Introduction

This unit will deal with the following issues:

	In today's business on demand, to provide a higher level of services at a lower cost for the business to
	compete and succeed, IT (Information Technology Systems) has to build more complex, flexible, scalable,
	extensible, and forward-thinking technical solutions, to meet the ever-growing business needs.

	This chapter defines a methodical approach, named model-centric architecting process (MAP), to effectively
	cope with the architecture design complexity and manage the architecting process and lifecycle of information
	systems development in a service-oriented paradigm.
