A decision support system (DSS) is a computer-based information system that supports business or organizational decision-making activities. It can handle large amounts of data from different sources, provide flexible reporting and presentations, and perform complex analysis and comparisons using advanced software. DSSs serve management, operations, and planning levels of an organization by supporting activities like sensitivity analysis, "what-if" analysis, and goal-seeking analysis to evaluate alternative decisions and help choose the best option. The example described is a DSS used at RUKMANI BAJAJ in Indore to help the CEO and management make informed decisions.
