What are the best ways to monitor solutions during the Control phase of the DMAIC model?

The DMAIC model is a structured approach to problem solving that stands for Define, Measure, Analyze, Improve, and Control. It is often used in Six Sigma projects to improve quality and efficiency in processes. In this article, you will learn what are the best ways to monitor solutions during the Control phase of the DMAIC model, which is the final and most crucial step to ensure that the improvements are sustained and the problem does not recur.

1 Control objectives

The main objectives of the Control phase are to verify that the solutions implemented in the Improve phase are effective, to document the results and the lessons learned, and to establish a system of control measures and standards to prevent the problem from happening again. To achieve these objectives, you need to monitor the key performance indicators (KPIs) of the process, compare them with the baseline and the target values, and evaluate the impact of the solutions on the customer satisfaction and the business goals.

Na fase de Controle do DMAIC, os objetivos centrais são garantir a estabilidade e sustentabilidade da solução implementada. Isso envolve manter o processo consistente, assegurar conformidade com padrões, e atender continuamente às expectativas do cliente. A eficácia é promovida por meio do monitoramento de indicadores-chave, prevenção de recorrências e facilitação da comunicação entre as partes envolvidas. Esses objetivos convergem para estabelecer um ambiente controlado que favorece a durabilidade da solução e a melhoria contínua ao longo do tempo.

2 Control tools

The Control phase of the DMAIC model can be monitored with several tools, such as control charts which show how a process variable behaves over time and indicate whether it is within the acceptable limits or not. Standard operating procedures (SOPs) are documents that describe the steps and best practices to perform a process or a task, while audit checklists are lists of questions or criteria used to assess compliance and performance. Additionally, dashboards are visual displays that summarize key information and the status of a process or project, helping to communicate results and monitor trends and performance indicators.

This where you have to be careful. Visual displays have to be simple. I call it the walk by test. When you walk by the graphs/charts must be simple to read so when you walk by the charts will show, Good or Bad. Bold lines, going up is GOOD. down is BAD. Headline of the graph the same. Bold and simple.

3 Control challenges

When monitoring solutions during the Control phase of the DMAIC model, you may face common challenges such as resistance to change, lack of ownership, and complacency. To overcome resistance to change, involve and engage stakeholders, explain the rationale and value of the solutions, and provide support and recognition for the change agents. To address lack of ownership, assign and communicate ownership and accountability for the solutions, provide training and coaching for skills and behaviors required, and create a culture of continuous improvement and feedback. To combat complacency, set and review goals and standards for solutions, measure and celebrate results and achievements, and identify and address root causes of any problems or issues.

4 Control tips

To monitor solutions effectively during the Control phase of the DMAIC model, it is important to choose metrics that are SMART for the process and solutions, and align them with customer needs and business objectives. Data should be collected from reliable sources, and analyzed with appropriate statistical methods and tools. Control measures and standards should be implemented and reviewed periodically to ensure effectiveness. Additionally, results and lessons learned from the solutions should be documented and communicated to relevant stakeholders using clear language, visual aids, and by soliciting feedback.
