Case Study

Modernizing a Mission-Critical Vehicle Tracking Application While Preserving Institutional Knowledge

Tuscaloosa County faced a critical risk when the sole developer of its mission-critical Automatic Vehicle Locator (AVL) application announced retirement, threatening institutional knowledge and long-term support. Netrix stepped in with a combined development and application management strategy, transferring knowledge, documenting the system, and establishing ongoing support and a development roadmap. The county preserved critical institutional knowledge, kept its AVL platform stable, and freed internal IT staff to focus on higher-priority initiatives.

The Client

Tuscaloosa County's Information Technology Department supports more than 227,000 residents and numerous county departments. One of its most critical systems is the Automatic Vehicle Locator (AVL) application used by law enforcement, emergency personnel, and administrators for real-time vehicle tracking and operational coordination.

The Challenge

The county faced a significant risk when the original developer of the AVL application announced retirement, creating concerns around knowledge transfer, long-term support, and future enhancements. Key challenges included:

  • Loss of institutional knowledge due to developer retirement
  • Mission-critical application requiring near-continuous availability
  • Uncertainty around future development and support
  • Need for accurate budgeting and scope management
  • Requirement for ongoing maintenance and enhancements

The county needed a partner capable of supporting both immediate application needs and long-term operational requirements.

The Solution

Netrix proposed a combined development and application management strategy to support the AVL platform throughout its lifecycle. Key deliverables included:

  • Comprehensive application assessment
  • Knowledge transfer and documentation
  • Ongoing application support services
  • Defined development roadmap
  • Budget and project governance framework

Netrix assumed responsibility for application development and day-to-day support while ensuring critical institutional knowledge was preserved.

The Implementation

  • Extensive discovery and requirements gathering
  • Review of existing AVL architecture
  • Documentation of application logic and processes
