This completely revised, fourth edition of The Design Selection & Implementation of Accounting Information Systems focuses on AIS concepts that make students more marketable in the current accounting environment. Today, more than 90 percent of accounting systems are commercially licensed. This has driven a market demand for accounting graduates who can install, operate, and audit commercial accounting information systems. In contrast to traditional accounting systems texts that emphasize systems development, this text gives students the theoretical foundation and skills to conduct a requirements analysis, search for a commercial solution, and successfully implement the software package selected. The authors combine a strong presentation of essential AIS concepts with numerous examples of leading commercial accounting systems software.
