What are Six Sigma Tools?
Plenty of six sigma tools are used to define, measure, analyze, improve, and control processes.
Let’s discuss the mainly used six sigma tools in the following.
List of Top Six Sigma Tools
Tool #1. Value Stream Mapping
This is a six sigma tool that uses a flowchart to outline the information as well as materials required for process improvement. Every flowchart has three core elements: process map, information, and timeline. With this flowchart, we can clearly visualize information such as time, delays, error rate, etc. Overall, we can streamline process flow with the necessary information required by using this six sigma tool.
Tool #2. FMEA
FMEA FMEA is the short form for Failure Modes and Effects Analysis. Proactiveness is the basic principle behind this six sigma tool. According to this method, you need to find potential failures in processes and implement corrective measures before any failure can happen. Besides, it is one of the cost-effective tools since it allows making corrections in processes before implementing them in a production environment.
Tool #3. Pareto Chart
Pareto Chart It is the six sigma tool that proposes the 20-80 rule. The significant thing about this rule is that only 20 % of efforts will generate 80 % of output. This tool helps to find the crucial processes that significantly impact the result of the business or projects. This is because focusing on the crucial processes will help to improve overall performance.
Similarly, we can find the processes that create more errors than others. So we can control them immediately to optimize processes. In short, this tool encourages clever work rather than hard work.
Tool #4. Histogram
Histogram In its basic form, it is the visual representation of the frequency distribution of data. With this six sigma tool, we can quickly identify the variations in a graph. Subsequently, we can locate where problems exist in processes so that we can rectify them with corrective measures. The significant thing in applying corrective measures is that we need to find the root causes accurately and then implement the measures. Only this approach will produce better results.
Tool #5.The 5 Whys
The 5 whys The basic principle behind this six sigma tool is asking ‘why’ five times repeatedly to dig out the root cause of a problem. This method helps to choose the most accurate solutions for problems. Mainly, you can solve complex problems efficiently and derive better solutions.
It is essential to note that although this method looks simple, the results are so powerful.
Tool #6. Fishbone Diagram
Fishbone Diagram It is the cause-and-effect visual tool. With this six sigma tool, you can find the root cause of problems. This tool binds mind mapping and brainstorming methods to determine the root cause of problems.
Tool #7. Kanban
Kanban Actually, Kanban means a graphic card. A Kanban board is usually made up of a series of graphic cards. Every Kanban board will have at least three vital parts: works completed, works in on-progress, and works to be completed. So, you can keep track of the work progress closely by using the tool. The main thing about this tool is that it draws limits for every process. As a whole, this six sigma tool encourages high-level focus and improves efficiency.
Tool #8. Kaizen
Kaizen The basic principle behind this six sigma tool is continuous improvement. This tool encourages improvements in small increments, which will produce significant results positively. In the same way, this tool aims to reduce redundancy and increase efficiency. Besides, Kaizen improves collaboration since it encourages the active participation of people.
Tool #9.Statistical Process Control (SPC)
This six sigma tool allows building control charts with which you can track the performance of improvements already applied to processes. With control charts, you can visualize and understand the progress of processes compared to the normal values.
In other words, this control chart tracks the progress of processes over time, which will help to identify the exact spot and degree of variations. So you can apply suitable corrective measures. Actually, these variations are known as special cause variations. Further, you need to identify the root cause for the variations and implement the corrective measures.
Tool #10.The 5S System
The 5S System 5S stands for Sort, Straighten, Shine, Standardise, and then Sustain. It is the six sigma tool that comes with a visual plan that is closely related to workstation optimization. Mainly, when you implement a new process, you need to modify your workstation in such a way that it simplifies implementing the new process. As a result, the work environment would become more feasible and conducive.
When it comes to software projects, you can delete unwanted files and folders, organize the needed files, standardize naming conventions, monitor the data flow, and so on – based on the 5S system.
Key Principles of Six Sigma
Essentially, six sigma tools are designed based on the following fundamental principles.
Principles of Six Sigma
Six Sigma Methodologies
Know that there are two six sigma methodologies as follows
Now, it’s time to dig into what DMAIC is.
It is the short form of Define, Measure, Analyse, Improve, and Control. These are the stages involved in the DMAIC method. You can use this method to correct a process that is already live. In other words, you can use this method when a process doesn’t meet the specified values.
If you want to know what each stage does, move on to the following.
Six Sigma Methodologies
First, you need to identify the quality goals based on customer expectations, desired values, industry standards, etc. Along with that, you need to prepare a problem statement, inputs as well as outputs of various processes, project scope, and other essential aspects.
This stage helps to understand the performance level of existing processes. To achieve this, you will measure all the parameters associated with the processes, such as cycle times, variance, inputs, outputs, etc. And with this, you can find the gap between the actual and target performance of the processes. It will allow you to take suitable corrective actions.
In this stage, you will identify the root cause for the process variations. You will achieve this by using analytic methods such as regression analysis, 5 Whys, Fishbone diagram, and others.
It is one of the crucial and longest stages in the six sigma methodology. This stage includes creating as well as implementing solutions using brainstorming and other innovative practices. Before implementing solutions, you need to carefully test and optimize them to improve the efficiency of processes.
It is the final stage in the six sigma process. In a way, it is a sustainability stage used to continue the performance of processes. This stage includes tracking processes, empowering people, updating documentation, reinforcing solutions, and so on.
It is the short form of Define, Measure, Analyse, Design, and then Validate. This method can create a new process and validate its efficiency.
