Linux has reached a critical mass--no technical manager with budgetary responsibility can afford to ignore the possibility for significant cost benefits. This book takes the reader through the process of systematically examining the potential uses for open source in their computing environment. It explains how to estimate the cost benefit to prepare a justification for further investigation. Worksheets enable readers to quickly and easily evaluate the feasibility and return on the investment of any migration project. This book includes information on the best professional-quality, low-cost software for Linux, with dozens of listings that include where to download and where to find support. Case studies demonstrate ways open source has been successfully deployed by peers.
