To improve the quality of any process and consequently the product, Six Sigma has become the go-to tool for such requirements. Earlier it was TQM or Total Quality Management that was the dominant force of quality control. It was based on 14 principles of Edward Deming who is credited with its genesis. TQM focused mainly on making an environment where employees would continuously improve their processes to provide on-demand products and services that customers will find good value.

However, these days, that spot has been attained largely by Six Sigma. It is because the methodology of Six Sigma has a unique and high standard for its quality. As a general rule, a defect level of 3.4 out of a million pieces is acceptable within a shipment. That is an immaculate level of 99.99966% defect-free products that make Six Sigma a favorite of so many people.

Six Sigma’s birth is comparatively young than its predecessor (TQM). Six Sigma existed even in the 1920s and but the name was officially coined by Bill Smith who served as the chief engineer in Motorola during the 1980s. Later, the chairman of the same company made this process the objective tool, and it has helped the company save up to $16 billion up to now.

Features of Six Sigma

  • Six Sigma has two methodologies; DMAIC and DMADV. DMAIC which stands for Define, Measure, Analyze, Improve and Control, is used for existing systems. DMADV stands for Define, Measure, Analyze, Design, Verify and is used for the starting of new processes.
  • It tries to achieve leadership support and commitments.
  • Six Sigma is implemented based on sound and accurate data. The data given for the implementation tries to reduce the dependency on human experiences and thereby, lower the chances of errors.
  • Another main feature of Six Sigma is its focus on changing the ways employees function and train them in ways that would help them become more effective and efficient in achieving their goal.

Six Sigma for Marketing


Marketing is a crucial aspect of any business. It is because, in order to convince others to buy your product consumes a lot of time and resources, along with a hefty list of skills. It has been a very popular myth that Six sigma is only meant for operations. The reason for that might be because operations professionals are emphasized a lot on Six Sigma compared to any other department within a company.

However, Six Sigma can be used for any deportment, as long as they include standard processes. Marketing also involves a series of systems, which ultimately makes it a process. In fact, it is already used in major corporations such as Bank of America, HSBC, Dell, GE, Xerox and many more.

Six Sigma can be beneficial for marketing professionals by creating excellent presentations and proposals. Companies like GE and Motorola have started using it and that is why they have gained a high reputation using this approach. Companies can also maximize their profits by integrating marketing with Six Sigma.

The define phase in terms of marketing can be identifying the customer expectation which can ideal for the industry.

The measure phase can involve things like taking notes of the problems associated with the process. It can be the lack of ads on the relevant platforms, unimpressive graphics in the ad, futile content or any such issue. This phase is dependent on data gathering.

The analyze phase will involve measuring the gap between the current standard of quality to the ideals of the required ones.

The improve phase will take steps to take steps in meeting the gaps. This could be any number of steps you need to take in order to improve the ad quality.

The control phase involves steps the marketing team has to take in order to keep those standards up for the remainder period.

So, as you can see from this example, Six Sigma can be used for any department with the aim of improving the quality of the process.

Six Sigma for Finance
