DMAIC (Define, Measure, Analyze, Improve as well as Control) is an information-driven excellence technique for process enhancement. The characters in the phrase stand for the five stages of the procedure. It is an essential component of a six sigma program; however, it may also be used as a stand-alone quality enhancement technique or as a component of many other procedure enhancement projects including lean.

The methodology's main concentration is on recognizing as well as accomplishing what the customer needs, as this is regarded as critical to the profitability of a manufacturing procedure.

• Determine one's clients' needs as well as requirements.
• Determine a project that is a good fit for six sigma initiatives focused on company goals, consumer requirements, as well as comments.

• Decide how to evaluate the system's performance.
• Determine the main inner procedures that drive CTQs as well as assess the present level of fault generation concerning those activities.

• Identify the most probable faults' causes.
• Recognize why failures occur by highlighting the major factors that are most prone to causing variation in the process.

• Identifying ways of removing the sources of faults.
• Verify the important factors as well as quantify their influence on the CTQs.
• Determine the maximum acceptable ranges of the relevant factors as well as a mechanism for assessing the variables' deviance.
• Alter the procedure such that it remains within an appropriate range.

• Decide how to sustain the gains.
• Put mechanisms in place to guarantee that the important factors remain under the redesigned system's highest acceptability ranges.
