More About This Title It Success ! - Towards a New Model for Information Technology
English
IT Success! challenges the widespread assumption that an IT department is like a building contractor whose project managers, architects and engineers (all construction industry terms…) are supposed to deliver systems on schedule, within budget and to spec. Michael Gentle explains why this is not possible, and turns conventional wisdom on its head by showing that:
- you cannot define an IT project in terms of contractual budgets and schedules
- anything can change during the life of a project
- what is eventually delivered can never be what is actually needed
He proposes a new model for IT in which the traditional client/vendor relationship, with its contractual commitments, is replaced by a shared risk/reward partnership geared towards workable results over time. Using real-world examples and a case study, the author walks you through the end-to-end processes of an IT department, covering subjects like demand management, investment planning, agile development and managing production applications.

Michael Gentle has over 25 years of experience in IT departments, consulting companies and software vendors in Europe, North America and Asia-Pacific. He brings a refreshingly new angle to an old problem - and directly challenges both IT professionals and business executives to think differently about how to achieve IT success.
