After spending more than 20 years at the IT coal face across a variety of industries, often in finance-related roles, Dennis Howlett is using that accumulated experience to hold vendors to account for what they deliver to customers. He believes the cloud computing model provides the potential to offer transformational business benefits that have yet to be fully understood or articulated. In early 2011, Howlett celebrated 40 years in and around IT. It was a very small party.
