Six Sigma Green Belt (SSGB) Interview Questions
When we think of a job interview, we have a lot of questions. What will we do about it? Will it be difficult? It can appear more difficult than the job itself, and if the interview is technical, we will have a lot of questions on our minds. At this point, we must understand that the most important factor in the interview is not only our knowledge but also our confidence and attitude toward the interview questions. We may not always know the solution, but that’s okay. Nobody has all the answers!
We must make every effort to answer all of the questions about which we are certain. If someone is unsure about anything, they must accept it as fact. The questions asked in a Six Sigma Green Belt (SSGB) interview vary depending on the professional level for which you are applying. Therefore let’s look at some top questions:
1. What would you do if you were given a VOC/VOP?
After receiving client complaints and the Voice of the Process, we must conduct a Critical to Quality assessment, which allows us to convert consumer feedback into metrics. Six Sigma would take real-world issues and turn them into statistical problems with statistically derived answers.
2. What exactly is SIPOC?
It is a tool that allows you to see the entire process in one glance, including Suppliers, Inputs, Process, Output, and Customers.
3. What are the Milestones?
The methodology used in the Six Sigma process is either DMAIC or DMADV, and each stage should have certain time durations. Milestones provide the time duration limit for each stage, and extending the time limitations requires consent from stakeholders.
4. What does ARMI or RASIC stand for?
The entire Six Sigma team learns who the authorize person is, who is responsible for the project, who should be a consultant, and who should be informed via ARMI or RASIC, ensuring that there are no conflicts at work.
5.How should the problem statement be define?
The problem should be clear and concise, with metrics provide to make it easier for stakeholders to comprehend what will happen if the problem is not solved; future ramifications should also be discuss with stakeholders.
6.How will the data be collected?
First, we must understand Y = F(x), which means we must understand what all factors have an impact on Y, and correspondingly, we must stratify our data collection.
7.What is the Ishikawa diagram, exactly?
The cause and effect diagram, or fishbone diagram, is another name for the Ishikawa diagram. We use this after the brainstorming session to categorise all of the challenges into 6 Ms (manufacturing) and 4 Ps (productivity) (service industries).
8.What are the different kinds of data?
There are two categories of data: quantitative and qualitative. Continuous data falls under the quantitative data category, while discrete data falls under the qualitative data category.
9.What exactly is MSA?
MSA stands for Measurement System Analysis, and it is use to determine whether or not our measurement system is correct. We conduct attribute analysis for service businesses.
10. What criteria should you use to select projects and issues?
It is require that you mention VOC or VOP. Clients or customers should provide VOC by providing reactive feedback, conducting surveys, or evaluating the process. This method can be use to identify criteria such as customer discontent with items or services.
11.What is the project’s scope?
The project scope is use to set project boundaries so that the team may focus on what is inside the boundary and what is beyond the border is not a concern for the project. As a result, boundaries can be set around a single process, location, people, or time period.
12. What are your plans for defining the problem statement?
The problem statement that must be define must be concise and unambiguous. Also, if the problem has not been fix, the problem statement should be specified in metrics so that stakeholders can comprehend it. Future ramifications should also be discuss with stakeholders.
13. What is a Pareto graph?
One of the most widely used tools in six sigma and quality management is the Pareto Chart. You should describe the Pareto analysis and define each feature of the Pareto chart to prioritize the issues or causes. You must also indicate the number of data points required for Pareto, in circumstances when the Pareto ratio is 50:50. Giving all of the facts shows that you understand every facet of Pareto. You must also discuss hypothesis testing, which is one of the most important aspects. The hypothesis tests perform, their implementation, the significance of these tests, and the necessity for regression must all be consider. You must provide complete information, including test results and what was seen during the tests.
14.What is COQ’s principal function?
COQ is largely use to comprehend, analyse, and enhance quality outcomes. COQ can be utilize both on the shop floor and as a management tool. It can also be used as a benchmarking indices and a standard metric to compare an organization’s performance to that of another similar organisation.
