5.1 Using the DMAIC Continuous Improvement Process In order to test the first part of the hypothesis, that while requiring additional upfront effort,
defining and measuring electricity waste for individual equipment will yield improvements in energy
savings, we conducted research in a manufacturing area that already had significant engagement and
success with the proof of concept study in the previous year. As Norelli noted, "After the initial
launch.. .more effort should be placed on quantifying the impacts of specific improvements. Not only
will this help employees prioritize their actions but through the process.. .additional insights may be
discovered" . We chose to utilize the well understood DMAIC continuous process improvement
framework common in six sigma literature. The approach, data, and results of this approach are
discussed in this section. 5.1.1 DMAIC applied to energy use reduction Limited examples, confined to short case studies, exist in the literature of specifically utilizing the
DMAIC process to reduce electricity usage, despite the fact that it is consistent with the PDCA
continuous improvement process endorsed by the EPA[5, 4].
Individual elements of the DMAIC approach ho...
