In the world of process improvement and quality management, establishing a clear starting point is crucial for measuring success. The Define Phase, the first step in the DMAIC (Define, Measure, Analyze, Improve, Control) methodology, serves as the foundation for any successful Lean Six Sigma project. This critical phase involves setting baseline performance expectations that will guide your improvement efforts and provide a benchmark against which all future progress will be measured.
Understanding the Define Phase
The Define Phase represents the crucial first step in any structured process improvement initiative. During this phase, organizations establish the scope of their project, identify the problem they aim to solve, and most importantly, set baseline performance expectations. Without a clearly defined baseline, it becomes virtually impossible to measure improvement or demonstrate the value of your efforts to stakeholders.

Think of baseline performance expectations as your project’s starting line. Just as a runner needs to know their current pace before attempting to improve their speed, businesses must understand their current performance levels before implementing changes. This baseline serves multiple purposes: it validates that a problem exists, quantifies the gap between current and desired performance, and provides concrete data for justifying the resources invested in improvement efforts.

Key Components of Baseline Performance Expectations
Current State Assessment
Before setting any expectations, you must thoroughly understand your current state. This involves collecting data on existing processes, identifying pain points, and documenting how work currently flows through your organization. A comprehensive current state assessment includes both quantitative metrics and qualitative observations from team members who interact with the process daily.
For example, consider a customer service department experiencing high call volumes and customer complaints. The current state assessment might reveal that the average call handling time is 12 minutes, customer satisfaction scores average 6.5 out of 10, and first call resolution rates sit at 68%. These numbers establish your baseline performance metrics.
Defining Critical Metrics
Not all metrics carry equal weight in your improvement journey. During the Define Phase, you must identify which key performance indicators (KPIs) truly matter for your project. These should align with both customer requirements and business objectives. Common categories of metrics include quality measures, time-based metrics, cost factors, and customer satisfaction indicators.
In our customer service example, critical metrics might include average handling time, first call resolution rate, customer satisfaction score, cost per call, and employee utilization rate. Each metric provides a different perspective on performance and together they paint a complete picture of the process health.
Practical Steps for Setting Baseline Performance Expectations
Step 1: Define the Project Scope
Clear boundaries prevent scope creep and ensure focused improvement efforts. Document what is included in your project and, equally important, what falls outside its boundaries. A well-defined scope statement might read: “This project will focus on improving the first call resolution rate for technical support inquiries received by the IT helpdesk during business hours, excluding after-hours emergency calls and password reset requests.”
Step 2: Identify Stakeholders and Requirements
Every process improvement project affects multiple stakeholders, from customers to employees to senior leadership. Understanding their requirements and expectations helps establish meaningful baseline metrics. Create a stakeholder analysis that identifies who will be impacted, what they care about, and how success will be measured from their perspective.
Step 3: Collect Baseline Data
Data collection should be systematic and representative of typical operating conditions. Gather enough data to account for natural variation in your process. A single day’s performance might not reflect true baseline conditions due to unusual circumstances. Industry best practice suggests collecting at least 30 data points to establish a reliable baseline.
Let us examine a realistic example from a manufacturing environment. A production line making automotive components collected the following data over four weeks:
Sample Baseline Data Set:
- Total units produced: 45,600 units
- Defective units: 2,280 units
- Defect rate: 5.0%
- Average production time per unit: 8.5 minutes
- Machine downtime: 14.2 hours per week
- Rework costs: $18,400
- Customer returns: 156 units (0.34%)
This data establishes a clear baseline showing where the process currently stands. The 5.0% defect rate becomes the benchmark against which improvement efforts will be measured.
Step 4: Calculate Process Capability
Understanding how capable your process is of meeting specifications provides valuable context for baseline expectations. Process capability indices like Cp and Cpk quantify how well your process performs relative to customer requirements. A Cpk value below 1.33 typically indicates significant room for improvement, while values above 1.67 suggest a highly capable process.
In our manufacturing example, if the customer specification allows for a maximum 2.0% defect rate, and the current baseline shows 5.0%, the process is clearly not meeting customer requirements. This gap between current performance and customer expectations justifies the improvement project and helps prioritize resources.
Common Challenges in Setting Baseline Expectations
Insufficient or Unreliable Data
Many organizations discover during the Define Phase that they lack adequate data on their current performance. Historical data may be incomplete, inconsistent, or simply nonexistent. When faced with this challenge, you may need to implement temporary data collection systems before proceeding with your improvement project. While this delays the project, attempting to improve a process without understanding its current state often leads to wasted effort and questionable results.
Resistance to Transparency
Establishing baseline metrics sometimes meets resistance from team members who worry about being judged or held accountable for poor performance. Effective communication about the purpose of baseline measurement helps overcome this obstacle. Emphasize that baseline data reflects the process, not the people, and that the goal is improvement, not blame.
Selecting the Wrong Metrics
Organizations sometimes focus on metrics that are easy to measure rather than those that truly matter. Vanity metrics that look impressive but do not drive meaningful improvement waste valuable resources. Always tie your baseline metrics back to customer requirements and business objectives to ensure relevance.
Documenting Your Baseline
Proper documentation ensures that everyone involved in the project understands the starting point and can reference it throughout the improvement journey. A comprehensive baseline document should include the data collection methodology, sample sizes, time periods covered, any unusual circumstances that might affect the data, and clear definitions of each metric measured.
Create visual representations of your baseline data whenever possible. Control charts, histograms, and process maps help stakeholders quickly grasp current performance levels. In our customer service example, a run chart showing daily call handling times over the baseline period might reveal patterns or trends that influence your improvement approach.
Linking Baseline to Project Goals
The baseline performance data directly informs your project goals. Goals should be specific, measurable, achievable, relevant, and time-bound (SMART). If your baseline defect rate is 5.0%, a goal might be to “reduce the defect rate to 2.0% or below within six months.” This goal is specific (defect rate), measurable (2.0%), achievable (based on industry benchmarks), relevant (meets customer requirements), and time-bound (six months).
The gap between baseline and goal also helps estimate the potential financial impact of your project. If each defect costs $8.06 in rework (based on the $18,400 rework cost divided by 2,280 defects), reducing defects from 5.0% to 2.0% would save approximately $6,890 monthly, or $82,680 annually. These projections justify the project investment and help secure leadership support.
Building a Foundation for Success
Setting baseline performance expectations during the Define Phase creates a solid foundation for your entire improvement project. It provides the evidence needed to justify the project, the metrics required to track progress, and the reference point for celebrating success. Without this foundation, improvement efforts lack direction and credibility.
Organizations that invest time in thoroughly defining their baseline position themselves for sustainable improvement. They can confidently move forward through the remaining DMAIC phases knowing exactly where they started and where they aim to go. This clarity transforms abstract improvement goals into concrete, measurable objectives that motivate teams and demonstrate value to stakeholders.
