IT胜利：向一个新的信息技术模式挺进 IT Success! : Towards a New Model for Information Technology 下载 pdf 百度网盘 epub 免费 2025 电子版 mobi 在线

“Fifty years after the birth of corporate computing, IT today is still characterized by 50-70% project failure rates. Which is pretty scary when you come to think of it: either a goblin has cast a spell on a whole profession – or that profession is doing something fundamentally wrong”.

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.
