology may mean to […]

Six Sigma DMAIC and DFSS roadmaps provide the guidance needed for using facts and data to understand problems, opportunities and solutions to get results in a wide variety of project settings. For the routine cases, they give practitioners what they need. There are some situations, though, that can benefit from a broader view of Six […]

Companion Article This is one of two articles by David Wetzel that explore the value of developing a data management plan as the intial step in the Measure phase of the Six Sigma DMAIC methodology. The other article is “Data Management Plans Can Improve Collection/Validation.” Long project cycle times, frequently cited as an impediment to […]

In many industries, improvement projects quickly face an obstacle: The lack of easy to get and reliable data. This is especially true when the critical-to-quality elements (CTQs) of the project are “soft attributes” such as taste, smell or texture. Facing such a problem in the food and drink industries is obvious. While in a Kano […]

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 […]

  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 […]
