Monitoring process improvements is a crucial part of Lean Six Sigma, a methodology that aims to eliminate waste, reduce variation, and enhance customer satisfaction. By tracking the performance and outcomes of your improvement projects, you can ensure that they are aligned with your goals, identify any gaps or issues, and sustain the benefits over time. In this article, we will discuss how to monitor process improvements using some of the tools and techniques of Lean Six Sigma.
Define Metrics and Baselines
Before you start implementing any process improvements, you need to define what metrics you will use to measure the success of your projects. These metrics should be relevant, reliable, and realistic, and reflect the voice of the customer and the voice of the process. You also need to establish baselines for your current state, which are the values of your metrics before any changes are made. Baselines will help you compare your before and after results, and quantify the impact of your improvements.
Collect and Analyze Data
Once you have defined your metrics and baselines, you need to collect and analyze data on a regular basis to monitor the progress and performance of your process improvements. You can use various tools and techniques to collect and analyze data, such as surveys, interviews, observations, checklists, charts, graphs, histograms, control charts, Pareto charts, and root cause analysis. Data analysis will help you identify trends, patterns, anomalies, and opportunities for further improvement.
Use Feedback Loops
Feedback loops are mechanisms that allow you to receive and respond to information from your customers, stakeholders, and team members about your process improvements. Feedback loops can help you validate your assumptions, test your solutions, evaluate your results, and adjust your actions accordingly. You can use different methods to create feedback loops, such as focus groups, customer reviews, surveys, audits, coaching, and mentoring.
Implement Control Plans
Control plans are documents that describe how to maintain and monitor the improved process and prevent it from reverting to the old state. Control plans specify the roles and responsibilities of the process owners and operators, the control methods and tools to be used, the frequency and criteria of monitoring and evaluation, and the corrective and preventive actions to be taken in case of deviations. Control plans help you standardize and document your process improvements, ensuring their sustainability and consistency.
Review and Report Results
The final step in monitoring process improvements is to review and report the results of your projects to your stakeholders and sponsors. You should review and report the results periodically, using the metrics and baselines that you defined at the beginning. Highlight the benefits and challenges of your process improvements and provide recommendations for future actions. Reviewing and reporting results will help you communicate your achievements, celebrate your successes, and learn from your failures.
