The document discusses lessons learned from the launch of Transantiago, the bus rapid transit system in Santiago, Chile. Key challenges included the system lacking readiness in infrastructure, fleet, and ticketing systems. There was also a lack of adequate planning and testing prior to launch. The document then provides guidance on developing operational manuals to minimize risks for new bus system launches. It suggests the manual define processes, responsibilities, indicators, and contingency plans. The goal is to ensure a smooth start-up that improves public perception and quality of service. Adaptations may be needed for contexts in Africa, including additional infrastructure considerations.
