Final answer:
Six Sigma is a methodology used in business and manufacturing to reduce defects and variability in processes, aiming for a target of 3.4 defects per million opportunities. It adopts information theoretic approaches, and is known for being adaptable and easy to communicate, aiming for improvement in large scale processes.
Step-by-step explanation:
Six Sigma is a set of techniques and tools for process improvement that is highly adaptable and widely applicable to large scale processes. It involves methodologies to reduce defects and variability in manufacturing and business processes, hence improving quality and efficiency. The key principle of Six Sigma is that it takes into account 3.4 defects per million opportunities as the norm for process variation, which relates to the Six Sigma level of performance.
Having a deep understanding of process variation is central to the Six Sigma approach. This business strategy uses information theoretic approaches to analyze the data, making the results easy to interpret and communicate with stakeholders. The goal of Six Sigma is to identify and eliminate causes of defects and minimize variability in business and manufacturing processes to enhance performance and customer satisfaction.
