Historical Context
The concept of Executive Information Systems (EIS) dates back to the early 1980s when the rapid advancement of computer technologies and information systems made it possible to provide top executives with real-time, concise, and relevant information for strategic decision-making. EIS evolved from the earlier Decision Support Systems (DSS) and Management Information Systems (MIS), focusing more on providing a high-level overview of the organization’s data.
Types/Categories
- Operational EIS: Monitors day-to-day operations, providing real-time data to executives.
- Tactical EIS: Supports middle management in short-term planning and monitoring.
- Strategic EIS: Aids top executives in long-term decision-making and planning.
Key Events
- 1980s: Introduction and development of EIS by companies such as IBM and DEC.
- 1990s: EIS integration with emerging technologies such as data warehouses and online analytical processing (OLAP).
- 2000s: Evolution into modern Business Intelligence (BI) tools incorporating big data and analytics.
Detailed Explanation
An Executive Information System (EIS) is a specialized form of Management Information System designed to support the informational needs and decision-making processes of senior executives. Unlike typical data systems, EIS aggregates and summarizes company data across various departments, providing a high-level view conducive to strategic planning.
Mathematical Models/Formulas
While EIS primarily focuses on data visualization and aggregation, it often incorporates various mathematical models and formulas such as:
- Predictive Analytics:
$$ P(Y|X) = \frac{P(X|Y) \cdot P(Y)}{P(X)} $$
- Linear Regression:
$$ Y = a + bX $$
