Since it's inception, the marketplace for information technology services has been characterized by continual re-invention, from installation services and maintenance, to data center outsourcing to managed and hosted operations, to applications services, strategy consulting, and now emergent value propositions around building new business flexibility via Service Oriented Architectures, or the opportunities of global integration and talent. One constant: the requirement that services providers respond to client requirements at either end of the client's strategic agenda -- from efficiency/productivity initiatives, to higher-value and even industry-changing competitive programs.
