20 Integrating Airport Information Systems What data do particular reporting circumstances require? For example, an airport can be part of a municipality that requires certain fiscal data reporting. Case Study Step 1 AIA's CFO approached the CEO with a concern that the airport's current method of calculating rates and charges was cumbersome, prone to errors, and time con- suming. As a result, the CFO felt it would be appropriate to explore the possibility of integrating one or more of the systems that feed data into the rates and charges calculations. The CFO's objective was to improve the process of calculating some or all of the rates and charges by making the process faster, more accurate, and less expensive than the current process. She mentioned several systems and manual procedures that contribute to the calculations. The CEO Agreed and told the CFO to proceed with the initial steps. He noted that major airport goals would be supported by increasing efficiency and reducing costs to the airlines. The CFO identified the intermediate objectives as reducing both staff cost and lost revenue. Step 2: Identify, Define, and Evaluate Information Processes Figure 3-4 indicates the level of effort of the stakeholders for this step. Identifying, thoroughly understanding, and evaluating the information processes are key for any successful integration--after all, this information is the core of the integration effort. First, trace each piece of information identified in Step 1 by answering the following questions: What is the source of the information? How is that information calculated? How accurate is that information? What is the context of that information? Where is that information stored? How is that information tracked? What systems use that information? What people use that information? Why and how do people use that information? Information processes that are sound and provide accurate data before integration will be sound and provide accurate data after integration. Likewise, any information or process that is inaccurate or out of context before integration can provide inaccurate and possibly misleading data after integration. Identify any problems in information processes before taking any other steps Figure 3-4. Step 2.
