Six sigma is a set of management tools and strategies that streamline business processes by reducing the defects causing inefficiencies. For instance, it may be used to enhance the customer experience by shortening the time that they spend queuing. Lean Six Sigma achieves this by eliminating the bottlenecks that cause queues to move slowly. It enhances the effectiveness of the business process by defining, evaluating, studying, improving and monitoring (DMAIC). Whenever an organization implements the Six Sigma strategy, there is always an objective.
