six sigma ninja process is a disciplined, statistics based data-driven improvement methodology for eliminating defects in a product, process or service. Six Sigma process can also be identified as a measure of process and performance that strives to run the business efficiently. This is the reason why Six Sigma certification has gradually gained popularity among hundreds of companies across the globe.
Six sigma process works on 6 levels (Sigma levels). Performance of a process is measured on sigma levels ranging from 1 to 6 basis its productivity. Once the current performance of a process is measured, the goal is to continuously improve the sigma level striving towards sigma 6. Even if the level doesn’t make it to sigma 6, only a point raise from sigma 4 to sigma 5 is enough to improve the business process.
What are the Six Sigma tools?
Six Sigma process makes use of some tools to determine the root cause of problems within an organization. Take a look at the following Six Sigma tools used for smooth and defect free outputs.
1. The 5 Whys
Often deployed as the analyzing phase of the six sigma process. At this stage, a lean six sigma full course black belt/ champion professional writes down the problems in a six sigma process and tries to figure out the reason behind the problem.
2. The 5s System
A method of organizing workplace materials for quicker access and better maintenance. These Ss are:
- Sort – Remove all unnecessary items
- Set in order – Organize remaining items
- Shine – Clean and inspect work station
- Standardise – Collate standards for Sort, Set in order and Shine
- Sustain - Implement and wait for results
3. Value Stream Mapping
The value stream mapping in the Six Sigma process shows the flow of materials and information in one of your processes and help to optimize the organizational flow. The aim is to eliminate non-value adding activities and make the process more concise. There a three value stream mapping as mentioned below:
- Value enabling activities
- Value-adding activities
- Non-value adding activities
4. Regression Analysis
Regression analysis is a statistical process for estimating and understanding the relationship between variables. It is used to define the mathematical relationship between an output and input variable and visualize the pattern to understand the workflow.
5. Pareto Chart
Often lauded as one of the most important six sigma tools, the Pareto chart graphically displays the difference between data groups. This will help the team to identify the problems in six sigma process.
6. FMEA
Failure modules and effects analysis (FMEA) helps the business to identify and eliminate the weak points in a six sigma process at an early stage. This six sigma tool is used to review components, assemblies and subsystems to identify failures, their causes and effects.
7. Six Sigma Certification Eligibility
There is no prescribed eligibility criteria to take up any of the Six Sigma certifications. However, certain amount of work experience and training is required by a candidate willing to take any of the certifications offered at various levels. Candidates pursuing the training programme have to take a test at the end of the training. Only those candidates who clear the test will be awarded the Six Sigma certifications basis the level of training they have opted for.
