Six Sigma
Achieve Breakthrough Quality and Process Excellence
Looking to reduce defects, enhance customer satisfaction, and drive measurable results?
Need to improve your process consistency, reduce variation, and make data-driven decisions?
Discover how Six Sigma can help your organisation achieve operational excellence by combining statistical thinking with powerful process improvement tools. Whether you’re in manufacturing, services, finance, healthcare, or the public sector, Six Sigma equips your teams to solve problems, optimise processes, and deliver measurable impact.
Six Sigma (also written as 6 Sigma, 6 σ) is a data-driven methodology focused on improving process capability by reducing variation and eliminating defects. It empowers organisations to make better decisions using facts and data, and systematically drive improvements across departments and functions.
By eliminating variability and defects that undermine product and service quality, Six Sigma can bring about significant improvements in performance, profits, employee morale, product and service quality, and customer confidence.
At its core, Six Sigma follows the DMAIC framework:
- Define the problem and project goals
- Measure current performance and gather data
- Analyze the root causes of defects and variation
- Improve the process by implementing targeted solutions
- Control the future process to sustain the gains
Six Sigma starts by defining what is critical to quality and ends by producing superior products/services for the customer. It improves performance, decreases process variation, and in turn leads to defect reduction and vast improvement in profits, employee morale, and quality.
While traditional methods depend on measuring outputs and establishing control plans to shield customers from organisational defects, Six Sigma demands that problems be addressed at the root level, eliminating the need for unnecessary inspection and rework processes.
DMAIC
- Define: Define specific goals in achieving outcomes that are consistent with both your customer’s demands and your own business’s strategy. In essence, you are laying down a road map for accomplishment.
- Measure: Determining the baseline level is crucial to assessing the effectiveness of improvements. In the Measure step, measurements must be made and relevant data must be collected so that future comparisons can be made to determine whether or not improvement is achieved.
- Analyze: This step determines relationships and the factors of causality, which is critical when trying to find the root cause of a problem.
- Improve: Making improvements or optimizing your processes based on measurements and analysis can ensure that defects are lowered and processes are streamlined.
- Control: Control ensures that any variances stand out and are corrected before they can influence a process negatively, causing defects. It can be in the form of pilot runs to determine if the processes are capable, and then once data is collected, the process can transition into standard production. Continued measurement and analysis are required to keep processes on track and free of defects below the Six Sigma limit.
This proven methodology is widely used in industries worldwide to improve quality, productivity, and profitability.
