2) Define a control plan
Sample Answer: The control plan is a document that describes the necessary actions and procedures needed to ensure that the retained process is under control and can meet the requirements for quality. It includes data such as the key process indicators, control limits, and what contingency plans to take during the deviation.
3) Describe the DMAIC process

6) Explain the concept of a Control Chart
Sample Answer: A Control Chart is a graphic representation of a format used in the inspection of behaviour performance relative to time. Usually, it comprises plotting the data points against control limits so that one can easily recognise trends, patterns, or deviations.
7) What is Statistical Process Control (SPC)?
Sample Answer: Statistical Process Control (SPC) is a method using statistical techniques for control, monitoring, and improving the process. This method involves analysing process data to distinguish between special-cause variation and the common-cause variation inherent to the process.

8) What is the purpose of the Six Sigma Methodology?
Sample Answer: The Six Sigma methodology is a way of trying to improve quality by reducing variations and defects within processes.

It is about systematically trying to look for the source of that variation and trying to eliminate the same for flawless or near-perfect results.
9) What is the purpose of a Fishbone Diagram (Ishikawa Diagram)?
Sample Answer: The purpose of a Fishbone Diagram, also known as an Ishikawa Diagram, is to visually represent the potential causes of a problem or effect. It helps identify root causes by categorising contributing factors into major categories, such as people, processes, equipment, environment, and management.
10) What information does a Value Stream Map (VSM) convey?
Sample Answer: A Value Stream Map or VSM is a graphical representation that resembles a map and describes the existing flow, main activities, inputs, outputs, and other executed activities. It is essential in pinpointing the wastes, constraints, or areas of focus on the value stream map.
