![]() ![]() Measure: Once the project has been outlined, deciding the metrics that will determine success can begin.Define: In this phase, team members focus on defining the parameters of their project, with scope, customer needs, budget and team development being sculpted from stated goals.Named after the five stages of the process, DMAIC offers a data-driven way for companies to evaluate the improvements they need to make to existing processes. If an organization wishes to resolve its process inefficiencies and maximize productivity, it needs a strategic approach to start. Six Sigma is an iterative process that’s characterized by two distinctive features: a data-driven quality strategy and an expertise hierarchy similar to martial arts. ![]() Failure Mode and Effects Analysis (FMEA).Some of the tools and techniques include: Lean uses primarily qualitative methods to identify areas of waste along a product or process lifecycle and continuously looks for ways to improve operations.Īlthough the successful implementation of either methodology can result in superior business processes and products, a key distinction between Six Sigma and Lean is that Six Sigma focuses on variance - i.e., the number of products that don’t adhere to a predetermined standard - while Lean focuses on eliminating waste and adding value.įirst popularized by Motorola in the 1980s, Six Sigma applies several management tools to enhance business processes.This corresponds to six standard deviations from the mean - symbolized by the Greek letter sigma, or σ - and is where the method gets its name. Six Sigma uses statistical analysis and other quantitative methods to minimize variance and flawed products to a level of 3.4 defects per million opportunities.The metrics may vary by company, but typically, this can include increasing production, reducing delivery time or time to market, eliminating defects and errors, limiting variance, and helping businesses meet or exceed their bottom line.ĭespite their common goals, the approaches Six Sigma and Lean practitioners take to reach these goals can vary significantly - though there may be some overlap between the two. The focus of Six Sigma and Lean are to improve production to optimum levels of quality. This article will define Lean and Six Sigma, describe the key components of each methodology and explain the primary differences between the two methods. The optimization method chosen will largely depend on the industry, the organization and the application needs, but if the goal is to improve the efficiency of business processes, two of the most common process improvement strategies include Six Sigma methodology and Lean methodology. That means eliminating defects, minimizing variance, maximizing throughput, and cutting out all wasted steps along the way. ![]() From high-tech enterprises in Silicon Valley to automotive manufacturers overseas, organizations of all types must learn to optimize their processes at every level of production. ![]()
