The four stages prior to this one will determine how successful we are in the Control phase. Hopefully, we utilized the correct change management strategies, such as identifying the key stakeholders; if we did then a successful control should be within our grasp. The purpose of the Control phase is to establish tools that will ensure the key variables stay within the accepted variances over the long run. At this point, the group will create a formula for handing off the process which would include response procedures and educational information to guarantee the performance and long-term project savings.
The group would complete the phase by establishing the next phases for supplementary Six Sigma process improvement prospects.
