Decision Support systems are capable of converting business data into actionable insights, which are then effectively communicated through reports and dashboards.
These insights serve as a foundation for management teams and managers to make informed decisions, leveraging the data stored within business systems to enhance operational efficiency and decision-making processes.
Decision Support, often synonymous with “Business Intelligence,” can use rule-based AI methods but is primarily recognized for its role in extracting and presenting data for strategic decision-making.
Decision Support System (DSS)
A decision support system (DSS) is a computer program designed to enhance a company’s decision-making processes. It works by analyzing extensive datasets and presenting the organization with the most favorable options available.
DSS integrates data and knowledge from diverse sources to offer users insights beyond standard reports and summaries, empowering them to make well-informed decisions.
A Decision Support System (DSS) could be employed to forecast a company’s revenue for the next six months, using updated assumptions about product sales.
This task is complex due to the numerous factors influencing revenue projections, making manual calculation impractical.
Nonetheless, a DSS can integrate multiple variables, producing both primary and alternative revenue forecasts. These predictions are grounded in the company’s historical sales data and present conditions, enabling a comprehensive analysis of potential outcomes.
A decision support application typically gathers and presents various types of information to aid in decision-making. This can include:
- Comparative Sales Figures: Providing insights into sales performance by comparing figures from different time periods, such as one week to the next, to identify trends and patterns.
