Text C: Evaluation and selection. Application specifications

To determine the best solution, the project team devises a list of criteria comparing each potential solution. This list includes general criteria related to costs, benefits, and development time. It also includes technical criteria such as the flexibility of the solution and its adaptability for future modifications. Finally, the list includes functional criteria that indicate how well the solution satisfies the specified requirements.

After the project team selects a solution, the next task is to select the hardware and software. The basis for choosing hardware and software includes general criteria, such as cost and delivery time. Technical criteria for hardware might include processing speed, reliability, upgradability, maintenance cost, and warranty. Technical criteria for software might include reliability, compatibility, and availability of patches to fix program errors.

Next step depends on the type of solution selected. If the project team selects a solution that requires programming, systems analysts will create a set of application specifications that describe the way the information system’s software should interact with users, store data, process data and format reports.

Application specifications are a key element in developing an effective information system. They are similar to the pages of the architectural blueprint that show the detailed plan for electrical wiring or plumbing. Not only do these specifications serve as a blueprint for the new system, but they ensure that the development process proceeds efficiently.
