Six Sigma is a software development framework that was first introduced by the then employee of Motorola named Bill Smith. He framed the Six Sigma around the concepts of DMAIC, project scheduling, project management principles, rules, techniques, etc. Six Sigma is a well-preferred framework in many organizations owing to its exceptional advantages like profit maximization, easy project handling, easy evaluation of the project, quality maintenance of the end result or product, etc. Thus, there are certifications offered in Six Sigma, which help out the candidates to stand out among a group of individuals who applied for the same job. The types of certifications available in Six Sigma are: – Six Sigma green belt, Six Sigma yellow belt, Lean Six Sigma black belt Training, etc. Six Sigma was initially considered to be applicable and helpful for only manufacturing industries and firms, but lately, it has been discovered that, in fact, the techniques and principles of Six Sigma can be applied to varied types of organizations.
Whereas on the other hand, lean Six Sigma is a compilation of tools and techniques that are solely oriented towards waste reduction in the production chain. Processes or operations that are unnecessary and do not add features to the end product or result are detected efficiently and eliminated, thereby curbing extra expenditure and time on such unnecessary actions taken in the production line. Lean Six Sigma is actually the better-adapted version of Six Sigma that helps in decreasing loss, decreasing wastes, and thereby increasing the efficiency of the employees as well as of the production chain, increased time management skills of the production head, etc.
– Although the end result from both of the methodologies and principles is the same, the approaches to get the result of both the principle are different. While Six Sigma focuses on the variation causing waste, lean focuses on unnecessary actions producing waste.
– The approaches of Six Sigma are directed mainly at customer satisfaction with a better quality of the product, whereas the lean Six Sigma methodologies are focused mainly on reducing the loss and waste percentage of the production chain to ensure the higher profit margin of the production organization. Nevertheless, the quality is finally maintained in the lean Six Sigma approach too.
– While Six Sigma believes in distributing the responsibilities to different teams for efficient handling, lean Six Sigma holds the entire organization responsible for the deterioration of quality of the end product or result. Six Sigma stresses a team approach to development and betterment sequentially, whereas lean Six Sigma believes more in a holistic approach to development where every employee is equally responsible and dedicated towards the development of the whole organization.
– Six Sigma does not stress too much on certifications as a necessity for handling the production of a product by an organization; rather, it stresses the appropriate application of the Six Sigma principles to production for a better experience. But lean Six Sigma, as per its holistic approach, makes it quite compulsory for the individuals in the direct authorization of the product handling operations to get certified with the said certifications.
There are several differences between lean Six Sigma and Six Sigma, if not many. Both the approaches aim for a similar, if not identical, result. Yet, the differences make it a tad bit difficult for the recruiters, decision-makers of an organization based on manufacturing units to decide whether to undertake lean Six Sigma or Six Sigma for operation in order to achieve better profits with lesser yet valued efforts.

From the above-detailed review of the features and differences between the two approaches of lean Six Sigma and Six Sigma, it can be clearly seen that lean Six Sigma is the best of the two. Lean Six Sigma is a rapidly evolving latest version of Six Sigma that accommodates newer versions and new concepts of production and business management with that of the principles of Six Sigma, thereby ensuring a better profit for the concerned organization. Thus, an organization may undoubtedly opt for the lean Six Sigma approach for obtaining higher profits as Six Sigma slowly is getting merged with that of lean Six Sigma and is expected to null out soon.
