DMADV stands for Define, Measure, Analyze, Design, and Verify – a structured methodology that guides organizations through the systematic creation of new processes or complete redesign of existing ones. Unlike reactive improvement approaches, DMADV takes a forward-thinking stance, ensuring quality and efficiency are built into every aspect of the design from the very beginning.
The DMADV methodology emerged as part of the broader Six Sigma initiative, specifically addressing the need for a systematic approach to new product and process development. This methodology recognizes that prevention is more cost-effective than correction, making it an invaluable tool for organizations seeking sustainable competitive advantages.
Furthermore, Six Sigma DMADV integrates statistical analysis, customer voice, and design thinking to create solutions that consistently meet or exceed performance expectations. The methodology’s strength lies in its data-driven approach, which eliminates guesswork and ensures decisions are based on empirical evidence rather than assumptions.

What is DMADV?
So, what does DMADV stand for? It’s an acronym for Define, Measure, Analyze, Design, Verify—a five-step methodology within Six Sigma designed to create new processes or products or overhaul ones that are too broken to fix with incremental tweaks. Unlike its cousin, the DMAIC process (Define, Measure, Analyze, Improve, Control), which refines existing systems, DMADV is all about starting fresh with a focus on quality and customer satisfaction.
Think of DMADV as a GPS for innovation. It guides you from understanding customer needs to delivering a solution that’s virtually defect-free. Whether you’re launching a new product or redesigning a supply chain, DMADV ensures every step aligns with Lean Six Sigma principles, minimizing waste and maximizing value.
DMADV vs. DMAIC: What’s the Difference?
You might be asking, what’s the difference between DMAIC and DMADV? Both are Lean Six Sigma methodologies, but they serve different purposes:
- DMAIC (Six Sigma DMAIC) improves existing processes. It’s like renovating a house to make it more functional.
- DMADV (Six Sigma DMADV) designs new processes or products from the ground up. It’s like building a brand-new home tailored to the owner’s needs.
For example, if your customer support process is slow, DMAIC might streamline it. But if you’re creating a new support system for a product that doesn’t yet exist, DMADV is your go-to. The differences between the DMAIC and DMADV processes include their focus: DMAIC reacts to problems, while DMADV proactively prevents them.

Five Phases of DMADV
Let’s break down the DMADV methodology into its five phases, each a critical step in crafting a flawless process or product:
1. Define: Set the Foundation
The Define phase is like drawing the blueprint for your project. Here, you identify the project’s purpose, scope, and customer requirements. You ask, “What do our customers need, and how will we measure success?” Tools like the Project Charter, Voice of the Customer (VOC) surveys, and Stakeholder Analysis help you align goals with customer expectations and business objectives.
For instance, a company designing a new app might use VOC to gather user feedback, ensuring the app’s features meet real-world needs. A clear definition sets the stage for success, ensuring every step stays customer-focused.
2. Measure: Quantify Customer Needs
Next, the Measure phase translates customer needs into measurable Critical to Quality (CTQ) characteristics. Think of CTQs as the must-haves that define quality—like fast load times for an app or quick turnaround for a service. You collect data to establish baselines, using tools like Data Collection Plans, Statistical Sampling, and Process Capability Analysis.
For example, a manufacturer creating a new product might measure tolerances to ensure components meet strict quality standards. This phase ensures you have clear, data-driven metrics to guide the design process.
3. Analyze: Explore Design Options
In the Analyze phase, you dive into the data to identify the best design options. You develop alternatives, evaluate them, and select the one that best meets CTQs within constraints like cost or time. Tools like Quality Function Deployment (QFD), Pugh Matrix, and Failure Modes and Effects Analysis (FMEA) help you weigh options and anticipate risks.
Imagine a retailer designing a new checkout process. They might analyze multiple layouts to find one that minimizes wait times while staying cost-effective. This phase is about making informed, data-driven choices.
4. Design: Build the Solution
Now it’s time to create. The Design phase involves crafting a detailed plan for the chosen solution, often starting with a high-level design and refining it into specifics. You build prototypes, run simulations, and test for errors using tools like Design of Experiments (DOE) and Monte Carlo Simulation.
For example, a healthcare provider designing a new patient intake system might create a prototype, test it in a pilot program, and tweak it based on feedback. This phase ensures the design is robust and ready for real-world use.
5. Verify: Ensure Success
The Verify phase (sometimes called Validate) confirms the design meets customer and business needs. You run trials, pilot the process, and gather feedback to ensure quality. Tools like Control Charts and Pilot Testing help validate performance.
For instance, a tech company launching a new software feature might roll it out to a small user group, monitor performance, and make final adjustments before full release. This phase guarantees the solution is ready for prime time.
Why DMADV Matters for Businesses?
Why should you care about Six Sigma DMADV? Because it’s a game-changer for operational excellence. Here’s why:
- Customer-Centric Design: DMADV prioritizes the Voice of the Customer, ensuring products or processes meet real needs.
- Defect Prevention: By designing quality in from the start, DMADV reduces costly rework. Six Sigma aims for fewer than 3.4 defects per million opportunities.
- Cost Savings: A well-designed process minimizes waste, saving time and money.
