Using I.S. for Decision Making

7 Mar

This blog is regarding various other parts of support systems that help in decision making. Decision Support Systems (DSS) are a specific class of computerized information system that supports business and organizational decision-making activities. A properly designed DSS is an interactive software-based system intended to help decision makers compile useful information from raw data, documents, personal knowledge, and/or business models to identify and solve problems and make decisions.

Typical information that a decision support application might gather and present would be:

  • Accessing all of your current information assets, including legacy and relational data sources, cubes, data warehouses, and data marts
  • Comparative sales figures between one week and the next
  • Projected revenue figures based on new product sales assumptions
  • The consequences of different decision alternatives, given past experience in a context that is described.

    Executive Support System (ESS) is a reporting tool (software) that allows you to turn your organization’s data into useful summarized reports. These reports are generally used by executive level managers for quick access to reports coming from all company levels and departments such as billing, cost accounting , staffing, scheduling, and more.

    In addition to providing quick access to organized data from departments, some Executive Support System tools also provide analysis tools that predicts a series of performance outcomes over time using the input data. This type of ESS is useful to executives as it provides possible outcomes and quick reference to statistics and numbers needed for decision-making.

    The exact reporting tools and outcome of an Executive Support System completely depends on the ESS developer and it’s intended industry use. For example, Cambridge Systematics has ESS to support the investment planning process for the Ministry of Transportation. The features and functions of this Executive Support System are entirely different from the Executive Support System developed by Meditech, which is useful to health care organizations.

 A Group Decision Support System (GDSS) is an interactive, computer-based system that helps a team of decision-makers solve problems and make choices. GDSS are targeted to supporting groups in analyzing problem situations and in performing group decision-making tasks. The name is very descriptive. A GDSS is a hybrid system that uses an elaborate communications infrastructure and heuristic and quantitative models to support decision-making.
