JKR Corporation has a lot of data in its AIS; it wants to use a data analytics tool to make sense of it. Requirements analysis. The tool must be comprehensive and widely used in similar organizations. Here’s an example of how to apply the SDLC in accounting information systems. Systems development life cycle Design. JKR wants to use decision trees, neural networks and various statistical tests to analyze its data. Build. Rather than creating a tool from scratch, JKR evaluates several data analytics packages from various vendors: Excel, SAS Enterprise Miner and SAP HANA. Here’s an example of how to apply the SDLC in accounting information systems. Systems development life cycle Test. After examining each package, JKR chose SAS Enterprise Miner. The software is installed on a few computers; users provide feedback on training and customization issues. Here’s an example of how to apply the SDLC in accounting information systems. Systems development life cycle Implementation. JKR installs SAS Enterprise Miner throughout the organization, and provides training to . | Chapter 5 Information Systems Concepts Outline Learning objectives Systems development life cycle Capability maturity model IT decision factors Learning objectives List and discuss, in order, the steps in the systems development life cycle.
