The oil giant kicked off the year by dramatically rationalising hardware and software suppliers with Computacenter and Compuware the major beneficiaries, and is ending 2011 by tendering another mega-deal.

Under the terms of the latest contract signing, HP's existing hosting services tie up with BP in the UK expands to include the remaining data centres in Europe and the Americas.
"By establishing a standardised global operating model, BP will realise immediate cost reductions, improved consistency of service and be well positioned to utilise emerging technologies," said BP CIO Dana Deasy.
The data centre management services include monitoring, back-up, and recovery, site management and maintenance services, database and middleware management.
HP will also give BP the platform to roll out enterprise private and public cloud computing services, HP said.
Mike Nefkens, HP senior VP and GM for EMEA, said it could help BP build an "Instant-On Enterprise" so that technology was embedded in "everything it does".
Only last week, HP signed another mega IT outsourcing deal - data cetre and workplace services - worth £900m with Germany-based energy provider E.ON.
John O'Brien, research director at TechMarketView, pointed out that through the contract, E.ON became the first major energy provider to outsource its entire IT infrastructure.
"Energy companies are under increasing pressure to cut costs and transform their IT estates as they grapple to take on the challenges of smart metering roll outs," he said.
