So, you have been working in the field of Quality Management for quite some time now, and you feel that it’s time to start earning a little more than you are now. In order to add something fresh in your CV, you learn all about Six Sigma. The next part is sitting for an interview, and here’s where you get a little nervous. Isn’t it?
Well, Let me tell you, that’s completely natural. No matter how confident we are about ourselves or how much of corporate experience we have, interviews always give us a little heebie-jeebies. And on top of everything, you just learned a new skill! Who knows what kind of Six Sigma questions they are going to ask you?
To know that, there’s a little secret you need to know. No matter if you are a Six Sigma Green Belt Certified, Six Sigma Yellow Belt Certified of Six Sigma Black Belt Certified, at the interview table the part interviewers really love to ask you about is the basics of Six Sigma. Hence, we have fetched out 20 most commonly asked Six Sigma interview questions for you. Have a look!
Ans. Six Sigma is a set of techniques and tools for process improvement. Six Sigma strategies seek to improve the quality of the output of a process by identifying and removing the causes of defects and minimizing impact variability in manufacturing and business processes. It uses a set of quality management methods, mainly empirical, statistical methods, and creates a special infrastructure of people within the organization who are experts in these methods. Each Six Sigma project carried out within an organization follows a defined sequence of steps and has specific value targets, for example: reduce process cycle time, reduce pollution, reduce costs, increase customer satisfaction, and increase profits.
Ans. Mainly 4 variations are used in six sigma process:
Ans. The DMAIC project methodology has five phases:
On the other hand, DMADV methodologies five phases are:
Ans Fishbone or Ishikawa diagram is a visualization tool for categorizing the potential causes of a problem in order to identify its root causes.
Ans. The load testing process is a process of putting your demand on a software system or computing and measuring its process.
Ans. Performance Testing is a type of software testing that can be carried out to measure the system performance in terms of sensitivity, reactivity, and stability under a particular workload.
On the other hand, The load testing process is a process of putting your demand on a software system or computing and measuring its process.
Ans. The 3 key elements for the six sigma process improvement are customer, process, and employees.
Ans. The top-down approach is one of the processes within the Six Sigma implementation. This approach is aligned with business strategy and customer needs. Although, the major disadvantage of this process is its scope is very broad and at the same time it is difficult to execute it in a specified amount of time.
Ans. FMEA is an acronym for Failure Modes and Effect Analysis. FMEA is a risk assessment tool, that evaluates the severity, occurrence, and detection of risks to prioritize the most urgent ones.
Ans. The 3 steps for Root cause analysis are:
Ans. Six Sigma follows the DMAIC methodology to reduce waste. On the other hand, Lean uses these following 7 steps:
Ans. Lean Six Sigma is a method that relies on a collaborative team effort to improve performance by systematically removing waste and reducing variation. It combines lean manufacturing/lean enterprise and Six Sigma to eliminate the eight kinds of waste: Defects, Over-Production, Waiting, Non-Utilized Talent, Transportation, Inventory, Motion, and Extra-Processing.
Ans. Cpk stands for process capability index. It measures how close a process is running to its specification limits, relative to the natural variability of the process.
On the other hand, Ppk stands for a process performance index that verifies if the sample has been generated from the process is capable of meeting Customer CTQs or not.
Ans. Some Lean Six Sigma tools are:
Ans. DFSS stands for Design For Six Sigma. It is a business process management method related to traditional Six Sigma and is used in many industries, like finance, marketing, basic engineering, process industries, waste management, and electronics.
Ans. A data collection plan a plan to collect the necessary data. The main reason to collect data is to understand the current process and portray possible improvement suggestions. The data can be collected from three different primary sources they are as follows:
A Histogram represents the frequency distribution of numeric data, while a Boxplot summarizes the important aspects of continuous data distribution.
Ans. VSM stands for Value Stream Mapping. This is a methodology used to eliminate wastes from a process and map the flow of information required to deliver a product or service.
MSA stands for Measurement System Analysis. One can use MSA to check if a measurement system is accurate. It evaluates a system’s accuracy, precision, and stability.
Ans. SIPOC stands for Suppliers Input Process Output Customers.
It defines that a process can be summarized as a series of consecutive steps and activities that are executed in a timely manner to get a definite output.
So, we guess that should help you out during your big hike. Do you know what else can help you? A Six Sigma certification! Go for one, and thank us later when your Six Sigma Certification proves to be a real sixer!
