Six Sigma (6σ) is a methodology that is applied to reduce defects in a given process. In other words, the principles and associated tools of Six Sigma can be applied to improve quality, increase efficiency, reduce losses and drive performance excellence in a business. A Project Team is formed within a business to drive the Six Sigma Journey. Green Belts are the project leaders in Six Sigma, acting as the driving force from project kick-off to project closure. Ideally, there is also a Black Belt or Master Black Belt assigned to the project. Their role is to help guide the Green Belt and ensure the integrity of the data analysis, hypothesis testing and conclusions being drawn are sound throughout the project duration.
6σ is deployed using a firmly established process known as DMAIC.
Define Phase - baselines the process that needs improvement, builds the business case, defines the project objectives and team structure and most importantly, obtains the green light for project kick-off.
Measure Phase - defines a plan for gathering data, conducts quality checking of the data collected and develops a clear measurement system and key performance indicators for the project.
Analyse Phase - consists of process mapping, identifying value and designing of experiments. This phase is a bridge between theory and hard data analysis (hypothesis testing and regression analysis) in preparation for identifying improvements.
Improve Phase - develops a control plan for the process in question, designs tracking and execution of required action plans and communicates the benefits of the project.
Control Phase - ensures that actions are completed, KPIs are continuously tracked, process improvements are quantified, future improvements are proposed and captured, process changes are embedded through standardized work, project deliverables are communicated to the wider business and the project itself is formally closed.
So how could your team benefit from Six Sigma?
Businesses that actively deploy 6σ Projects enjoy high customer satisfaction, deliver best in class levels of operational efficiency and demonstrate significantly elevated margins and profitability. Furthermore, you will be amazed at the success your business enjoys by training, developing and trusting in your people. By implementing Six Sigma you will be taking serious steps towards a sustainable performance focused culture for success.
