The term 'DMAIC' stands for the five main steps in the Six Sigma process improvement method namely Define, Measure, Analyze, Improve and Control.
DEFINE
* the customer and their 'Critical To Quality' issues and expectations
* the business processes that are involved, the boundaries of the project
* create a process map
* decide on the metrics 'Big Y', little y's and the x's
* form a project team and develop a project charter
MEASURE
* the existing process by gathering data from the process
ANALYZE
* the data
* identify the gaps between existing and desired performance
* identify sources of variation
* decide on the processes that will be improved
* gather more data ('measure') if necessary
IMPROVE
* propose solutions
* carry out pilot studies, design of experiments etc. to test and evaluate the proposed solutions
* develop an implementation plan
CONTROL
* implement systems and procedures to ensure the improvements are sustained
* develop procedures, control plans, staff training etc.
A Six Sigma project works through each of these steps in turn, completing each before moving on to the next.
