In the world of process improvement and innovation, organizations constantly seek methodologies that can guide them from concept to successful implementation. The DMEDI framework (Define, Measure, Explore, Develop, Implement) stands out as a structured approach specifically designed for creating new processes, products, or services. Unlike its cousin DMAIC which focuses on improving existing processes, DMEDI provides a roadmap for innovation and new development initiatives.
This comprehensive guide will walk you through each phase of the DMEDI methodology, complete with practical examples and actionable steps you can apply in your organization. You might also enjoy reading about How to Master Mixture Designs: A Comprehensive Guide to Optimizing Product Formulations.
Understanding the DMEDI Framework
DMEDI is a five-phase approach rooted in Lean Six Sigma principles. It provides a systematic method for designing and implementing new processes while minimizing defects and maximizing efficiency from the outset. This framework is particularly valuable when your organization needs to develop something entirely new rather than fix what already exists.

The five phases work sequentially, with each stage building upon the insights and deliverables of the previous one. Let us explore each phase in detail.
Phase 1: Define
The Define phase establishes the foundation for your entire project. During this critical first stage, you must clearly articulate what you intend to create and why it matters to your organization and customers.
Key Activities in the Define Phase
Identify Customer Requirements: Begin by conducting thorough research into customer needs and expectations. For example, if you are developing a new customer service process for a telecommunications company, you might survey 500 customers to understand their pain points with current service delivery.
Create a Project Charter: Document the project scope, objectives, timeline, and team members. Your charter should answer fundamental questions about what success looks like and what resources you will need.
Define Critical-to-Quality (CTQ) Metrics: Establish measurable characteristics that directly relate to customer satisfaction. In our telecommunications example, CTQ metrics might include call resolution time (target: under 5 minutes), first-call resolution rate (target: 85%), and customer satisfaction score (target: 4.5 out of 5).
Sample Define Phase Output
Consider a manufacturing company developing a new quality inspection process. Their Define phase might yield these specifications:
- Project Goal: Create an automated inspection system that reduces defect rates by 40%
- Timeline: 6 months from initiation to full implementation
- Primary Stakeholders: Quality assurance team, production managers, IT department
- Budget Allocation: $150,000
- Success Criteria: Defect detection rate above 95%, inspection time reduced by 50%
Phase 2: Measure
The Measure phase involves quantifying current capabilities and establishing baseline metrics. This phase answers the question: where are we starting from, and what does good performance look like?
Key Activities in the Measure Phase
Benchmark Industry Standards: Research what competitors and industry leaders achieve in similar processes. This provides context for setting realistic yet ambitious targets.
Assess Current Capabilities: Evaluate your organization’s existing resources, skills, and infrastructure. What can you leverage from current operations?
Establish Measurement Systems: Determine how you will collect and analyze data throughout the project. Ensure your measurement methods are reliable and consistent.
Sample Measurement Data
Returning to our telecommunications customer service example, the Measure phase might produce this baseline data:
- Current average call resolution time: 12 minutes
- Current first-call resolution rate: 62%
- Current customer satisfaction score: 3.2 out of 5
- Available customer service representatives: 45
- Peak call volume hours: 9 AM to 11 AM, 2 PM to 4 PM
- Most common call types: billing inquiries (35%), technical support (40%), account changes (25%)
This data provides concrete starting points and helps identify specific areas requiring the most attention in subsequent phases.
Phase 3: Explore
The Explore phase is where creativity meets analysis. Here, you generate multiple potential solutions and evaluate them systematically to identify the most promising approach.
Key Activities in the Explore Phase
Brainstorm Alternative Solutions: Encourage diverse thinking from your team. Do not limit ideas prematurely. For our customer service example, alternatives might include implementing AI chatbots, creating specialized service tiers, developing comprehensive knowledge bases, or redesigning call routing systems.
Conduct Feasibility Analysis: Evaluate each option against criteria such as cost, implementation time, technical requirements, and expected impact. Create a scoring matrix to compare options objectively.
Perform Risk Assessment: Identify potential obstacles and mitigation strategies for top solutions. What could go wrong, and how will you address these challenges?
