Using Censored Data in Transactional Processes

Censored data is commonly used in reliability studies to determine the mean time to failure in order to establish warranty and maintenance periods for products. A large number of samples are subjected to either normal-use or accelerated-use conditions. Failure modes and occurrences are logged. Plotting the distribution of the sample failures over time allows the…

Six Lessons for Deploying a BPM Workflow Product in a Transactional Environment

Complex, multi-team processes in transactional operations can often be almost invisible in operation and execution – until, that is, something goes wrong. Transactional process failures are common: failed online transactions, payments not made on time, double bookings and lost orders are frequently encountered errors. These processes often involve manual tasks and multiple unconnected systems, are…

What Manufacturers Can Learn from Transactional Companies

In the evolution of continuous improvement, the Six Sigma methodology began in the manufacturing sector and later spread to other transactional businesses. While many transactional companies, such as advertising agencies and other service-oriented organizations, still look to manufacturers to learn about the application of Lean Six Sigma, there are lessons that manufacturers can learn, as…

Measurement Systems Analysis in Process Industries

The gage R&R study is the standard tool in the Six Sigma process improvement methodology to evaluate the adequacy of a measurement system with regard to measurement variability. While it is well established and widely used in the discrete manufacturing industry, it is less useful in process industries where the nature of measurements is different,…

Trusting the Data: Gage R&R in Transactional Projects

An essential component of any Six Sigma project is the gage R&R step conducted during the Measure phase. Traditional training will cover the full analysis of variance (ANOVA) of a set of continuous data, an attribute gage R&R for discrete data and the destructive gage R&R. Since it is sometimes difficult to apply these tools…

Mining for Lost Gold in the Transactional Environment

Searching for lost gold in the transactional environments that are major components of all organizations is a Six Sigma imperative. A number of ways are available for successfully mining transactional processes, thereby reaping significant savings. Transactional- or service-focused Black Belts and Green Belts address problems which center on the elimination of process chaos. Transactional chaos…

DOE for Services: Right Training Makes It a Valuable Tool

When it comes to mastering design of experiments (DOE), many quality professionals experience a steep learning curve. DOE can be complex, and to fully understand and apply it, professionals need to learn when to use it, how to set up the experimental design and how to interpret their results.  Service quality professionals face an even…

Overcoming the Challenges to Project Realization

Black Belt project would end with a concise set of action items being turned over to the transition owner who would then swiftly implement them and achieve the desired results. But for many Six Sigma practitioners in transactional environments, simply handing off the project does not guarantee that the gains will be realized. Even in…

‘People Complexity’ Can Require a Special Roadmap

Despite the growing awareness that the standard Six Sigma DMAIC toolkit can be applied to process problems in so-called transactional environments – as well as manufacturing – improvements to existing processes do not always involve just tweaking of “settings” in the process. This is because processes in transactional environments contain lots of what have come…

Minimizing Risks: How to Apply FMEA in Services

It will probably come as little surprise that something called failure modes and effects analysis (FMEA) evolved at the National Aeronautics and Space Administration, an environment where the interest in preventing failures is extremely high. FMEA was later popularized by the automobile industry and in recent years has become more widespread among Six Sigma practitioners….

Turning Judgment Calls into Reliable Data with Gage R&R

One of the biggest challenges in making improvements in transactional processes is getting data which can be relied upon. There is an abundance of categorical data in transactional areas – situations where a judgment call is required: Is something right or wrong? Is the application complete? What type of error was made on the request…

Examples of Strategies for Healthcare and Other Services

Six Sigma has been used extensively in improving manufacturing organizations, but only relatively recently has it been used to improve processes outside the manufacturing arena. In our book Six Sigma Beyond the Factory Floor, my co-author, Dr. Ronald D. Snee, and I examine process improvement in the rest of the economy, such as financial services,…

Calculating Process Efficiency in Transactional Projects

The principles of Lean manufacturing are applicable to any business process. This article reviews some of the common problems seen in transactional projects and outlines an example where simple graphical methods are used to interpret cycle time data. Identifying and characterizing the non-Lean processes facilitates the application of 5S, brainstorming and other improvement tools with…
