The concept of agility has been in existence for more than a decade.  Several techniques such as modular designs and component-based architecture have been tried.  These techniques and their variants to improve agility did not fully address the two key factors namely, quickness and inexpensive, essential to maximize the business value.  Lack of agility resulted in underutilization of traditional process-oriented systems. Service Oriented Architecture to process-oriented system integration offers hope in addressing the key factors.
