Executive Information Systems (EIS)
An Executive Information System is a kind of management information system which is used to support and facilitate the information and decision-making requirements of the senior executives by offering easy access to both external and internal data relevant in order to meeting the strategic objectives of the business or business organization. To a degree, an extension of DSS is executive information systems. EIS is used mostly for highly structured reporting, sometimes referred to as status access. DSS has become almost synonymous with modeling and unstructured, ad hoc querying. Executive-information systems are aimed at senior executives who currently have few, if any, computer-based systems to assist them in their day-today responsibilities. Executive information systems bring together relevant data from various internal and external sources, delivering important information quickly and in a useful way. More important, it filters, compresses, and tracks critical data as determined by each executive end user.
Executive information systems perform the conceptually simple task of informing senior executives on matters relevant to their organizational responsibilities. Unlike traditional MIS functions that focus on the storage of large amounts of information, Executive information systems focuses on the retrieval of specific information and on status access. The emphasis is on reducing the time and effort that the executive user must expend to obtain useful information for making the organization more competitive and its employees more productive. An executive information system can be defined in its broadest sense as one that deals with all of the information that helps executive make strategic and competitive decisions, keeps track of the overall business and its functional units, and cuts down on the time spent on routine tasks performed by an executive. As such, an Executive information system is capable of providing an executive with the right information in the right format, fast enough to enable the individual to make the right decisions.
