INFORMATION FOR MANAGEMENT
1.1 Data and Information, types of information : Operational, tactical, strategic, Statutory
1.2 Why do we need information systems, management structure, requirements of information at different levels of management
1.3 Functional allocation of management, requirements of information for various functions.
1.4 Qualities of information
1.5 Varieties of information system
MOTIVATION
Large number of jobs today for computer science and engineering graduates is in creating information systems for managing organizations
Students should know what is information and how it is different from data
Should know types of information needed to manage organizations
LEARNING GOALS
Distinction between Data and Information
Description of types of Information: Tactical, Operational, Strategic, Statutory.
Division of Management into different hierarchical

INFORMATION FOR MANAGEMENT
Identifying and controlling areas of high cost.
Identifying critical bottlenecks in production.
Identifying alternate production schedules
based on tools, machines etc.
Performance measures of machines to decide
replacement
MANAGEMENT INFORMATION SYSTEM
Analyse outputs of routine data processing using
statistical or operations research tools
Eg: -Observe periodic demands by statistical analysis &
use for tactical decisions
-Use operations research tools to decide product mix
using demand and cost data to maximize profit
DECISION SUPPORT SYSTEM
Unstructured and difficult to obtain precise information
Use of analytical and simulation models
Aids to conceptualise through graphs ,animation etc
Use of archival data to infer trends and rules
Some artificial intelligence tools may be used
