Why Standard Six Sigma Analysis Toolkits Are Losing their Applicability

Apr 10, 2008
For better understanding, let us shed some light on some of the main reasons that are forcing businesses to look at the inherent limitations of standard Six Sigma analysis tools and techniques in terms of their applicability in today's highly competitive business environment.

Increasing Complexity of Business Processes

Over the years, business processes have become increasingly complex, making it quite difficult to carry out an analysis using the conventional Six Sigma statistical tools and techniques. Even if a business somehow manages to do so, it would not help much simply because there will be no certainly that the results obtained from the analysis reflect the true state of affairs.

There are simply too many variables to consider in most business processes that are being used nowadays and as such it's just not possible to statistically analyze a given system and make accurate predictions.

Processes Are In the Mode of Continuous Change

Earlier, businesses took a long time - sometimes even years - to make changes to their existing business processes, but now since the changes have become an everyday occurrence, especially in the high-tech industries such as IT and BPO, it just doesn't seem right to continue using the conventional analysis toolkits.

Analysis done through conventional toolkits takes a lot of time, which basically implies that by the time the analysis is over, the event in question would already have gone over to a new phase and as such would require going through a completely new assessment process.

Operable Life of Most Products and Services Is Continuously Decreasing

Since customers' needs and expectations are changing at a fast pace, the operable life of most products and services is on a downward trend. This in turn is forcing companies to continuously keep changing their product line and adding new features that might help attract new customers and retain existing ones.

Conventional Six Sigma analysis toolkits just cannot achieve this objective obviously because they are too slow at suggesting the best plan of action. They might be able to make way for accurate predictions, but since the thing that matters most is the timely assessment of changing customer needs and requirements, businesses just cannot afford to keep using them.

So, What Is The Solution?

Well, for that you just need to have a look at the current trends in the industry that is becoming increasingly dependent on the latest technological tools such as Six Sigma simulation. Enabled by advanced IT systems, simulation tools are functioning as the backbone of most of the Six Sigma quality improvement projects that are currently being implemented.

Since they provide adequately for most of the limitations of conventional Six Sigma analysis toolkits, they are increasingly being accepted as the perfect replacement by businesses worldwide. This certainly bodes well for the future of simulation, but obviously not so for the conventional Six Sigma analysis toolkits.
