Lean Six Sigma Yellow Belt Sample Exam Questions 

Use these example answers with a set of practice questions to prepare for your Lean Six Sigma Yellow Belt certification. This abstract will make it possible for you to find the key points of the material and understand the principles of Lean Six Sigma. 

1) What is Lean Six Sigma? 

Sample Answer: The Lean Six Sigma is an approach that contains the principles of Lean. It focuses on excluding waste and improving efficiency, using Six Sigma techniques, which aim to reduce variation and defects in processes.
 

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 

Sample Answer: The abbreviation DMAIC mostly denotes Define, Measure, Analyse, Improve, and Control.
 

It shows the formal process that forms the basis of problem resolution within Six Sigma projects. In addition, it draws the focus on identification, examination, and refinement of processes for attainment of results and requirements of customers or their expectations.

4) What is a Process Flow Diagram (PFD)? 

Sample Answer: A Process Flow Diagram (PFD) is the diagrammatic presentation of a process showing sequences of constituent steps, activities, and interactivity. It shows the flow of material, information, and resources through input-conversion-output. 

5) What constitutes Lean methodology? 

Sample Answer: Lean methodology involves those principles and practices targeting value maximisation with wastes minimised in operations.
 

These focus on the continuous improvement of the operations, respect for people, and client focus with an aim of reaching the operational excellence level. 

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 technique 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. This, in turn, will improve quality, efficiency, and customer satisfaction. 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, output, and the other executed activities. It is very essential in pinpointing the wastes, constraints, or areas of focus on value stream map.
