Six Sigma can help by defining the problem (lack of effective deferred maintenance processes), measure the internal processes that affect factors critical to quality. Analyze the measures: where are the defects? Why are the errors occurring? What is the cause of the poor performance? Improvements: using the analysis, generate ideas to improve factors critical to quality (looking at scheduling calendars, creating timeline of maintenance needs), Control: variances appearing in the project are corrected...are they within the new improvement specifications
