Decision Support refers to a set of tools, techniques and processes used by organizations to help managers make better decisions. It involves using data analysis, modeling, simulation, and other analytical methods to provide relevant information that can be used in decision-making. The goal is to improve the quality of decisions made by providing timely, accurate, and useful information to support informed choices. Decision Support systems are often computer-based but may also involve human experts who analyze data and provide insights. They play a critical role in helping organizations make better decisions faster, which can lead to improved performance and competitive advantage.
