2.15 Our analysis of key strategic decisions made during the course of the programme points to three main features of Crossrail Ltd's management of the programme that led to cost increases and the current uncertainty about what the programme will cost and when it will be completed. They are:
• Crossrail Ltd's delivery and commercial strategy;
• the build-up of delays, dependencies and interfaces between contracts and projects; and
• not changing course when there were clear signs that the programme was not on track.
