Digitalizing Lock Out, Tag Out (LOTO): Transforming Safety in Construction
Transforming high-stakes safety procedures through user-centered research
The Product: A digital transformation of the Lock Out, Tag Out (LOTO) process—a highly regulated safety procedure critical for de-energizing equipment during construction maintenance. This project tackled the inefficiencies of traditional paper-based LOTO, aiming to digitize the workflow without compromising safety or compliance.
My Role: Lead UX Researcher—spearheading all user research initiatives from understanding complex workflows to validating proposed solutions, ensuring the digital transformation was deeply rooted in user needs and operational realities.
Key Outcome: 30% increase in permit handling efficiency, improved compliance, enhanced user satisfaction, and an estimated $300K saved annually in fines, administrative costs, and avoided downtime.

Project Snapshot
The Challenge
Manual Process, High Stakes
The traditional paper-based LOTO system was fraught with inefficiencies, manual errors, and communication gaps. Complex documentation, labor-intensive coordination, and frequent "temporary lifts" for testing created bottlenecks and increased the risk of non-compliance and safety incidents.
Critical Pain Points:
Project Engineers spending excessive time on error correction
Potential financial losses from inefficiencies
Reduced focus on critical safety responsibilities
High risk of non-compliance with OSHA standards
The Solution
Digitalizing for Safety & Efficiency
Our solution digitalized the entire LOTO process to streamline authorization, improve record-keeping, and facilitate seamless communication.
Goals:
Enhance Safety & Compliance: Reduce manual errors and ensure adherence to OSHA 29 CFR 1910.147
Boost Operational Efficiency: Streamline workflows, reduce administrative burden, eliminate bottlenecks
Improve User Experience: Create an intuitive system that empowers LOTO specialists to focus on safety, not paperwork
Research Process
Discovery: Understanding the Existing Process
Methodology:
Desk Research: Reviewed existing Lockout/Tagout Programs and OSHA compliance standards (29 CFR 1910.147) to understand regulatory requirements and company policies
User Interviews (N=6): Conducted in-depth interviews with LOTO specialists to gather first-hand insights on current workflows, daily tasks, pain points, and challenges
Key Research Insights:
Complexity: LOTO procedure was far more intricate and multi-step than initially perceived
Manual Documentation: Paper forms were time-consuming, error-prone, and difficult to track/update
"Temporary Lift" Bottlenecks: Frequent temporary lifts required repetitive authorization, documentation, and notification steps, creating significant delays
Coordination Challenges: Delays in notifying personnel about LOTO status changes and ensuring clear client communication
Compliance Risk: Manual processes increased risk of non-compliance, fines, and safety incidents
Visualizing Complexity: Process Mapping
Methodology: Developed a detailed process map visualizing the LOTO user journey from order placement through invoice approval, explicitly highlighting manual handoffs, repetitive tasks, and communication points.
Insight: The map revealed a highly complex, multi-step workflow with frequent temporary lifts, permit revalidation, and client coordination—pinpointing specific areas ripe for digital optimization. This served as a crucial blueprint for the proposed solution's functionality.
Iteration & Impact
Implementing Research Insights
Based on critical feedback from usability testing, the digital prototype was iteratively refined, significantly improving the Temporary Lift workflow.
Key Improvements:
Reduced cognitive load through simplified navigation and terminology
Improved efficiency via automation and real-time validation
Enhanced clarity with visual cues and contextual help
Measurable Outcomes:
User Interviews: 6 conducted to define initial problems
Usability Tests: 5 completed in first round (with 3 more planned)
Efficiency Gain: 30% increase in permit handling efficiency
Cost Savings: Estimated $300K saved annually in fines, administrative costs, and avoided downtime
Blueprinting the Solution: Research-Informed Features
Methodology: Based on identified pain points and workflow complexities, I collaborated closely with stakeholders and the designer to define core features of the digital solution.
Key Design Principles:
Mobile-First Design: Essential for on-site LOTO specialists
Centralized Notifications: Streamline communication during dynamic events like temporary lifts
Offline Functionality: Critical for areas with limited connectivity on large construction sites
Proposed Features:
Digital Permits & Forms: Replace paper with easy-to-fill, trackable digital forms with templates
Streamlined Temporary Lift Workflow: Automated authorization, digital checklists, instant notifications
Real-Time Notifications: Automated alerts for key actions (permit approvals, status changes) via multiple channels
Centralized Documentation: Single source of truth for all LOTO-related records, improving searchability and audit readiness
Training Modules: Built-in resources to ensure user understanding and compliance tracking
Validation & Testing
Usability Testing with LOTO Specialists
Methodology: Recruited five LOTO specialists for first-round usability testing on a high-fidelity prototype. Observed how users interacted with digital flows, specifically around permit creation, temporary lifts, and navigation.
Uncovering Critical Pain Points
Quantitative Findings:
80% of users struggled with navigation and unclear button functionality
60% found field labels confusing or redundant
100% requested automation features to reduce manual effort
6 distinct pain points identified in the Temporary Lift form (cited as most frustrating workflow)
Qualitative Findings & Recommendations:
1. Confusing Navigation & Workflow
Problem: Users struggled to find forms (e.g., temporary lifts, E-Remove) and understand process steps
Recommendation: Implement clear, hierarchical menus, breadcrumb trails, progress indicators, and guided workflows for complex actions
User Quote: "There's a lot of info on here... I'm not sure what you would name it, but it'd be like a lot of overview of everything 'cause this content engine here is like showing everything." — User #3
2. Unclear Terminology & Field Labels
Problem: Jargon, inconsistent terms, and redundant fields caused confusion
Recommendation: Use simplified, consistent language, tooltips, examples, and conditional logic to reduce cognitive load
3. Lack of Automation & Data Validation
Problem: Users desired less manual effort and more error prevention
Recommendation: Implement auto-population, real-time validation, and automated notifications/approvals for key actions
User Quote: "If there's a way... instead of dragging and dropping the work authorization sheet, if there was a way to search for the work authorization number and then have that work authorization system automatically upload that sheet just by entering in the number." — User #5
Project Reflection
This project was a rewarding challenge, underscoring the critical balance of safety, efficiency, and user needs in a high-stakes environment. Our research revealed how even small design decisions, when informed by user feedback, could significantly impact user satisfaction and operational efficiency.
