new and to control it is vital to the success of the new process (Gupta et al., 2007).
Rewarding and providing recognition to all involved is also important, giving everyone
a sense of pride in the hard work put into the project. Check sheets (Fig. 6.8) can be
used to show where different problems could arise, and can keep track of different
steps throughout the process or times that different products arrive. Check sheets are
a good way to monitor a process and can be used for various aspects of the tasks.

6.7 Summary

This chapter gave an overview of the Six Sigma approach to improving system per-
formance. Six Sigma provides an excellent toolbox of approach and methodologies to
analyze and improve project deployment or systems. Many of these concepts are
incorporated into the systems approach to minimize solid waste. Specifically, the use
of a data-driven, goal-focused approach that utilizes a variety statistical and process
analysis tools.
