In the world of process improvement and organizational excellence, understanding the intricate relationship between problems and goals forms the cornerstone of successful project execution. The Define phase of the DMAIC (Define, Measure, Analyze, Improve, Control) methodology serves as the critical foundation where this relationship takes shape, setting the trajectory for all subsequent improvement efforts.
The Foundation of Process Improvement: The Define Phase
The Define phase represents the first and arguably most crucial step in the Lean Six Sigma methodology. This initial stage demands careful attention to articulating the problem statement while simultaneously establishing clear, measurable goals. Without proper definition, even the most sophisticated improvement efforts can drift off course, consuming resources without delivering meaningful results.

Organizations often struggle with the fundamental challenge of distinguishing between symptoms and root causes. A manufacturing facility might report that “production delays are causing customer dissatisfaction,” but this statement merely scratches the surface. The Define phase requires practitioners to dig deeper, transforming vague concerns into precise problem statements that naturally connect to achievable goals.

Establishing the Problem Statement
A well-crafted problem statement serves as the compass for your improvement project. It must be specific, observable, and measurable. Consider the difference between these two approaches:
Weak Problem Statement: Our customer service is poor and needs improvement.
Strong Problem Statement: Between January and March 2024, our customer service department experienced an average response time of 4.5 hours for email inquiries, exceeding our target of 2 hours by 125%, resulting in a 15% decrease in customer satisfaction scores from 85% to 70%.
The latter statement provides concrete data points, timeframes, and measurable impacts. This specificity enables teams to understand exactly what requires attention and establishes a baseline for measuring success.
Connecting Problems to Goals: The Critical Link
Once the problem is clearly defined, the next step involves establishing goals that directly address the identified issues. This connection must be logical, measurable, and achievable. Goals should follow the SMART criteria: Specific, Measurable, Achievable, Relevant, and Time-bound.
Using our customer service example, an appropriate goal would be: “Reduce average email response time from 4.5 hours to 2 hours or less within six months, thereby improving customer satisfaction scores from 70% back to 85% or higher.”
This goal directly responds to the problem statement, provides clear metrics for success, and establishes a realistic timeframe for achievement.
Real World Application: A Manufacturing Case Study
Consider a mid-sized electronics manufacturing company experiencing quality issues. The initial complaint from management was simply “too many defects.” Through proper Define phase methodology, the team developed the following comprehensive problem statement:
“During the second quarter of 2024, production Line B at our Dallas facility produced 2,400 defective circuit boards out of 30,000 total units (8% defect rate), compared to the company standard of 1.5% and industry benchmark of 2%. This resulted in $180,000 in rework costs, delayed shipment of 15 customer orders, and contributed to a 12% decrease in on-time delivery performance.”
The corresponding goal statement became: “Reduce defect rate on production Line B from 8% to 2% or below within four months, eliminating $135,000 in quarterly rework costs and improving on-time delivery to 95% or higher.”
This example demonstrates how specific data points transform abstract concerns into actionable improvement targets. The team collected baseline data including defect counts, cost per defect, production volume, and delivery metrics. This information provided both the problem context and the foundation for measuring progress.
Data Collection in the Define Phase
Supporting data strengthens both problem statements and goal setting. In our manufacturing example, the team gathered the following baseline metrics:
- Total production volume: 30,000 units
- Defective units: 2,400 (8% defect rate)
- Average rework cost per unit: $75
- Total rework costs: $180,000
- On-time delivery rate: 83%
- Customer complaints: 23 formal complaints
- Production line efficiency: 72%
This quantitative foundation enabled the team to establish meaningful targets and track progress throughout the improvement project.
The Voice of the Customer: Aligning Problems and Goals with Stakeholder Needs
The Define phase must also incorporate the Voice of the Customer (VOC), ensuring that problems and goals align with stakeholder expectations. This involves gathering input from multiple sources including customers, employees, management, and other affected parties.
For a healthcare organization addressing patient wait times, the Define phase would include surveying patients about their experiences, interviewing staff about bottlenecks, reviewing appointment scheduling data, and consulting with physicians about workflow challenges. This comprehensive approach ensures that the defined problem reflects actual pain points rather than assumed issues.
Creating the Project Charter: Formalizing the Problem-Goal Relationship
The Project Charter serves as the formal document that captures the problem statement, goals, scope, and stakeholder information. This living document provides several critical functions:
- Establishes clear boundaries for the project scope
- Identifies team members and their roles
- Documents the business case and expected benefits
- Secures leadership commitment and resources
- Provides a reference point throughout the project lifecycle
The charter transforms the problem-goal relationship from conceptual understanding into operational reality, ensuring all stakeholders share a common vision of success.
Common Pitfalls in the Define Phase
Many improvement projects stumble due to inadequate attention during the Define phase. Common mistakes include:
Scope Creep: Attempting to solve too many problems simultaneously dilutes focus and resources. A manufacturing team might be tempted to address defects, delivery times, and employee training all at once, but this approach typically yields poor results. The Define phase should establish clear boundaries.
Vague Metrics: Goals like “improve customer satisfaction” or “reduce costs” lack the specificity needed for effective measurement. Every goal must include concrete numbers and timeframes.
Ignoring Stakeholder Input: Improvement efforts that neglect the Voice of the Customer or Voice of the Employee often solve the wrong problems. A technology company that defines the problem based solely on management perspective might miss critical user experience issues.
Insufficient Data: Making assumptions without supporting evidence leads to misdiagnosed problems. The Define phase requires actual data collection, even if preliminary, to validate that the perceived problem truly exists at the stated magnitude.
Moving Forward: From Define to Measure
A well-executed Define phase creates momentum for subsequent DMAIC phases. When the problem is clearly articulated and goals are precisely stated, the Measure phase can focus on collecting relevant data, the Analyze phase can identify root causes efficiently, and the Improve and Control phases can implement and sustain targeted solutions.
The relationship between problems and goals is not static. As projects progress, teams may need to refine their understanding, but the foundational work in the Define phase provides the flexibility to make informed adjustments while maintaining project focus.
