Inter-organization DSS are used to serve companies stakeholders customers, suppliers, etc. These systems usually are not data intensive and consequently are not linked to very large databases.

Executive dashboard and other business performance software allow faster decision making, identification of negative trends, and better allocation of business resources. In short, the information needs for different levels of management are directed towards supervisory functions for lower management, tactical decision making for middle management and strategic decision making for top management.

DSS is built on top of a transaction system, a database and a data model, all of which provides the DSS with data and information that is processed and presented to the user in a simplified form.

Due to the large amount of variables that surround the projected revenue figures, this is not a straightforward calculation that can be done manually. There are multiple factors that qualify information as having good quality such as timeliness, relevant, accurateness, consistency, unbiased, etc.

Top management commonly use information to make decisions about long term planning and thus analyze long term trend information to make their decisions Gore et al, They define DSS broadly as an interactive computer based system that help decision-makers use data and models to solve ill-structured, unstructured or semi-structured problems.

Consequently our discussion on databases will parsimonious at best. Moreover, because the DSS are employed to improve management control, it should address the primary tasks of management control. Document driven These systems help managers retrieve and mange unstructured documents and web pages by integrating a variety of storage and processing technologies to provide complete document retrieval and analysis.

Transformed data from which DSS "decisions" are generated Decisions: This level makes use of case tools or systems such as Crystal, Analytica and iThink. Knowledge driven DSS are often referred to as management expert systems or intelligent decision support systems.

The flexibility of the DSS is extremely beneficial for users who travel frequently. For example, one of the DSS applications is the management and development of complex anti-terrorism systems. GDSS supports electronic communication, scheduling, document sharing and other group productivity and decision enhancing activities and involves technologies such as two-way interactive video, bulletin boards, e-mail, etc.

Decision Support System - DSS

Due to DSS all the information from any organization is represented in the form of charts, graphs i. Applications[ edit ] DSS can theoretically be built in any knowledge domain. DSS generators including special languages, function libraries and linking modules An iterative developmental approach allows for the DSS to be changed and redesigned at various intervals.

Amongst the common ones are the following: Unlike information, which often relates only to specific instances, knowledge is contend-rich and re-usable and should thus be captured whenever possible to provide a point of reference for future similar scenarios.

The latter, because of their stricter control, are often stand-alone units inside the firm.

decision support system (DSS)

Precision agriculture seeks to tailor decisions to particular portions of farm fields. DSS components may be classified as: It is a common notion that information can be and often is… misinterpreted, leading to inaccurate conclusions which adversely affects the quality of the decision making process inside an organization as is humoristically depicted in figure 1….

Not every DSS fits neatly into one of the categories, but may be a mix of two or more architectures.

Decision support system

Intelligence — Searching for conditions that call for decision; Design — Developing and analyzing possible alternative actions of solution; Choice — Selecting a course of action among those; Implementation — Adopting the selected course of action in decision situation.

A DSS can generate information and output it graphically, such as a bar chart that represents projected revenue, or as a written report.

A problem faced by any railroad is worn-out or defective rails, which can result in hundreds of derailments per year. Having summarized the most important functions of a DSS, it should be remembered that a DSS is only as good as the individual components that it consist of: This is different from an operations application, which would be used to collect the data in the first place.

One example is the clinical decision support system for medical diagnosis.The benefits of a decision support system (DSS) can be subtler than those of other systems. This chapter identifies benefits from various DSSs as described in the literature and categorizes them. I. Introduction In the DSS literature, experts prescribe a variety of approaches or methodologies for designing and developing Decision Support Systems.

Information Systems Analysis Topic: Decision Support Systems. Randall E. Louw. They define DSS broadly as an interactive computer based system that help decision-makers use data and models to solve ill-structured, unstructured or.

In John D.C. Little noted that the requirement for designing models and system to make a management decision was completeness to data, simplicity, ease of control and robustness, which till date are relevant in improving and evaluating modern DSS’s.

Decision Support System • A computer-based information system that supports business or organizational decision-making activities. • OR • Interactive computer-based systems, which help decision makers utilize data and models to solve unstructured problems.

A decision support system (DSS) is a computer program application that analyzes business data and presents it so that users can make business decisions more easily. It is an "informational application" (to distinguish it from an "operational application" that collects the data in the course of.
