The solution enabled the Transportation Safety Agency to:
- Digitize OSRP workflows with tailored PowerApps forms supporting Primary, Secondary, and Resubmission reviews.
- Automate approvals and documentation, including real-time updates to SharePoint lists and dynamic generation of review letters.
- Enhance data quality and auditability by linking form responses to a centralized Priority Table with role-based inputs.
- Meet Prime Contractor and DOE hosting requirements, while staying aligned with the mission of the U.S. Department of Transportation.
Technology Stack & Microsoft 365 Resources

The implementation leveraged Microsoft’s modern cloud suite to ensure agility, maintainability, and long-term compatibility:
- Frontend: PowerApps – for responsive, permission-based forms used across review stages
- Backend: Power Automate – to orchestrate workflow logic, document generation, and escalation alerts
- Data Layer: SharePoint Online Lists – structured repositories for form inputs, review status, and metadata
Cloud Infrastructure:
~ Workflow & Process: Power Automate for sequential logic, triggered correspondence, and task assignments
~ Collaboration & Alerts: SharePoint Groups, Contact Lists, and embedded notifications
~ Governance & Security: Compliance with Microsoft 365 tenant-level controls managed under Prime Contractor, conforming to DOE infrastructure standards
~ Optional Extensions: Integration hooks for SQL-based data storage and reporting (if needed in future phases)
Challenges & Solutions
Challenge 1: Manual, Fragmented Review Workflows
The Transportation Safety Agency’s rail spill response planning involved multiple review stages: Primary, Secondary, Resubmission, and Final, managed manually via email, spreadsheets, and static document versions. This led to inconsistent tracking, unclear responsibilities, and version control issues.
Solution:
- Zirlen designed and implemented structured, role-based PowerApps forms for each review type, replacing unstructured inputs.
- Introduced workflow automation to eliminate manual routing, flagging, and approvals.
- Integrated a centralized Priority Table in SharePoint Online to track plan statuses, key data points, and reviewer assignments in real time.
Challenge 2: Limited Visibility and Delayed Clearance Communication
Coordinating multi-level reviewers across the Transportation Safety Agency and Prime Contractor stakeholders resulted in delayed feedback loops, unclear correspondence flows, and missed notifications, especially at the final clearance stage.
Solution:
- Built automated email triggers and task assignments using Contact Lists and Power Automate.
- Developed a dedicated Correspondence Form that streamlined final review signoffs and notified the OSRP executive assistant upon clearance.
- Established a clear audit trail across SharePoint lists for reviewer activity and plan movement.
Challenge 3: Security, Compliance, and Hosting Constraints
Since the solution operated within the Prime Contractor-managed Microsoft 365 tenant (tied to DOE infrastructure), the implementation had to meet rigorous compliance, access control, and documentation standards.
Solution:
- Configured granular SharePoint permissions, ensuring role-based access for the Transportation Safety Agency reviewers while complying with Prime Contractor/DOE policies.
- Ensured all workflows and data storage conformed to security best practices and internal audit readiness.
- Provided detailed documentation on architecture, workflow logic, custom components, and branding for future audits or enhancements.
