Decision support refers to systems and tools that help individuals or organizations make informed choices. These systems analyze data and present it in a way that highlights important trends, potential outcomes, and risks. By providing relevant information, decision support enhances the decision-making process across various fields, including healthcare, finance, and business management. In healthcare, for example, clinical decision support systems assist doctors by offering evidence-based recommendations for patient care. Similarly, in business, business intelligence tools help managers evaluate market conditions and customer preferences. Overall, decision support systems aim to improve the quality and efficiency of decisions made in complex environments.
