5. Information Agility Information agility is the ability to understand, control, and leverage the information assets of the corporation in a useable and readily adaptable manner. Information agility tends to be the "redheaded stepchild" of the SOA strategy. This is unfortunate and needs to be corrected by the SOA governance group, because there is tremendous business leverage in a well thought-out and implemented information strategy as part of the enterprise SOA strategy. It is well known within the IT function at today's enterprises that application integration is a nontrivial problem to solve.

Next, identify the current business groups and their business responsibilities. Interviews with these groups will achieve an understanding of the business functions 45 46 supported and the different market segments within those functions.

Figure 3-4 shows the Operations subset of the TM Forum Business Process Framework.

The usual solution for application integration has been point-to-point interface solutions, as depicted in Figure 3-6. Such solutions, while operationally efficient, result in an ossification of the enterprise business model. It is expensive and risky to change out one application for another or even make changes to an existing application because of the complex nature of the information and functional model. Changes to one system's interface can result in multiple changes and testing of all the myriad systems that must adapt to this change.
