What are measures of central tendency?

Steps and workflow of central tendency point to a single value that tries to define a set of data. It performs this by figuring out the central point of that data set. Also called as measures of central location, it is basically a calculation that tells us where the middle of a data set is.

Measures of central tendency is the core of the data studying process. The technical person working on the Six Sigma process, studies the data and statistics from the measures of central tendency to proceed further.

Explain different kinds of variations in Six Sigma.

– The mean, also called as the average, is the most used of all the measures of central tendency. Since the values are counted, the tools are applicable for a limited number of applications. The variations are measured as well as compared using the mean techniques of mathematics in this process. lean six sigma black belt certification

– Positional averages are the calculative position of a given record in a number series, arranged in ascending or descending order. This basically works by getting the highest value and the lowest value in a number series, adding them together and then dividing the value by two to get averages like how most average calculation works. It divides the series group into two equal parts. One part holding all greater numbers from the series, and the rest of the values which are less than median.

– The mode is basically a value which occurs again and again like a loop. It is an actual value, where other items are concentrated around and they differ as the value changes due to its regular occurrence.

– Range depends on the highest rate and lowest values for a specific data range. It is basically the length of the number sequence or data set which has a specific value.

Thoroughly differentiate between the Six Sigma DMAIC and DMADV methodologies.

DMAIC stands for Define, Measure, Analize, Improve, and Control where DMADV stands for Define, Measure, Analize, Design, and Verify.

When a new and non-existing product needs to be developed and an entirely new business process needs to be developed for product development, organization prefer DMADV methodology whereas, if a process or product already exists but still needs to meet the standard of Six Sigma level and customer expectations, DMAIC method is used. From these two methods, DMAIC is the most common and extensively used methodology for optimization of product making processes. Old company using old process optimizing tools, are usually migrate to Six Sigma by DMAIC methodology to optimize their product making process.

What is Cpk and Ppk?

Cpk stands for process capability index which helps to calculate how close a process or function is executing to its specification limits, compared to the default variability of that function.

Whereas, Ppk stands for a process performance index which checks if the sample generated from the process is capable of meeting customer’s characteristics that are Critical To Quality or not. The difference lies in verifying capability to the specification limit and verifying the performance of the process.

What is Lean Six Sigma?

Lean Six Sigma is a methodology exclusively meant for the improvement of performance that involves removing unwanted and unexplainable stuff that does not add any absolute value to the process and also helps in the reduction of the variables. This idea depends on a collaborative team work and effort. Lean Six Sigma promises a high-quality output and immense customer satisfaction.

Here are some of the lean tools used extensively: Kaizen, Poka-yoke, FMEA, Value Stream Mapping

Explain FMEA

FMEA stands for, Failure Mode Effects Analysis. It is a tool to identify and locate risks within a Six Sigma process or product which is priorities to make the error correction process accurate. This tool helps to take the essential steps for mitigating the risk.

Explain ARMI or RASI

ARMI stands for Approver, Resource, Member, and Interested Party. It is basically a tool which is meant for the employee who are assigned specific task and their roles and responsibility to that particular project. This tool can allocate task to a specific user and act as a reminder and notifier to the respective user when a project is assigned to them.

What is the Pareto Principle?

The Pareto principle or the 80-20 Rule states that, for any occurrence, nearly 80 percent of the results evaluate from 20 percent of the problems. It focuses on the 20 percent of the trial outcome to validate 80 percent of the result. We can also see it as 20 percent of the highly effective data is more reliable and valuable than the 80 percent of the data.
