Dr Stephen Castell has worked in all four corners of the IT industry. He was worked on the computing side and in telecommunications. He has worked as a user implementing complex systems and as a vendor of information products and services. He spent years advising UK venture capitalists on what were and what were not the best companies to invest in. Finally he has spent decades as an expert witness in numerous legal disputes between vendors and users when the IT system supplied did not fit the expectations of the buyers. This gives him a unique insight into the failures of IT and today he spent time with Richard Sharpe to talk about his life and career.
