## Question

Explain about Enterprise and Executive decision support systems (DSS) with examples.

## Short answer

An enterprise DSS is an organization-wide system built on a data warehouse serving many users with OLAP, dashboards and mining, for example a bank-wide analytics platform. An executive DSS supports senior executives with strategic decisions through dashboards, KPIs, drill-down and external data, for example a CEO revenue dashboard.

## Answer

#### Enterprise DSS
An **Enterprise (or organization-wide) DSS** is a large-scale decision support system built on the enterprise data warehouse and network, serving many decision makers across the organization. It integrates data from ERP, CRM and other systems and offers OLAP, reporting, dashboards, data mining and modeling to all levels.

Features: shared data warehouse, web access, supports many users and functions, consistent data.
Example: a bank-wide analytics platform used by branch managers, risk officers and marketing for loan and customer analysis.

#### Executive DSS (Executive Information / Support System)
An **Executive DSS (EIS/ESS)** is designed for senior executives' strategic, unstructured decisions. It gives easy, summarised, graphical access to internal data (sales, finance, performance) and external data (market, competitors, news).

Features:
- Dashboards, key performance indicators and the balanced scorecard.
- **Drill-down** from summary to detail.
- Exception reporting and trend analysis.
- Simple interface (touch, graphs), fast response.
- Soft and external information.

Example: a CEO's dashboard shows monthly revenue by region in colours; red regions can be clicked to see branches and products.
