Six Sigma Tools Used in Construction
In Six Sigma, the DMAIC (Define, Measure, Analyze, Improve and Control) method is a popular approach for process improvement. However, Six Sigma methodology is not limited to DMAIC. There are several Six Sigma tools that can be utilized in a construction project for error reduction or defect minimization. Here are some Six Sigma tools that are often used in the construction industry:
Mistake Proofing
Mistake proofing is a technique that enables construction workers to avoid potential mistakes in a process. It is also called Poka-yoke, which means “mistake-proofing” in Japanese. Poka-yoke techniques can be used to identify any specific risks or issues in the construction process and eliminate them before they occur. In construction, this can mean the installation of sensor equipment that detects deviations from the correct installation process.
Control Charts
Control charts are tools that help to monitor changes in a process over time. They allow workers to quickly see any changes in quality that might affect the outcome of a construction project. These charts are also useful for identifying trends and patterns and predicting when changes might occur. Statistical process control is a use of control charts to identify when changes need to be made in order to maintain the quality goals.
“Six Sigma methodology is not based on applying a one-size-fits-all solution. Rather, assesses an individual project and selects tools that are appropriate for the goal of the project.”
Process Flow Mapping
Process flow mapping is a Six Sigma technique that can be employed to identify the steps involved in any process. It visually displays the sequence of tasks required to complete a process. In construction, the project manager can use process flow mapping to identify the tasks that have a high potential for error. They can also pinpoint where any delays or bottlenecks in the construction might occur and take action to prevent them from happening.
Kaizen
Kaizen is the philosophy of continuous improvement. It encourages workers to continuously seek improvements to a process, whether it is by reducing defects or removing inefficiencies. Kaizen events are short-term projects that aim to make specific improvements in the construction process. With a Kaizen event, the workers examine the existing process, identify areas for improvement, and then implement new approaches to resolve those issues. Kaizen techniques facilitate the fine-tuning of processes and procedures, eliminating unnecessary waste and improving efficiency.
