Six Sigma In 9 Minutes | What Is Six Sigma? | Six Sigma Explained | Six Sigma Training | Simplilearn

imagine you've been tasked with a really important project at work the company you're working for produces luxury cars the production numbers are going down and a lesser number of cars are getting manufactured each day there also seems to be an issue with the quality of the windshield wipers that go on these cars the question you are faced with is there a way for the company to stop the stall in production and increase the production per day from 1 000 to 2 000 also is there a way to find out what's causing the drop in the

wiper quality there is six sigma six sigma gives you the tools and techniques to determine what's making the manufacturing process slow down how you can eliminate the delays improve the process and fix further issues along the way the concept was introduced in 1980 by bill smith while working for motorola since then six sigma has seen worldwide adoption six sigma aims to reduce the time defects and variability experienced by processes in an organization thanks to six sigma you can produce an effect-free product 99.9996 percent of the time allowing only 3.4 errors per 1 million opportunities six

sigma also increases customer loyalty towards the brand improves employee morale leading to higher productivity six sigma has two major methodologies dmaic and dmadv let's look at the first methodology dmaic is an acronym for define measure analyze improve and control let's have a look at each of these stages individually and how it relates to your earlier problem in the define phase you determine what issues you're facing what your opportunities for improvement are and what the customer requires of you here you look at the process as a whole and determine the issues with the manufacturing process in

this case finding out why the cars had varying windshield wiper quality and how to optimize the current process to manufacture more cars in the measure phase you determine how the process is performing currently in its unaltered state you determine the current number of cars that are manufactured in a day in the current scenario 1 000 cars are manufactured in a day and each of these cars are outfitted with a pair of windshield wipers by one of 30 machines used some of the metrics measured are how many cars are produced in a day time taken to

assemble a car how many windshield wipers were attached in a day time that takes them to do so defects detected from each machine on assembly completion and so on following this in the analyze phase you determine what caused the defect or variation on analyzing previous data you find out that one of the machines that installed the windshield wiper was not performing as well as it was supposed to production was taking longer since the car chassis was being moved across the different locations slower as cranes had to individually pick and drop the frame this was because

the wheels were attached to the car only in the last stage next in the improve phase you make changes to the manufacturing process and ensure the defects are addressed you replaced the faulty machines that installed the windshield wiper with another one you also find a way to save time by attaching wheels on the frame in the initial stages of the manufacturing process unlike how it was done earlier now the car can be moved across the assembly area faster and finally in the control phase you make regular adjustments to control new processes and future performance based

on the changes made the company was able to reduce production time and manufacture about 2 000 cars a day with a higher quality of output dmaic is one of the most commonly used methodologies in the world it focuses on improving the existing products of the organization the second methodology is dmadv which is shored for define measure analyze design and verify it is used when the company has to create a new product or service from scratch it is also called dfss or design for six sigma let's take the scenario where the company decides to build a

new model a sports car in the define phase you define the requirements of the customer based on inputs from customers historical data industry research you determine what you need to ensure your car becomes a success the data collected indicates customers are drawn to cars which can achieve more than 150 miles per hour customers are also more inclined towards cars which have v6 engines and an aerodynamic frame then in the measure phase you use the customer's requirements to create a specification this specification helps define the product in a measurable method so that data can be collected

and compared with specific requirements some of the major specifications that you focus on are the top speed engine type and type of frame in the analyze phase you analyze the product to determine whether there are better ways to achieve the desired results areas of improvement are determined and tested based on the analysis of the prototype created in this phase you find that the product satisfies just about all of the customer requirements except the top speed so research begins on an aluminum alloy that could possibly meet the speed requirements of the customer following this the design

phase based on the learnings from the analysis phase the new process or product is designed revisions are made to the model and the car is manufactured with the new material the analysis phase is repeated based on the new design you also bring a focus group and see how they receive it based on their feedback further changes are made and finally in the verify phase you check whether the end result meets or exceeds customer requirements once you launch your brand new sports card you collect customer feedback and incorporate it into future designs and guess what your

customers are loving the new design and that is dmadv for you six sigma has also found success in a number of different industries the petrochemical healthcare banking government and software are some of the industries that have utilized the concepts of six sigma to achieve their business goals another commonly used methodology adopted by companies around the world is lean lean is a methodology that aims to remove any part of the process that does not bring value to the customer it means doing more with less while doing it better the philosophy behind lean comes from the japanese

manufacturing industry by bob hartman who at the time was part of toyota since then across the world services and manufacturing organizations have incorporated lean within their businesses but what if you could have the best of both worlds a combination of both six sigma and length that's lean six sigma before we get into lean six sigma we've got a quiz for you what methodology is used by companies when they want to release a new product created from scratch a design measure analyze define verify b define measure analyze design verify c demand measure analyze improve control d

define measure analyze improve control leave your answers in the comments section below for a chance to be one of three people to win an amazon voucher now let's get back to lean six sigma lean six sigma is a methodology that focuses on eliminating problems removing inefficiencies in waste while improving the working conditions to ensure the customer's needs are better satisfied it combines the tools methods and principles of lean and six sigma we'll have another video detailing the process of lean six sigma very soon we hope you found this informative and helpful if you enjoyed this
