Previous chapters discussed what SOAs are and provided technical details of their implementation. We now focus on the challenge of actually introducing an SOA into the enterprise. This chapter addresses the general motivation and the main benefits to be expected. Subsequent chapters discuss strategies for successfully introducing an SOA into an enterprise and for project management. This chapter consists of two major parts. Section 11.1 begins with a discussion on enterprise-level goals in order to round off this topic that we saw first in Chapter 1, "An Enterprise IT Renovation Roadmap." The pressure on organizations to become more agile and efficient is a major driving force in the introduction of an SOA, as is the inflexibility of existing IT infrastructures composed of monolithic applications. Section 11.2 describes the viewpoints of the individual stakeholders and considers the interests of the actual people and roles involved in the endeavor of introducing an SOA. |
