'Information Technology is like fire. It has the power to transform or destroy companies.' All senior managers are making strategic decisions driven and enabled by the capabilities of information technology. Finally there is a clearly written and accessible book for senior managers to understand the underlying technologies that will drive their businesses. Senior managers should add this book to their management tool kit for daily reference in shaping competitive strategies. Peter Weill, Director, Center for Information Systems Research, Sloan School of Management, MIT Understanding IT: A Managers Guide by Dave Aron and Jeffrey L Sampler offers you the opportunity to become familiar with not only information technologies of today, but also the technology of the future. Written in an engaging style, the book explains IT concepts with superb clarity. In this way it serves as the driving force that will enable you to successfully exploit existing technology and to realize the potential of emerging technologies in your organization. ...Now, more than ever, general managers must strive to understand technology, in order to ensure that it is well implemented in their organisations, and to inform their corporate strategy. We will continue to see those that succeed in this achieve greater success than those who treat IT as a black box and 'leave it to the IT department'. I have had to acquire my understanding of the IT sector through experience and application. I wish I'd had this book as the starting point in that process! David Levin, CEO, Symbian Ltd Understanding IT: A Managers Guide is an ideal companion for general business managers and for students of management, particularly at MBA level. Enthusiasm for the subject shines through and helps make for a stimulating read.
