Preface

Competition in the future, even today in certain industries, will not be company against company but supply chain against supply chain. Companies will be only as strong as the weakest link in their supply chain. The winners will be companies that can build electronic B2B relationships rapidly and manage those relationships seamlessly.

To cope in this new world, businesses need more agility. But to get this agility, they need a well-designed IT infrastructure that is highly reusable and adaptive. An agile, adaptive infrastructure can help businesses turn on a dime and capture new opportunities as they arrive.

Enriching the Value Chain: Infrastructure Strategies Beyond the Enterprise explains how adaptive infrastructure techniques can create a more focused, organized approach to delivering and supporting high-agility applications for e-Business and beyond. Along the way, the book recommends best practices for dealing with architecture and technology issues within the infrastructure in a way that can lead to success.

Moreover, the book highlights the e-Business-centric infrastructure strategies that will become key internal strategies as well. The days of separate e-Business infrastructure design and delivery are waning, to be replaced by more codependent and jointly developed internal and external infrastructure solutions.

From an infrastructure perspective, the "e" is actually disappearing so that e-Business will become just plain business. Soon, creating a design for inter-nal corporate infrastructure will involve nothing more than dropping a few requirements from high-level e-Business designs. If these internal solutions later need to be reused externally, the infrastructure will already be in place for a simple incremental upgrade to the e-Business level. And e-Business infrastructure will not be all that different from what we now think of as traditional enterprise computing.
