Finally Some Quality Attention to Legacy Systems!
IT trends come and go, but each new technology adds more legacy systems to application portfolios. Legacy systems account for a disproportionate share of IT spending, yet few authors tackle the subject, and even fewer offer actionable advice for capturing and extending the value of those systems. William Ulrich's Legacy Systems Transformation Strategies is a long overdue reference guide for IT professionals seeking to modernize the legacy war horses in their corporate portfolios. Relying on many years of experience in the trenches, Ulrich offers many approaches and options for supporting today's business requirements from data mining to application modularization and EAI (enterprise application integration). He provides concise and practical techniques for all aspects of legacy transformations including planning, data rationalization and business rule capture and reuse. If you own, manage, or support legacy systems, invest in this book! You won't regret it.

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.
