6 sigma construction12/31/2023 This methodology was pioneered by Motorola in the 1980’s and was embraced heavily by GE in the 1990’s, heavily utilized in all large scale manufacturing processes. Focused efforts on outputs critical to the customer will help reduce the variations, leading to financial gain for the organization. Six Sigma is a quality management philosophy and a methodology that focuses on reducing variation, measuring defects and improving the quality of products, processes and services. While it is inherent to have variability, companies should try to maintain it at the lowest levels possible in order to provide the best service to the customer. These additional expenditures could badly impact the profitability of the business and could even push an organization out of business. As a result, the organization has to incur additional expenses to correct these defects. Higher variability in product/service results in poor quality of product/service. Would these be acceptable to the client? The need to manage variability ![]() The quality of service offered was far below the set expectations. A project that was supposed to be delivered in 5 months but took around 10 months to complete. What if the variations are to the extent that is unacceptable to the client? Consider a few scenarios – the budget of the client was INR 50 lakh but the cost of construction happened to be INR 60 lakh. Buildings are the same, and construction quality differs from firm to firm and process to process. The purpose of specifying tolerance levels is to account for these variations. ![]() There is always an inherent variability associated with products and services. Do you think every product/service will be exactly the same as others in the same product/service line? Surely not. By following the five steps of Six Sigma, construction professionals can optimize processes, increase efficiency, and reduce errors, ultimately resulting in a higher-quality finished product.Organizations make income by offering products and services to their customers. Six Sigma practices in construction can help to improve project outcomes by identifying and addressing issues early in the project. It can also be used to improve the procurement process by ensuring that the materials and equipment are delivered on time and within budget. For example, Six Sigma can be used to optimize the design process by identifying and addressing design errors early in the project. Six Sigma practices can be applied to various aspects of construction projects, including design, procurement, construction, and commissioning. This step helps to identify any issues or problems early and take corrective action to avoid any negative impacts on the project. In construction, this involves monitoring the KPIs identified in the first step to ensure that the project is progressing as planned. The fifth and final step in Six Sigma is to control the process or system to ensure that the improvements made are sustained over time. This step helps to optimize the process and improve project outcomes. In construction, this involves implementing changes to address the root cause of any issues or problems identified in the previous step. The fourth step in Six Sigma is to improve the process or system. This step helps to prioritize improvements that will have the most significant impact on the project. In construction, this involves identifying the root cause of any issues or problems and determining the impact of these issues on the project's overall performance. The third step in Six Sigma is to analyze the data collected in the previous step. This step helps to identify any gaps between the current performance and the desired performance. ![]() In construction, this involves collecting data on various aspects of the project, such as project schedule, budget, quality, and safety. The next step in Six Sigma is to measure the current performance of the process or system. This step helps to establish a clear understanding of the project's requirements and ensures that everyone is working towards the same goals. In construction, this involves identifying the scope of the project, setting goals and objectives, and determining the key performance indicators (KPIs) to measure progress. The first step in Six Sigma is to define the problem or project. In this article, we will discuss the key practices of Six Sigma in construction. Six Sigma practices in construction aim to improve processes, increase efficiency, and reduce errors, which ultimately results in a higher-quality finished product. However, it has now been adapted to various industries, including the construction industry. Six Sigma is a methodology that originated in the manufacturing industry to improve quality and reduce defects.
