You are probably aware of our Lean Six Sigma Masterclass – designed to get you a Lean Six Sigma Green Belt Certificate – but what about if you need to develop NEW processes, products, and services?
Well, luckily Projex Academy has a Masterclass that teaches you how to master Design For Six Sigma (DfSS) using the DMADV Method.
These video modules are a companion Masterclass to our Projex Academy Lean Six Sigma Masterclass:
- Module 1 DMAIC AND DMADV
- Module 2 DMADV DEFINE AND ANALYZE PHASES
- Module 3 DMADV DESIGN AND VERIFY PHASES
- Module 4 THE HOUSE OF QUALITY (QFD) Part ONE
- Module 5 THE HOUSE OF QUALITY (QFD) Part TWO
- Module 6 QFD AND THE PUGH MATRIX
Lean Six Sigma used the DMAIC Method, whereas DfSS uses the DMADV Method – Define, Measure, Analyse, Design, and Verify
DMAIC is used to improve existing processes, but sometimes the process does not exist and you need to create one, or perhaps for new services or products
It may be that your current process is so poor that scrapping it and starting again makes more sense!
DMADV will help introduce new products and services quickly and to a consistently high standard
When redesigning a process we focus on the customer, when designing a new service or product there may not be a customer yet, so we focus on the demands of the (potential) marketplace
Where the customer is involved, this means both end-user customers and internal business stakeholders and users
Customer requirements and the resulting Critical To Quality (CTQ) requirements are established early on and the DMADV framework ensures that these requirements are satisfied in the final product, service, or process
As with DMAIC, we managed by facts and not speculation to ensure that new designs reflect customer CTQs and provide real value to the customers.
DMADV projects are more resource-hungry than DMAIC projects in terms of people, IT involvement, and cost
Despite these higher costs and risks, DMADV projects bring higher rewards
In large organizations using Lean Six Sigma, 20 DMAIC projects will likely be carried out for every DMADV project
There are likely to be many lean projects, a moderate number of DMAIC projects, and a few DfSS projects as the organization gradually reduces rework and waste, improving process flow and reducing cycle times.
Understanding Design for Six Sigma (DFSS)
Design for Six Sigma (DFSS) is a systematic approach to designing products and processes that meet customer expectations and achieve high levels of quality. Unlike traditional Six Sigma, which focuses on improving existing processes, DFSS is used to create new processes or products from the ground up. The goal is to design it right the first time, minimizing defects and variations.
The DFSS Methodology
Define
The first step in DFSS is to define the project goals and customer requirements. This involves understanding what the customer needs and expects from the product or process. Tools like Voice of the Customer (VoC) and Quality Function Deployment (QFD) are often used to gather and prioritize customer requirements.
Measure
In the measure phase, the team collects data to establish baseline performance and identify critical to quality (CTQ) characteristics. These are the key attributes that must be met to satisfy customer requirements. Measurement systems analysis (MSA) is used to ensure that the data collected is accurate and reliable.
Analyze
During the analyze phase, the team uses statistical tools to identify potential design concepts and evaluate their feasibility. Techniques like Failure Modes and Effects Analysis (FMEA) and Design of Experiments (DOE) help identify potential risks and optimize design parameters.
Design
In the design phase, the team develops detailed designs for the product or process. This includes creating prototypes, conducting simulations, and performing pilot tests. The goal is to refine the design to meet all CTQ characteristics and ensure it can be produced consistently.
Verify
The final phase is to verify that the design meets customer requirements and performs as expected. This involves rigorous testing and validation to ensure that the product or process is ready for full-scale production. Once verified, the design is documented and handed over to production.
How DFSS is Applied in an Organization
Product Development
DFSS is widely used in product development to ensure that new products meet customer needs and achieve high levels of quality. For example, an automotive company might use DFSS to design a new car model. By involving customers early in the design process and using statistical tools to optimize design parameters, the company can create a car that meets customer expectations and performs reliably.
Process Design
In addition to product development, DFSS is also used to design new processes. For instance, a manufacturing company might use DFSS to design a new assembly line. By analyzing potential risks and optimizing process parameters, the company can create an efficient and reliable assembly line that produces high-quality products.
Service Design
DFSS is not limited to manufacturing; it can also be applied to service design. For example, a healthcare organization might use DFSS to design a new patient care process. By understanding patient needs and optimizing process steps, the organization can create a care process that improves patient outcomes and satisfaction.
Software Development
In software development, DFSS can be used to design new software applications. By involving users early in the design process and using statistical tools to optimize software performance, developers can create applications that meet user needs and perform reliably.
Benefits of DFSS
Improved Quality
One of the primary benefits of DFSS is improved quality. By designing products and processes to meet customer requirements from the start, organizations can reduce defects and variations, leading to higher quality outcomes.
Cost Savings
DFSS helps organizations avoid costly rework and redesigns by getting the design right the first time. This leads to significant cost savings in the long run.
Customer Satisfaction
By focusing on customer requirements and involving customers early in the design process, DFSS helps organizations create products and processes that meet or exceed customer expectations, leading to higher customer satisfaction.
Reduced Time to Market
DFSS streamlines the design process by using statistical tools to optimize design parameters and identify potential risks early. This helps organizations bring new products and processes to market faster.
Enhanced Innovation
DFSS encourages a systematic approach to design, fostering creativity and innovation. By involving cross-functional teams and using data-driven decision-making, organizations can develop innovative solutions that meet customer needs.
Real-World Examples
Automotive Industry
In the automotive industry, DFSS is used to design new car models and manufacturing processes. For example, a car manufacturer might use DFSS to design a new engine. By involving customers in the design process and using statistical tools to optimize engine performance, the manufacturer can create an engine that meets customer expectations and performs reliably.
Healthcare
In healthcare, DFSS is used to design new patient care processes and medical devices. For example, a hospital might use DFSS to design a new patient admission process. By understanding patient needs and optimizing process steps, the hospital can create a process that improves patient outcomes and satisfaction.
Consumer Electronics
In the consumer electronics industry, DFSS is used to design new gadgets and devices. For example, a smartphone manufacturer might use DFSS to design a new phone model. By involving users in the design process and using statistical tools to optimize phone performance, the manufacturer can create a phone that meets user needs and performs reliably.
Financial Services
In financial services, DFSS is used to design new financial products and services. For example, a bank might use DFSS to design a new loan application process. By understanding customer needs and optimizing process steps, the bank can create a process that improves customer satisfaction and reduces processing time.
Conclusion
Design for Six Sigma (DFSS) is a powerful methodology for designing products and processes that meet customer requirements and achieve high levels of quality.
By following a systematic approach and using statistical tools, organizations can create innovative solutions that improve quality, reduce costs, and enhance customer satisfaction.
Whether in manufacturing, healthcare, software development, or financial services, DFSS provides a framework for designing it right the first time and achieving excellence in every aspect of the business.
