Organizations use process improvement techniques to enhance operations, improve productivity and profitability, and adapt to evolving business needs. In the manufacturing industry, organizations use the Six Sigma methodology to minimize time, defects, and variations in organizational processes. This methodology aims to achieve improved end products through a structured framework that relies on a five-stage process known as DMAIC (define, measure, analyze, improve, and control).
The “define” stage involves organizations employing a customer-centric approach to identify problems in the manufacturing process and areas to improve. The organization then sets clear goаls and identifies the resources necessary to achieve the desired outcome. Afterward, leadership maps out the process with the input of stakeholders to ensure it stays on track. Essential aspects of this stage include research on what customers want, the project's scope charter (encompassing budget, driving motivation, and focus), and the timeline.
The next stage is the “measure” phase, wherein an organization will assess the current manufacturing metrics and establish a data-backed baseline for improvement. This stage also involves quantifying the problem and contextualizing how much money the company loses due to extended execution times, mistakes, or inefficient flows.
Once the organization has identified and quantified the problem, it conducts an analysis to determine the root cause. The “analysis” phase involves looking at the process to identify any steps prone to error, or redundant steps that can be eliminated to streamline the workflow. A successful Six Sigma analysis requires a skilled business process modeler and a centralized location to store all processes, along with predictive and simulation capabilities.
The next stage, “improvement,” is where project management teams act to solve the problems identified during analysis. They deploy different piloting and testing variables to refine and adjust the process until they find solutions. They then implement these solutions to address the root causes of the process problems and to reduce or minimize defects through automation, optimization, or modernization.
The “control” phase, the final stage of the Six Sigma technique, involves monitoring and assessing the improved process to ensure it consistently delivers better outputs and faster execution times. In addition to tracking the process in this stage, the organization's project management teams may need to revisit it regularly and apply the other four steps to maintain operational excellence. Doing so also helps them achieve greater customer satisfaction.
As with any process, Six Sigma has various challenges. For instance, since this technique relies heavily on statistical tools, organizations need a statistics or data analytics expert to guide these imperative toolsets. Also, organizational members may not understand the technical aspects of Six Sigma, resulting in failure to allocate enough time, resources, or staff to support it.
On the other hand, the process has numerous benefits for organizations besides bolstering productivity and improving quality. It can help organizations increase their throughput rates by identifying and eliminating root causes of process problems through precise data analysis. It also provides better visibility of the complete production cycle and reduces instances of major product or process defects. Moreover, by improving efficiency, the Six Sigma technique minimizes operating costs and allows companies to save on expenses.
