In today’s competitive business environment, organizations constantly face obstacles that prevent them from achieving their objectives. Whether you’re managing a manufacturing process, implementing a healthcare protocol, or overseeing a service delivery system, identifying and removing barriers is crucial for success. Barrier analysis is a systematic method that helps professionals investigate why something did not happen as planned and determine what obstacles prevented the desired outcome.
This comprehensive guide will walk you through the barrier analysis process step by step, providing you with practical tools to enhance your problem-solving capabilities and drive meaningful improvements in your organization.

Understanding Barrier Analysis
Barrier analysis is a structured investigation technique used to identify the factors that prevented a desired behavior, action, or outcome from occurring. Originally developed for safety investigations, this methodology has expanded across various industries as an effective tool for root cause analysis and process improvement.

The fundamental principle behind barrier analysis is simple: when an undesired outcome occurs or a desired outcome fails to materialize, barriers have either failed to prevent the negative event or have prevented the positive event from occurring. By systematically identifying these barriers, organizations can develop targeted interventions that address the root causes rather than merely treating symptoms.
When to Use Barrier Analysis
Barrier analysis proves particularly valuable in several scenarios. Organizations should consider implementing this technique when investigating safety incidents, analyzing quality defects, examining process failures, understanding compliance issues, or exploring customer service breakdowns. The method works best when examining specific events rather than chronic problems, though it can be adapted for various situations.
The Seven Step Barrier Analysis Process
Step 1: Define the Target Event
The first step requires clearly defining the event you are investigating. This definition should be specific, measurable, and focused on a single incident or occurrence. Ambiguous event definitions lead to unfocused investigations and ineffective solutions.
For example, instead of defining your target event as “poor customer satisfaction,” you would specify “Customer order number 5821 was delivered three days late, resulting in a formal complaint on November 15th.” This precision allows for a thorough and targeted investigation.
Step 2: Describe the Desired Outcome
Articulate what should have happened if everything had proceeded according to plan. This step establishes your baseline for comparison and helps identify where the process deviated from expectations.
Using our previous example, the desired outcome would be: “Customer order number 5821 should have been processed within 24 hours, shipped within 48 hours, and delivered to the customer within two business days as per our standard service agreement.”
Step 3: Identify the Actual Outcome
Document precisely what actually occurred. Gather factual information without inserting opinions or assumptions. Interview witnesses, review documentation, examine physical evidence, and collect data that paints an accurate picture of events.
In our sample case, the investigation revealed: “Order 5821 was received on November 10th at 9:30 AM. The order remained in the processing queue for 36 hours due to inventory discrepancies. Once processed, shipping was delayed an additional 24 hours because the assigned carrier was at capacity. The order finally shipped on November 13th and arrived on November 18th, five days after the order placement.”
Step 4: Determine the Behavioral Control Factors
Identify the human behaviors, system processes, or physical mechanisms that should have prevented the negative outcome or enabled the positive outcome. These are your potential barriers. Consider factors across multiple dimensions: knowledge and skills, physical capability, resources and materials, environmental factors, motivation and consequences, and cultural norms.
For our shipping delay example, behavioral control factors might include:
- Inventory management system accuracy
- Staff training on inventory reconciliation procedures
- Shipping capacity planning protocols
- Backup carrier relationships
- Order priority classification system
- Customer communication procedures during delays
Step 5: Analyze Each Barrier
For each identified behavioral control factor, determine whether it was present and functioning adequately. This analysis reveals which barriers failed and why. Create a systematic table to organize your findings.
Consider this sample barrier analysis table:
Barrier: Inventory Management System Accuracy
Present: Yes
Functioning: No
Analysis: System showed 150 units available, but physical count revealed only 87 units. Discrepancy due to unreturned items from previous quality check not logged back into system.
Barrier: Backup Carrier Relationships
Present: No
Functioning: Not Applicable
Analysis: Company relies exclusively on single carrier. No alternative shipping arrangements exist for capacity overflows.
Barrier: Customer Communication During Delays
Present: Yes
Functioning: No
Analysis: Communication protocol exists but requires manual initiation. Staff member assumed automated notification would trigger but system only notifies for cancellations, not delays.
Step 6: Identify Root Causes
Based on your barrier analysis, determine the fundamental reasons why barriers failed or were absent. Root causes typically fall into categories such as inadequate procedures, insufficient training, poor communication, lack of resources, conflicting priorities, or systemic design flaws.
In our example, root causes include:
- Lack of real-time inventory synchronization between quality control and warehouse management systems
- Absence of redundancy in shipping partnerships
- Gap in staff understanding of automated versus manual notification triggers
- No early warning system for potential delivery delays
Step 7: Develop and Implement Solutions
Create targeted interventions that address the identified root causes. Effective solutions should be specific, measurable, achievable, relevant, and time-bound. Prioritize solutions based on their potential impact and implementation feasibility.
Sample solutions for our case study:
- Implement automated inventory synchronization between quality control and warehouse systems within 30 days
- Establish contracts with two backup carriers within 60 days
- Conduct training sessions on customer communication protocols with all customer service staff within two weeks
- Deploy predictive delay notification system that alerts customers when orders exceed normal processing times
Best Practices for Effective Barrier Analysis
Success with barrier analysis requires commitment to several key principles. First, maintain objectivity throughout your investigation. Focus on systems and processes rather than blaming individuals. People typically work within the constraints of the systems surrounding them.
Second, involve diverse perspectives in your analysis. Cross-functional teams bring varied insights that reveal barriers invisible to single-department investigations. Include frontline workers who directly interact with the processes being examined.
Third, document everything thoroughly. Detailed documentation ensures reproducibility, facilitates organizational learning, and provides evidence for improvement initiatives. Create templates that standardize your barrier analysis process.
Fourth, follow through with implementation. Even the most thorough analysis becomes worthless without action. Assign clear ownership for each corrective action, establish timelines, and monitor progress regularly.
Integrating Barrier Analysis with Quality Improvement Methodologies
Barrier analysis complements other quality improvement approaches exceptionally well. When integrated with Lean Six Sigma methodologies, barrier analysis provides a focused investigation tool within the broader DMAIC framework (Define, Measure, Analyze, Improve, Control). The technique fits naturally into the Analyze phase, helping teams identify specific obstacles preventing process optimization.
Organizations practicing Total Quality Management can use barrier analysis as part of their continuous improvement culture. The method aligns perfectly with the plan-do-check-act cycle, providing structured analysis during the check phase.
Measuring the Effectiveness of Your Barrier Analysis
To ensure your barrier analysis efforts deliver value, establish metrics that track improvement. Monitor recurrence rates of similar events, measure time to resolution for identified issues, assess implementation rates of recommended solutions, and calculate the return on investment for improvement initiatives.
Create dashboards that visualize trends over time. Are you identifying barriers earlier in your processes? Are your solutions preventing recurrence? These metrics demonstrate the value of your analytical efforts and guide continuous refinement of your approach.
