Re-engineering a Credit Card Authorization System for Maintainability and Reusability of Components - A Case Study
نویسندگان
چکیده
A credit card authorization system (CAS) is a large information system performing diverse activities such as purchase authentication, balance transfer, cash advances, etc. One characteristic of CAS is its frequent update to satisfy the needs of customers and newly enforced governmental laws. Thus, CAS should be designed to minimize the effects of updates, for which high reusability of the CAS components is desired. In this paper, we present our experience of re-engineering CAS based on a feature model for improved reusability of components, which alleviates the difficulty of system maintenance. The result of this project has been successfully transferred to the company.

The life cycle cost of a system is influenced by its maintainability. Maintainability is a design parameter, whose operational conditions can affect it significantly. Hence, the effects of these operational conditions should be quantified early in the design phase. The proportional repair model (PRM), which is developed based on the proportional hazard model (PHM), can be used to analyze mainta...
