FREE Lean Six Sigma Black Belt Certification Assessment Questions and Answers
People's performance both before and after training will be evaluated. Which test may be used to determine whether training improves workers?
The performance before and after training is compared using the Paired t test.
Which of the following is a chart that shows the measurement data's frequency distribution?
The frequency of occurrence of each measurement data is frequently represented by a histogram of the bar chart type.
Which chart is utilized to rank the CE matrix's greatest overall score according to?
The relative importance of the discrepancies between groups of data are graphically summarized and displayed using a pareto chart.
Which of the aforementioned activities adds value?
Testing, inspection, storage, and setup are all non-value-added activities that take time and effort. Process is the sole action that increases the value of the final product.
With what does Lean assist you?
Lean enables you to distinguish between operations that bring value and those that don't, as well as to cut back on the latter and get rid of waste.
Approximately 68% of the data in a normal distribution will fall within:
Approximately 68% of the data in a normal distribution are covered by the region under +/- 1 standard deviation.
What exactly does DFMEA mean?
The Failure Mode and Effects Analysis (FMEA) method is applied to product/service design specifically in DFMEA (Design Failure Mode and Effect Analysis).
The Risk Priority Number (RPN) in an FMEA exercise is determined as follows:
By multiplying severity by occurrence by detection, the risk priority number is generated.
Design for Test is a design method that has the following advantages:
The goal of the design technique known as "Design for Test" is to provide testing capabilities to the production of electronics. This method aims to demonstrate and validate the ability to identify product flaws.
Use of control charts is intended to:
The Control Chart's main functions are to create boundaries and visually depict the expected performance of any operation. It offers information on how a process performed over time, which may then be further assessed as necessary.
SIPOC stands for?
A team will utilize a SIPOC diagram to list all pertinent components of a process improvement project before work starts. It is often used at the Measure phase of the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) methodology to assist define a complicated project that may not have been effectively scoped.
Which of the following is a fundamental pre-requisite for Six Sigma success?
Make sure you have a clearly defined procedure before you start a Six Sigma project. If such a procedure is lacking, it is advised to create it before beginning the job.
What exactly does KPIV mean?
Key Process Input Value is referred to as KPIV. Fishbone diagrams typically provide insight into potential KPIVs for a model.
Accurate measurement is achieved when:
Repetition will aid in reducing variation between various measurements, and reproducibility will aid in reducing variation between measurements taken by various individuals. Both of these are beneficial, and when the divergence between the measured value and the real value is decreased, genuine measurement accuracy will be attained.
Which five components make into Kaizen?
Teamwork, personal discipline, raising morale, quality circles, and suggestions for improvement are the five components of kaizen.
What are the five principles of lean?
Identify Value, Map the Value Stream, Create Flow, Establish Pull, and Seek Perfection are the five guiding principles of lean manufacturing.
