CONTROL
The 5th phase of a DMAIC Project:
Control Phase: The last phase of DMAIC Project, where we ensure that the processes continue to work well, produce the desired production, and keep up quality standards. The final capability is determined, and the closing performance and all related changes are documented on the closing contract. This phase is not as statistically intensive as the MEASURE, ANALYZE, and IMPROVE phases.
The ultimate goal of Control is the overall assurance that a high standard of quality is met with the customer’s expectation. Customer's satisfaction depend on this, so control is fundamentally associated with quality.
Since the main aim of Six Sigma is to improve the overall process by reducing defects, quality control chart for detecting variation, an important method for keeping the whole process on track; for enabling us to spot trouble and fix it; and for judging how effectively the project was executed and implemented.
Quality is at the core of Six Sigma philosophy. Eliminating defects have everything to do with achieving perfection. Whether we touch perfection or not, the effort defines our attitude toward quality itself.
There can not be enough importance placed on the significance of giving the same high level of energy and commitment throughout this phase. Satisfaction and anxiety can set in for the sake of bringing closure and receiving some form of closure or acknowledgment.
Key Features:
- Implement control design
- Verify long term capability
- Continuously Improve Process
Objectives:
To understand the importance of planning and execution against the strategy and determine the approach to be taken to assure the success of the targeted outcomes.
How do we guarantee Performance?
- Validate reduction in cause Sigma improvement resulted from solution.
- Identify whether additional solutions are necessary to achieve goals.
- Identify and develop replication and standardization opportunity.
Conclusion:
The project team determines how to technically control the newly improved process and creates a response plan to ensure the new process, and also maintains the improved sigma performance.
