Healthcare organizations worldwide are constantly seeking ways to enhance patient care quality while reducing costs and inefficiencies. One methodology that has proven remarkably effective in achieving these goals is Lean Six Sigma, a data-driven approach to process improvement that originated in manufacturing but has found powerful applications in healthcare settings. At the heart of any successful Six Sigma project lies the Define phase, a critical first step that establishes the foundation for all subsequent improvement efforts.
Understanding how to properly execute the Define phase can mean the difference between a successful patient care improvement initiative and one that fails to deliver meaningful results. This article explores the Define phase in detail, examining its components, importance, and practical application in healthcare environments.

Understanding Six Sigma in Healthcare Context
Before diving into the Define phase specifically, it is essential to understand what lean six sigma represents in healthcare. Six Sigma is a disciplined, statistical-based methodology that aims to reduce variation and eliminate defects in any process. When we talk about “defects” in healthcare, we refer to medication errors, patient falls, hospital-acquired infections, billing mistakes, and any other occurrence that negatively impacts patient outcomes or organizational efficiency.

The methodology follows a structured approach known as DMAIC, which stands for Define, Measure, Analyze, Improve, and Control. Each phase builds upon the previous one, creating a comprehensive framework for sustainable improvement. The Define phase, as the initial step, sets the trajectory for the entire project.

What is the Define Phase?
The Define phase represents the crucial starting point where healthcare teams clearly articulate the problem they intend to solve, establish project boundaries, and align stakeholders around common objectives. This phase answers fundamental questions: What problem are we solving? Why does it matter? Who is affected? What are the boundaries of our improvement effort?
In healthcare settings, the Define phase takes on particular importance because of the complex nature of medical processes and the high stakes involved. A poorly defined project can waste valuable resources, frustrate staff, and ultimately fail to improve patient outcomes. Conversely, a well-executed Define phase creates clarity, builds team cohesion, and establishes metrics for success.
Key Components of the Define Phase
Problem Statement Development
The cornerstone of the Define phase is crafting a clear, concise problem statement. In healthcare, this statement should describe the specific issue affecting patient care or organizational performance. For example, rather than stating “Emergency department wait times are too long,” a properly defined problem would read: “Patients experiencing non-life-threatening conditions in our emergency department wait an average of 4.5 hours before seeing a physician, exceeding our target of 2 hours and leading to patient dissatisfaction and potential clinical complications.”
A strong problem statement includes quantifiable metrics, specifies the gap between current and desired performance, and hints at the impact of the problem without jumping to solutions.
Project Charter Creation
The project charter serves as the official document that authorizes the improvement project and provides the team with clear direction. This document typically includes:
- Business case explaining why the project matters to the organization
- Problem and goal statements with specific, measurable objectives
- Project scope defining what is and is not included in the improvement effort
- Team members and their roles
- Timeline and milestones
- Resources required
- Expected benefits and return on investment
In healthcare environments, the project charter must also consider regulatory requirements, patient safety implications, and alignment with organizational strategic priorities.
Voice of the Customer (VOC) Analysis
Healthcare improvement projects must recognize phase requirements by incorporating the perspectives of those most affected by the problem. In medical settings, “customers” include patients, their families, referring physicians, nursing staff, and other stakeholders. Gathering VOC data through surveys, interviews, focus groups, and observation helps teams understand what matters most to these groups.
For instance, a project aimed at improving surgical scheduling might discover through VOC analysis that patients value clear pre-operative instructions and minimal cancellations, while surgeons prioritize efficient operating room turnover and equipment availability. This information shapes project goals and success metrics.
Stakeholder Analysis and Engagement
Healthcare delivery involves numerous interconnected departments and professional groups. The Define phase must identify all stakeholders who will be affected by or can influence the improvement project. Creating a stakeholder map helps teams recognize phase relationships and power dynamics that could impact project success.
Effective stakeholder engagement during the Define phase builds buy-in, uncovers potential obstacles, and leverages diverse expertise. For a project addressing medication administration errors, stakeholders would include physicians, nurses, pharmacists, information technology staff, and quality management personnel.
SIPOC Diagram: Mapping the Process
Another essential tool used during the Define phase is the SIPOC diagram, which stands for Suppliers, Inputs, Process, Outputs, and Customers. This high-level process map provides a visual representation of the workflow related to the problem.
For example, a SIPOC diagram for a patient discharge process might identify suppliers (physicians, case managers, pharmacy), inputs (discharge orders, medication reconciliation, patient education materials), process steps (order entry, medication preparation, patient teaching, transportation arrangement), outputs (discharged patient, follow-up appointments, prescriptions), and customers (patient, family, primary care physician, home health agency).
Creating a SIPOC diagram during the Define phase helps teams establish project boundaries and ensures everyone shares a common understanding of the process being improved.
Establishing Metrics and Goals
The Define phase concludes with establishing clear, measurable goals that align with organizational objectives. In lean six sigma projects, goals should be SMART: Specific, Measurable, Achievable, Relevant, and Time-bound.
Healthcare metrics might include clinical outcomes (infection rates, readmission rates, mortality rates), operational efficiency measures (length of stay, wait times, throughput), financial indicators (cost per case, revenue cycle metrics), or patient experience scores (satisfaction ratings, likelihood to recommend).
Setting baseline metrics during the Define phase provides the benchmark against which improvement will be measured in later phases.
Common Pitfalls to Avoid
Healthcare teams new to lean six sigma often encounter several challenges during the Define phase:
- Scope creep: Attempting to solve too many problems simultaneously dilutes focus and resources. Successful projects maintain clear boundaries.
- Solution jumping: The Define phase should characterize the problem, not prescribe solutions. Premature solution identification bypasses critical analysis.
- Vague objectives: Goals like “improve patient satisfaction” lack the specificity needed to drive action and measure success.
- Insufficient stakeholder engagement: Failing to involve key personnel early can lead to resistance and implementation challenges later.
- Data absence: Basing the problem statement on anecdotes rather than data undermines the scientific foundation of Six Sigma.
Real-World Healthcare Application
Consider a hospital aiming to reduce central line-associated bloodstream infections (CLASBIs). During the Define phase, the team would gather data showing current infection rates, calculate the clinical and financial impact of these infections, identify affected units and patient populations, engage stakeholders including infection prevention specialists and bedside nurses, establish a goal such as “reduce CLABSI rates by 50% within six months,” and create a project charter authorizing the improvement effort.
This thorough Define phase work ensures the team has clarity about the problem, stakeholder support, measurable objectives, and organizational authorization before proceeding to measure and analyze root causes.
Conclusion
The Define phase represents the critical foundation of any successful healthcare improvement project using lean six sigma methodology. By investing time and effort to clearly articulate problems, engage stakeholders, establish boundaries, and set measurable goals, healthcare organizations position their improvement teams for success. When teams recognize phase requirements and follow the structured Define approach, they create alignment, build momentum, and establish the data-driven foundation necessary for sustainable patient care improvements. Whether addressing clinical quality, operational efficiency, or patient experience, a well-executed Define phase dramatically increases the likelihood of achieving meaningful, lasting results that benefit patients, staff, and the organization as a whole.
