It is very important to establish why both vendor and end-user communities within the IT industry are going through the trouble of adopting the service-oriented computing platform and embracing all of the change that comes with it.
The vision behind service-oriented computing is extremely ambitious and therefore also very attractive to any organization interested in truly improving the effectiveness of its IT enterprise. A set of common goals and benefits has emerged to form this vision. These establish a target state for an enterprise that successfully adopts service-orientation.
The upcoming set of sections describe each of these strategic goals and benefits (also displayed in Figure 3.26):
Figure 3.26 The seven identified goals are inter-related and can be further categorized into two groups: strategic goals and resulting benefits. Increased organization agility, increased ROI, and reduced IT burden are concrete benefits resulting from the attainment of the remaining four goals.
Increased Intrinsic Interoperability
Increased Federation
Increased Vendor Diversification Options
Increased Business and Technology Domain Alignment
Increased ROI
Increased Organizational Agility
Reduced IT Burden
It is beneficial to understand the significance of these goals and benefits prior to studying and applying service-orientation so that design principles are consistently viewed within a strategic context.
An important message of this book in general is that there is a concrete link between successfully applying service-orientation design principles and successfully attaining these specific goals and benefits (a point which is further detailed in Chapter 16).
