Unformatted text preview: specifically, a field study proved that applying process management approaches such as
the DMAIC improvement process can increase energy efficiency in a manufacturing area by approximately 10%. Increased energy efficiency resulted from a structured approach to cross-functional
collaboration, analyzing energy data to identify significant opportunities, and sustaining improvements though employee ownership and existing continuous improvement structures.
A separate field experiment with real-time feedback showed statistically significant improvements,
but only when senior operations managers in the area participated in the improvement process.
This important result, although likely influenced somewhat by the Hawthorne effect, supports prior
research that showed that low awareness and attention on the part of senior managers is a major
barrier to improving energy efficiency in manufacturing processes. Although real-time feedback is
probably not necessary to prompt the observed implementation behavior-changing programs such as
end of shift audits, it definitely increased visibility of the problem and additional improvements with
such a system in place is likely assuming engagement on behalf of area employees and managers.
