We can always learn from peoples mistakes and this one is a classic.
When TFL awarded the Oyster card managed services contract to Transys they appear to have failed to write into the contract the following:
- Details of termination and handover
- Brand ownership
Consequently on 2010 they face some pretty hefty costs associated with re-branding there offering, issuing new cards and infrastructure.
Moral of the story it might seem a long time off when signing a 10+ year contract and you may not be around, however if you are calling yourself professionals the contract should cover this future event.
