High quality services are a requirement for every service industry, including information technology. Two methods are widely used to ensure high quality service management: Six Sigma and IT Infrastructure Library (ITIL). Each method has its advantages. However, most companies prefer to use both.
IT professionals should consider obtaining the ITIL certification. This certification will give insight into how to use ITIL to combine Six Sigma’s benefits. They all have their own differences, but they share one thing in common: their focus on customer satisfaction. Let’s take a look at them in detail.
What is Six Sigma and ITIL?
ITIL is a framework that supports and delivers IT-based services. There are many components to the ITIL model. Support includes configuration management, problem management and release management. Service delivery includes service management, financial management, service management, service level management, and capacity management. Each component has its own recommended procedures and practices, which can be used individually or in combination.
Six Sigma is widely used for operational process improvement, even outside of IT management. This formal approach identifies the most important processes in your business and uses Six Sigma to improve them. It also measures the quality of the output. It is compatible with IT service management and emphasizes economic savings. Six Sigma is known for its focus on customer satisfaction and prioritization.
Six Sigma and ITIL: Differences
Six Sigma and ITIL are not combined in a typical scenario. They can be used together as a complement to each other to improve businesses to a large degree.
Six Sigma is primarily based on formulas, calculations, and the analysis of business processes in order to improve them. It focuses on improving processes. ITIL focuses more on the theory and guidelines that are required to determine the ‘what.’
ITIL methods can help businesses identify what needs to be done to improve their processes. Six Sigma, on the other hand, helps businesses identify the root cause of an issue or where the process went sour. It then identifies the problem and suggests solutions. It then creates a method to measure the services in a tangible way. Six Sigma uses statistical analysis. It is best to test process improvements on a trial basis in order to determine if they are scalable.

Combining the Approaches
Even though they have some differences, both approaches offer many advantages when combined. ITIL outlines what an organization should do, but not how. IT professionals within an organization must determine the process flow and create detailed work instructions. In addition, Sig Sigma tells how
