Six Sigma Methodology

 

Six Sigma Methodology

Six Sigma is an innovative and adaptive set of methodologies geared toward improving the efficiency and effectiveness of corporate processes. Originally introduced by the Motorola Corporation in 1986, it has evolved to become present within the most successful business improvement strategies and is attributed with reducing the number of defects in manufactured goods to less than 3.4 per 1 million units. Six Sigma uses two different sets of methodologies, DMAIC and DMADV, as lenses to examine and address complementary aspects of business processes. The DMAIC and the DMADV distinctions are aimed at viewing different sectors of a business simultaneously but addressing them separately. Despite unique distinctions, the methodologies overlap during the examination process and share the same end goal – improvement of business processes.

Each methodology has its own set of guidelines and goals targeted at improving business processes through the use of data collection and statistical tools. While the methodologies are designed to achieve the same thing, there are noteworthy differences between the two that should be considered by professionals in leadership roles or in business environments with a wide range of organizational settings.
