Looks like someone painted themselves into a corner
A great place for an incumbent to be - (relatively) short contract extension on a complex, ageing system.
This means the list of potential providers will be short, the cost of change (hard cost and disruption) will be great and the risk high.
Contracts often have extension clauses in them (good ones anyway) which may cover prolonged procurement cycles.
I wonder why they are not going for a replacement system now, however.
