## Question

What are different types of information systems? Differentiate the characteristics of a Management Information System (MIS) and Decision support system (DSS).

## Short answer

Information system types include transaction processing systems, office/knowledge systems, management information systems (MIS), decision support systems (DSS), executive support systems, expert systems, and enterprise systems. MIS provides routine, scheduled summary reports from internal data for structured decisions; DSS provides interactive analysis and models using internal and external data for semi-structured decisions.

## Answer

#### Types of information systems
1. **TPS** - processes daily transactions at operational level.
2. **OAS / KWS** - supports office and knowledge workers.
3. **MIS** - periodic summary reports for middle managers.
4. **DSS** - interactive analysis and models for semi-structured decisions.
5. **ESS** - summarised strategic information for top executives.
6. **Expert system** - rule-based advice in a specific domain.
7. **Enterprise systems** - ERP, CRM, SCM.

#### MIS vs DSS

| Basis | MIS | DSS |
|---|---|---|
| Purpose | Monitor and control operations | Help solve specific, changing problems |
| Decision type | Structured, routine | Semi-structured, non-routine |
| Output | Fixed, scheduled and exception reports | Interactive analysis, simulations, what-if |
| Data | Mainly internal TPS data | Internal and external data plus models |
| Model use | Few or none | Strong use of analytical models |
| Flexibility | Low; predefined reports | High; user-driven |
| User | Middle managers | Managers and analysts |
| Example | Monthly sales summary | Budget planning with scenarios |

## Check yourself

The answer's key points as multiple-choice questions, with the correct option and why.

1. Which decision type does an MIS support compared with DSS?
   A. MIS supports unstructured; DSS supports routine
   B. MIS supports structured, routine; DSS supports semi-structured, non-routine
   C. Both support only routine decisions
   D. MIS supports semi-structured; DSS supports structured
   Answer: B. MIS monitors operations with predefined reports; DSS handles changing problems. (Key point: Decision type)

2. Which describes DSS output?
   A. Interactive analysis, simulations and what-if
   B. Fixed scheduled reports only
   C. Raw transaction records
   D. Printed payroll slips
   Answer: A. MIS gives fixed, scheduled and exception reports. (Key point: Output)

3. Which comparison of data and model use is correct?
   A. MIS uses external data and strong models; DSS uses none
   B. Both use no models
   C. MIS mainly internal TPS data with few models; DSS internal and external data with strong models
   D. MIS uses strong models; DSS uses only TPS data
   Answer: C. DSS combines more data sources with analytical models. (Key point: Data and models)

4. Which is true about flexibility?
   A. MIS is highly user-driven; DSS is predefined
   B. Both are equally rigid
   C. Neither can be changed
   D. MIS has low flexibility with predefined reports; DSS is highly user-driven
   Answer: D. DSS lets users explore, whereas MIS reports are predefined. (Key point: Flexibility)
