Today we are talking about Six Sigma Methodology . Six Sigma has two methods DMAIC and DMADV, each with its own set of recommended procedures to be implemented for business transformation. Six Sigma uses two different sets of methodology as lenses to examine and address complementary aspects of business processes. Each method has its own data and tools, through which it can be used to improve business processes.
What is DMAIC?
DMAIC is a data-driven approach that is used to improve existing customers or services, and also to improve customer satisfaction. DMAIC is used in a product manufacturing organization or any service delivery company.
DMAIC has five steps
D – Define
I – improve
What is DMADV?
DMADV is a part of Six Sigma Methodology design, DMADV is used to redesign the processes of product manufacturer or service delivery. Remember DMADV is employed when existing processes do not meet customer requirements, meaning DMADV is used to replace your existing processes, or even if your product or project needs to be developed DMADV Is required.
DMADV has five steps:
Difference Between DMAIC and DMADV
DMAIC is used, or will be, when you are trying to improve or develop a process that already exists, meaning your product or If there is a need to improve or develop a little project.
DMADV is used when redesign is to redesign your product or project. By the way, the purpose of both the methods is the same, to solve the problem of your business in a complete way.
The six Sigma process begins with a customer-centric approach.
stage 1: Business problem is defined from the customer’s point of view.
stage 2: The target has been set. What do you want to achieve What resources will you use to achieve the goal?
stage 3: map the process. Together with stakeholders verify whether you are on the right track.
MEASURE– In this, you need the data of the instruments used to make measurements, and also need to know the answers to some questions. How can we improve? How can we determine this?
stage 1: Measure your problem data with data on how to improve.
stage 2: Evaluate the data system to be improved, then you will know whether it can help you achieve your result or not?
This is the process to find the affected Variable, which enables us to analyze.
stage1: 100 percent Determine if your process is efficient and effective, can the process help you achieve what you want?
stage 2: Set your goals. For example, reduce defective items by 20%.
stage 3: Identify differences using your old data.
This process examines how the effect of your old data changes to the new data, this stage is where you identify how you can improve the process by implementing it.
Stage 1: identify possible causes.
Stage 2: Discover the relationship between Variable.
In this final stage, you determine whether the performance and purpose identified in the previous stage are implemented well, and whether the designed improvements are sustainable.
stage 1: Validate the measurement system used.
stage 2: establish process capability. Whether the goal is being met or not? For example, is the goal of reducing defective items up to 20 percent achievable?
stage 3: Once the previous stage is satisfied, implement the process.
Six sigma technique
The Six sigma method also uses a mixture of Proven qualification and quantitative techniques to achieve desired results.
A : Brainstorming
B : Root cause analysis
C : Voice of the customer
D: The 5s system
G: Poka -Yoka / Mistake proofing
H: Value Strem Maping
Brainstorming is an important process of any problem solving method and is often used in the “improvement” phase of the DMAIC method.
Before starting any tool, it must be a necessary process. Create a group and brainstorm and sit with everyone and creatively raise the problem and then implement it.
Root Cause Analysis/The 5 Whys
This technique helps to get to the root of the problems under consideration, and is used in the “analysis” phase of the DMAIC cycle.
5why In this technique, the question of “why” is asked repeatedly, eventually leading to the main issue. Although “five” is a rule of thumb, the actual number of questions can be more or less, whatever it takes to get clarity.
Voice of the Customer
It is a process used to capture the “voice of the customer” or the customer’s response through internal or external means. The aim of technology is to provide the best products and services to the customer.
It captures the changing needs of the customer in direct and indirect ways. The voice of the customer technique is used in the “Defined” phase, usually to address the problem.
The 5S System
The purpose of the 5S system is to remove waste and remove obstacles from unskilled equipment, equipment, or resources in the workplace. The five stages used are ciri (sort), citan (set in order), ciso (shine), csetsu (standardized), and shitsuke (susten). The 5S system will be known to many of you and we have also written a blog.
Kaizen (Continuous Improvement)
Kaizen technology is a powerful strategy, which powers a continuous engine to improve business. It makes it a practice to continuously monitor, identify and implement reforms.
This is a particularly useful practice for the manufacturing sector. Ensures collective and ongoing improvement, and helps make immediate changes.
Poka-yoke (Mistake Proofing)
The name of this technique comes from Japanese phrases, meaning “to avoid errors,” and prevents the possibility of mistakes being made.
In the poka-yoke technique, employees overcome disabilities and human errors during the manufacturing process.
