By embracing one or the other, or even combining the two together, it is possible for enterprises to refine processes and produce better results. This can help to reduce costs and produce better quality products.

What is ITIL

ITIL, as the name suggests, is used by the IT industry. Set up in the UK by the Office of Government Commerce, it uses a framework that can help define and improve IT related services.

The ITIL framework is comprised of several components that can either be used together or individually in order to improve business practices and operations. With a focus on service support, ITIL frameworks often include the management of the following IT issues:

  • Incidents + problems
  • System change & configuration
  • Network availability + capacity
  • Service level + continuity

To improve efficiency and user experience, as well as refine and streamline IT processes, each of these components is managed by a set of ITIL best-practice procedures, similar to how Six Sigma dogma refines and streamlines business practices.

The Difference between Six Sigma and ITIL

Whilst using both models can benefit businesses, Six Sigma and ITIL aren’t generally used together, but rather in combination as a complimentary set of practices that can improve businesses from a number of angles.

Six Sigma is a methodology based on formulas, calculations and the analysis of business processes in order to improve them. Whilst Six Sigma focuses on the ‘how’ of improving processes, ITIL is more concerned with the theory and guidelines put in place to determine the ‘what’ of the processes.

By utilising ITIL methods, a business can determine what needs to be done in order to improve processes and areas. Six Sigma on the other hand, can help a business work out what the cause of an issue is or where a fault in a process lies and then ascertain how this can be fixed. However, as Six Sigma relies on statistical analysis, it is best practice to sample process improvements on a small trial basis to ascertain whether the benefits are scalable.

Combining Six Sigma with ITL

Whilst the two do not work in complete unison, there are some effective ways to combine Six Sigma with ITIL practices. For example, a company looking to move its systems over to an ITIL framework will be able to use the principals of Six Sigma to ensure that the ITIL process is appropriate for the objectives and aims of the company.

Whilst ITIL is more concerned with the IT areas of a business, Six Sigma can be applied to a range of different industry types and work areas in order to improve overall processes for a company.

Six Sigma Training

Both Six Sigma and ITIL require effective staff training in order to gain the best results for a company, which is why a dedicated training company with the right knowledge and expertise will be a valuable investment for your company.

Training can be arranged in-house, externally or online, making it possible to train your entire staff base or just individuals if necessary.

Next Steps

Using Six Sigma and ITIL can benefit your business by streamlining the way you work and increasing savings, profits and productivity. It will also help improve your staff’s development, which will have a positive effect on your customers and how they perceive your business.
