Quite thorough report, some points that stand out from the summary:

>SABIS was TSB’s principal outsourced provider

>SABIS relied extensively on 85 third parties (TSB’s fourth parties) to deliver the systems required for the migration and the operation of the platform, which required it to act as a service aggregator.

It amazes me the sheer complexity of a retail bank software system and I suspect most of it is due to legacy systems, legal requirements and lack of regular spring cleaning.
