Given the recent public failures of large ICT/IM projects, it is timely to review the traditional customer supplier model. For those using PRINCE2 for project delivery you may find this article quite informative.

Although it may seem obvious, it is key for the Customer Project Manager to maintain appropriate checks and balances with both the Customer Team Manager and Supplier Project Manager.

Failure for IT groups to adopt these principles I believe will result in IT being completely sidestepped when the business wants to implement a new initiative due to the era of cloud computing.