Sample Exploration Matrix
Your team might evaluate four potential solutions using this scoring system (scale 1 to 10):
Solution A (AI Chatbot Integration): Cost-effectiveness: 7, Implementation Speed: 6, Expected Impact: 8, Technical Feasibility: 7, Total Score: 28
Solution B (Specialized Service Tiers): Cost-effectiveness: 9, Implementation Speed: 8, Expected Impact: 6, Technical Feasibility: 9, Total Score: 32
Solution C (Enhanced Knowledge Base): Cost-effectiveness: 8, Implementation Speed: 7, Expected Impact: 7, Technical Feasibility: 8, Total Score: 30
Solution D (Redesigned Call Routing): Cost-effectiveness: 6, Implementation Speed: 5, Expected Impact: 9, Technical Feasibility: 6, Total Score: 26
Based on this analysis, Solution B (Specialized Service Tiers) emerges as the most balanced approach, though you might incorporate elements from other solutions.
Phase 4: Develop
During the Develop phase, you transform your chosen concept into a detailed, actionable plan. This phase involves creating prototypes, testing assumptions, and refining your approach based on pilot results.
Key Activities in the Develop Phase
Create Detailed Process Maps: Document every step of your new process, including decision points, handoffs, and quality checkpoints. Visualize the workflow from beginning to end.
Build and Test Prototypes: Develop a working model of your solution on a small scale. For the specialized service tiers, you might pilot the program with one product line or regional office.
Conduct Pilot Testing: Run controlled tests to validate your design assumptions. Collect data meticulously to compare against your target metrics.
Refine Based on Feedback: Use pilot results to make adjustments before full-scale rollout. Be prepared to iterate multiple times.
Sample Pilot Testing Results
After piloting the specialized service tier system for 30 days with 500 customers, you might observe:
- Average call resolution time decreased to 7 minutes (target: 5 minutes)
- First-call resolution rate increased to 78% (target: 85%)
- Customer satisfaction score improved to 4.1 out of 5 (target: 4.5)
- Employee satisfaction with new system: 8.2 out of 10
- Cost per call reduced by 23%
These results show significant progress toward targets while highlighting areas needing additional refinement before full implementation.
Phase 5: Implement
The final phase brings your new process or product to full operational status. Implementation requires careful planning, comprehensive training, and ongoing monitoring to ensure sustained success.
Key Activities in the Implement Phase
Develop Implementation Plan: Create a detailed timeline with specific milestones, responsibilities, and resource allocations. Consider a phased rollout rather than a sudden switch to minimize disruption.
Train All Stakeholders: Ensure everyone affected by the new process receives appropriate training. For our customer service example, this includes representatives, supervisors, IT support staff, and management.
Execute Rollout: Launch according to your plan while remaining flexible to address unexpected issues. Maintain open communication channels for feedback and problem reporting.
Monitor Performance: Track your CTQ metrics continuously. Compare actual results against targets and investigate any variances promptly.
Establish Control Mechanisms: Implement systems to maintain performance over time. This might include regular audits, ongoing training programs, and performance dashboards.
Sample Implementation Timeline
A structured rollout might look like this:
- Week 1-2: Train first wave of customer service representatives (15 people)
- Week 3-4: Launch specialized tiers for Product Category A
- Week 5-6: Train second wave (15 people) and evaluate initial results
- Week 7-8: Expand to Product Categories B and C
- Week 9-10: Train final wave (15 people) and launch remaining categories
- Week 11-12: Full operation across all categories with intensive monitoring
- Month 4-6: Ongoing optimization and refinement
Measuring DMEDI Success
Three months after full implementation, you should conduct a comprehensive review. Success indicators might include:
- Achievement of CTQ targets (call resolution time, first-call resolution rate, satisfaction scores)
- Return on investment calculations showing cost savings or revenue gains
- Employee adoption rates and satisfaction levels
- Customer feedback and retention metrics
- Process stability measurements showing consistent performance
Common Pitfalls to Avoid
Organizations implementing DMEDI often encounter these challenges:
Inadequate Define Phase: Rushing through initial planning leads to scope creep and misaligned objectives. Invest sufficient time in clearly articulating goals and requirements.
Insufficient Data Collection: Making decisions without adequate measurement leads to solutions based on assumptions rather than facts. Commit to rigorous data gathering throughout all phases.
Limited Stakeholder Involvement: Excluding key stakeholders results in resistance during implementation. Engage all affected parties from the beginning.
Skipping Pilot Testing: Attempting full-scale implementation without piloting risks costly failures. Always validate your design with controlled testing.
Neglecting Change Management: Focusing solely on technical aspects while ignoring human factors undermines adoption. Address cultural and behavioral dimensions alongside process design.
