For those who have never seen a decent sized project go wrong from the inside, DE BEERS UK LIMITED (Formerly: THE DIAMOND TRADING COMPANY LIMITED) vs. ATOS ORIGIN IT SERVICES UK LIMITED provides a well written example. De Beers contracted Atos to write some software. The development of the software did not go well. Were the original requirements/spec underdone or were subsequent personnel not up to the job? Difficult to tell from the Decision, as is the reason Atos thought they had a chance of winning a court case.
SAP UK LIMITED vs. DIAGEO GREAT BRITAIN LIMITED was a licensing dispute, or more accurately an example of why it is important to check what your third-party software gets up to.

The end result was a bill for £55 million, which Diageo had not been expecting.
