The methodology, in whole or in parts, depending on the audit scope, is based on the qualitative structured method – DMAIC (Define, Measure, Analyze, Improve and Control).
Define. The first step is to define the customer and issues of importance to them, along with the process and project parameters.
Measure. Once the process is defined, data about defects and other measures is collected and then compared to the original parameters to identify underperformance.
Analyze. Analysis of the data is made to identify gaps between the goal and actual performance, explanation of why the gaps occurred, and ranks possible improvements.
Improve. Based on the analysis, solutions are created and implemented.
Control. During the control phase, systems are revised to incorporate the improvements, and employees are trained in the new processes. The goal of this phase is to prevent backsliding into the previous process by ongoing monitoring.
