Systems planning, design and implementation

Information systems (IS) are developed for different purposes, largely depending on human and business needs. The variety of systems that may be developed range from, for example, operational level transaction processing systems (TPS), to managerial planning control level using office automation systems (OAS), to strategic level using decision support system (DSS). In addition, enterprise resource planning (ERP) is an important system type that provides integrated applications to manage the business and automate many back-office functions related to technology, services and human resources. The key point is that different IS serve different purposes, often directed at various management levels within an organisation. As users adopt new technologies, system analysts are typically tasked with integrating traditional systems with new solutions, e.g. web systems, cloud-based systems or wireless systems. The systems analyst uses analysis and design techniques to solve specific business problems using IT solutions. With any new system, there are several questions which managers may question, for example: How many systems development approaches are there to addressing our core problem? What is the best approach to implement AIS? How can it be ensured that system output will meet user needs? Where should AIS data be stored, e.g. on-site or in “the cloud”? How should data be organised and accessed? What privacy concerns could our customers have with different data access options? Should mobile accessibility options be considered?.