15. How is the VOC information collected?
Direct interviews with customers, such as site intercepts, personal interviews, focus groups, customer feedback forms, or structure online surveys, and indirect interviews with representatives, such as sales people or customer service representatives, who interact with customers and report on their needs, can be use to gather VOC information.
16. Which waste removal method emphasises workplace organisation?
5S stands for seiri, seiton, seiso, seiketsu, and shitsuke, which are five measures for developing and maintaining a clutter-free, clean, organised, safe, and high-performance workplace.
17. For two variables linearly related as y=2x, what is the coefficient of correlation?
It is assumed that two variables are linearly connecte as y=2x, and that y is twice the value of x. As a result, a positive correlation coefficient is obtained, and the resultant correlation coefficient will be +1 for any given value of x.
18.CTQs are use in which IDOV step to calculate the tolerance level of a certain business process?
CTQs are use in the optimise phase to calculate the tolerance level of a given business process using simulation tools. It anticipates a business process’s performance capabilities by optimising existing design and proposing alternative design features.
19. Which bar chart depicts numerical or measurement data frequencies?
The histogram depicts data frequencies as consecutive rectangles created over intervals with an area proportional to the number of observations in the interval. They’re frequency column graphs with a minimum of 50-100 data points that show a static picture of process dynamics. The number of data points that fall within a specific bar, interval, or frequency defines it.
20. What is the purpose of the solution piloting?
The goal of piloting solutions is to evaluate their impact in a control group context, and then make required changes to the final solution based on the qualitative and quantitative results.
21.In DMAIC, which phases use the DOE technique?
Improve phase-selection techniques such as the Design of Experiment (DOE). It is solely focus on bringing improvements to the solution’s design, testing, and implementation. It entails gathering statistically verified results from an ongoing research or pilot, developing an improvement plan, updating stakeholder assessments, amending the business case with investment ROI, assessing risk, and adding new process capabilities.
22. What is the procedure for gathering data for a Six Sigma Green Belt project?
The factors affecting the output function Y=f(x) that decide the data to be gather for a Six Sigma Green Belt project determine the data to be collected for the six sigma green belt project.
23. In a Six Sigma Green Belt project, what do you mean by MSA?
MSA is for Measuring System Analysis and refers to the examination of a measurement system for several parameters such as accuracy.
24. What exactly is a Tree Diagram?
A chart that shows how a topic is split down into sub-concepts with increasing levels of depth.
25. In a six-sigma project, what is the function of the Process Owner?
In a six sigma project, the Process Owner’s duty is to: 1. They must offer the inputs right at the start of the procedure. 2. They are expect to work closely with the Project Manager and validate the requirements that have been acquire. 3. They are in charge of the enhanced six-sigma process.
26. In a Six Sigma Green Belt project, what does Gauge R & R mean?
Repeatability and reproducibility are added to the R & R. The R&R Gauge is use to determine the difference between repeatability and reproducibility.
27. In a six-sigma green belt project, what is normal distribution?
Data is centred around a central value without bias in the normal distribution or bell curve. It is defined by the same mean, median, and mode values, as well as symmetry around the centre with 50% of values less and greater than the mean.
28. How does Lean Six Sigma work?
Combining lean and six sigma strategies to eliminate waste and variability in a process or product is known as Lean Six Sigma.
29. Distinguish between the control and run charts.
A run chart shows the variance of a particular data group across time to demonstrate process trends and shifts. A control chart is similar to a run chart, but it features UCL and LCL with a centerline, and it indicates whether the process is under control, moving in the right direction, or the output is within acceptable parameters.
30. In six sigma, what is OEE?
Overall Equipment Effectiveness (OEE) is a measurement of whether planned production time is productive or how quickly production without interruption delivers the required commodities. (Good Count of Goods Without Defects Ideal Cycle Time)/ Planned Production Time.
