Decision support systems (DSS) are information systems that combine data, models, and analysis to aid human decision-making. They provide structured information, scenario simulations and recommendations for business and public-sector decision makers and can integrate rule-based as well as analytical methods. DSS typically emphasize data integration, interact…
Use this profile to understand the building block briefly, place it in the model, and switch to the 360° assessment when needed.

What you need to understand to reason about a domain.
Decision support systems combine data, models, and interaction to structure and improve human decision-making in organizations.
The concept grew out of research on organizational decision making at the Carnegie Institute of Technology in the late 1950s and early 1960s. DSS became a distinct research area in the 1970s; the 1980s added executive, group, and organizational variants. From about 1990, data warehousing and OLAP broadened the approach toward wider analytics.
Think of a DSS as a three-layer bridge between raw data and a decision. At the bottom are operational systems, documents, and tables. In the middle, models, rules, and analytic methods condense the information and simulate scenarios. At the top, the decision maker compares options, adjusts assumptions, and turns the results into a justified action.
Data from multiple sources is brought together and normalized for analysis.
Domain logic, statistical methods, or heuristics represent decision relationships.
Users can vary assumptions and compare the consequences of different options.
DSS are especially useful when part of the decision can be formalized while other parts remain open.
Results must be explainable so they can be reviewed, discussed, and assigned responsibility.
DSS help with planning, approval, and prioritization decisions when multiple data sources, uncertainty, and conflicting goals come together. They are especially useful in management, operations, controlling, and public administration. Limits lie in data quality, model assumptions, and maintenance effort; a DSS supports decisions, but it does not replace professional responsibility.
