Lean Six Sigma / DMAIC

Introduction

For newcomers to Lean Six Sigma/DMAIC

Lean Six Sigma is a synergistic business strategy that combines Lean manufacturing/Lean enterprise and Six Sigma to eliminate waste (non-value-added processes and activities) and reduce variability (to improve quality and predictability). It focuses on improving process speed, quality, and cost by addressing inefficiencies and defects, aiming for near perfection in all company processes.

Lean Principles focus on value stream mapping to identify and eliminate waste, ensuring that every step of a process adds value from the customer’s perspective.

Six Sigma uses a data-driven approach, utilizing the DMAIC (Define, Measure, Analyze, Improve, Control) framework to systematically improve processes by eliminating defects and reducing variation.

Lean Six Sigma offers a comprehensive approach that focuses not only on quality improvements (via Six Sigma) but also on speed and efficiency (via Lean), making it a powerful tool for organizational improvement and customer satisfaction.

How to apply it?

This guideline outlines a comprehensive approach to enhance process improvement initiatives by integrating Six Sigma with process mining, process design, and simulation. Each stage of the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) framework is supported by specific capabilities from these methodologies, ensuring a robust, data-driven, and iterative process improvement journey.

1. Define Phase

• Objective: Identify the scope, objectives, and key metrics of the process improvement project.
• Process Mining: Utilize exploratory process mining tools to gain an initial understanding of the current process. Analyze historical data to uncover performance metrics, variances, and potential issues within the workflow.
• Process Design: Begin conceptualizing redesigns or modifications that might address identified inefficiencies or issues. Use BPMN diagrams to map out potential changes and improvements.
• Capability: Visualize current processes to set clear improvement objectives. This includes creating detailed process maps and diagrams to provide a comprehensive view of the workflow.

2. Measure Phase

• Objective: Collect data to establish a baseline for process performance.
• Process Mining: Utilize detailed process mining techniques to accurately measure current process performance. Focus on key metrics that align with the project objectives. This involves extracting and analyzing data from various sources to understand the flow and efficiency of the current processes.
• Process Design: Refine process redesigns based on insights gained from the collected data. Emphasize measurable aspects to ensure that any changes can be quantitatively assessed. Use BPMN diagrams to map out these redesigns and visualize potential improvements.
• Process Simulation: Implement basic simulations to predict the outcomes of minor process adjustments on key metrics. This helps in understanding the potential impact of changes before they are implemented in the real world.
• Capability: Establish an accurate measurement and baseline for the current process. This prepares the groundwork for in-depth analysis and ensures that subsequent phases are based on reliable data.

3. Analyze Phase

• Objective: Conduct an in-depth analysis of process performance data to identify the root causes of inefficiencies and variances.
• Process Mining: Employ advanced process mining techniques to uncover the root causes of deviations, bottlenecks, and inefficiencies within the workflow. This involves detailed analysis of process data to pinpoint where and why issues are occurring.
• Process Design & Process Simulation: Develop detailed models of potential solutions or redesigns. Use process simulation to test the impact of these changes on process performance, considering multiple scenarios and constraints. This helps in visualizing how proposed changes will affect the workflow before implementation.
• Capability: Identify root causes and test hypothetical solutions through simulation. This phase ensures that any proposed changes are based on solid data and have been thoroughly evaluated for their potential impact on the process.

4. Improve Phase

• Objective: Implement and validate the effectiveness of the chosen process improvements.
• Process Mining: Monitor the process changes in a live environment to collect immediate feedback on the impact of the improvements. This real-time data collection helps in understanding how the changes affect the workflow and identifying any unforeseen issues.
• Process Design & Process Simulation: Finalize the process redesign based on the analysis and simulated outcomes. Utilize simulations to refine and optimize the implementation strategy, ensuring that the changes lead to the desired improvements. This step involves creating detailed BPMN diagrams to map out the new process flow and using process modeling tools to test various scenarios.
• Capability: Continuous monitoring of improvements and adjustment of strategies based on immediate data feedback. This ensures that the process remains efficient and any necessary tweaks can be made promptly.

5. Control Phase

• Objective: Ensure the improvements are sustained over time, and the process remains within the desired performance thresholds.
• Process Mining: Continuously monitor the process post-implementation to ensure that improvements are maintained and to quickly identify any regressions. This involves using advanced process mining tools to track performance metrics and detect any deviations from the expected outcomes.
• Process Simulation: Regularly simulate “what-if” scenarios to proactively identify potential future improvements and react to changing business needs or external factors. This helps in maintaining the process’s efficiency and effectiveness over time.
• Capability: Long-term monitoring and continuous improvement through iterative simulations. This phase focuses on sustaining the gains achieved during the improvement phase and ensuring that the process adapts to any new challenges or opportunities.
