No silver bullets when dealing with legacy systems!!
Corporations have been trying to retire legacy systems for the past couple of decades. Each new technology (be it client/server, ERP packaged apps, etc) were supposed to put the nail in the coffin for legacy systems. Yet, legacy systems continue to thrive despite attempts to retire them. One reason why they continue to exist is that in many instances, they support business processes in the most efficient and cost-effective manner possible. Bill's book views this area more as a transformation effort (evolution) rather than wholesale legacy replacement (revolution). This book is a must read for IT departments as they struggle to remain relavent in an era of outsourcing.
The strategies outlined in this book will help the IT department become a partner with functional business units in delivering solutions that address burning business problems. The focus shifts to providinig measurable value to the business as opposed to implementing unified and elegant technologies.

Timely guidance in hectic times
Mr. Ulrich understands how businesses have a tremendous reliance on legacy systems. Pressure is always on the IT staff to meet the demands of the business cusomter. The IT community is asked to bring products and services to the consumer through the internet while managing the internal demands to keep expenses under control. Bill's book lays out a framework in which the business community can build company-specific plans to leverage their prior investments while striving to meet today's business drivers in a manner that is cost effective.
