E. I, II, and IV only
Explanation:
Six sigma is a management technique that involves measuring the number of defective products resulting from production activities, and carefully undergoing certain processes to reduce these defects and improve quality.
The DMAIC cycle is an important process when using the six sigma technique. It involves;
• Defining the goals and objectives to be achieved and problems to be fixed.
• Measuring the production process to see how it currently performs and gathering data on defective products.
• Analysing the processes to find root causes of problems and possible causes of defects.
• Improving the process by implementing carefully formed plans which will help reduce defects.
• Controlling how the new processes are implemented to yield and sustain favorable results and deliver value to customers.
Six sigma aims to remove variations from business processes to reduce product defects and improve quality.
