Six Sigma is quality control program developed in 1986 by Motorola. Motorola first introduces it to tackle manufacturing defects and cycle time improvement. In today competitive market where the people are using product not only to take benefit of that product but use the value-added services also like mobile phone, people are more interested in checking what value-added services mobile service provider are providing. So, we can easily understand from the statement adding value to the existing product and services is the key of the success. Six Sigma is very essential in today’s world where the main business is on customer centric and entire ball game depends on satisfying the customer’s multiple needs in one place. As the process is bit complicated so there are chances of some faults/deviations/wastage. In the era of zero based budgeting, cost is one of the important factor in the enterprises. No body want to do the adverse variances in their budgeted V/S actual report. As the cost budget is limited so there is no place for faults/deviation. Here six sigma not only controls the deviations, it is providing frame work for nullifying the effect of the same.
As the name suggest “SIGMA”, it means standard deviation or standard error in statistic. It is clearly understanding from the name this method is dealing with the error and deviations and find the possible way to not only rectify it but abolish it from the process. Now a day Six Sigma has evolved into a more general business-management philosophy focused on meeting customer requirements, improving customer retention, and improving and sustaining business products and services. Six Sigma is applicable to all industries but mostly it is used in manufacturing Industry
SIX Sigma processes(DMAIC)
Entire six sigma philosophy is based on a principle called DMAIC.The ideology behind DMAIC is that a business can solve any seemingly unsolvable problem. There are 5 steps in DMAIC.
Define: -The first step of DMAIC is define. It means define the problem first. We need to first identify the problem, so hypothesis should be defined first. When we know our problem and our null hypothesis is ready then it is easy for us to address the same.
Measure: -The next of DMAIC is to measure the problem. It is very important for us to measure the actual problem what is the risk associates to us. If the effect is immediate and risk is very high then address of the problem is urgent. Measurement of the risk is helping us to follow the strategy i.e., prevention is better than cure.
Analyse: -Third step is analyzing the problem. After measurement it is very important for us to find out what is the step to solve the issue. For that reason we need to analyse the entire situation test the null hypothesis and analyse all the possible solutions.
Improve: -Take the necessary steps to improve the process.
Control: -Finally take corrective measures and final control.
So, in the current scenario Six Sigma is very important to find out error/deviation in the process and improve the entire process. It also helps in taking ownership control which will help to create the best possible value addition in the process and also create a “0” error system which will ultimately leads to create ultimate customer satisfaction and build a win-win relations between value provider and end users.
