A new payments system was recently implemented to replace an old legacy system.

 The scenario describes a situation where there is a discrepancy between the system users’ perception and the system performance statistics regarding the new payments system. The BA needs to demonstrate to the users how the new system is performing and address their complaint. The best way to do this is to collect system metrics and communicate the results in an understandable format. System metrics are quantitative measures that indicate the performance, quality, and efficiency of the system. Communicating the results in an understandable format means using clear and simple language, charts, graphs, or tables to present the data and explain the benefits of the new system.
