Safari Rally Timing Software  

The East Africa Safari Rally was the most gruelling of the international rally circuit. Timekeeping too was complicated by poor communications and poor computing infrastructure. Small Business Systems, the ancestor to Unusual Systems, delivered a bespoke software system to manage the leader boards 

Radio operators entered the times of arrival and departure of individual cars at checkpoints across the country, often out of order and after considerable delays. The system calculated which cars were on what leg of the route and their relative positions on the leader board even where data was missing. Results were delivered near-real time to displays in the press suite. The event was largely staffed by scattered volunteers and enthusiasts, and requirements gathering and effective systematic testing was limited. Support over the 48 hour event was therefore crucial and hot-fixes were managed carefully to avoid severely impacting the leader boards.
