2. MIS Definition
A computer-based system that makes information available to users with similar needs. 2

3. Early MIS Efforts Popular in business by the mid 1960s
Punched card and keydriven machines were used only for data processing
The first computers were applied the same way
Only a few computer literate people in the firms 3

4. MIS is an Organizational Resource
Information
Past, present, future
Periodic reports, special reports, simulations
Similar needs
Functional area
Management level
Managers and nonmanagers 4

8. Report Writing Software
Periodic and special reports may look the same, the difference is in what triggers the report
periodic report - produced on a schedule
special report - produced when something out of the ordinary occurs

9. Incorporating Management by Exception
Prepare the report only when exceptions occur
Use the report sequence to highlight exceptions
Group exceptions together
Show the variance from the norm

12. Mathematical Modeling
Models are abstractions
Models may be:
static or dynamic
deterministic or probabilistic
optimizing or suboptimizing

13. Simulation Use of a model is called simulation
‘Scenario’ - conditions that influence the model
Decision variables are input values
Output format varies

14. Graphic Output Use graphics to present a quick summary
detect trends over time
forecast activities
seek relatively simple impressions from a large volume of data 14

15. Graphic Output (continued)
Types of graphs to use
line or bar charts to summarize data
grouped line or bar charts for trends
grouped bar charts for representing parts of a whole
compare variables using horizontal, not vertical, bars
single line or bar charts to compare data points

19. Putting the MIS in Perspective
The first attempt to make information available to management
Enjoyed its greatest prominence in the 1960s when it first originated

20. The MIS and Problem Solving
Contributes because MIS is an organization-wide resource
Contributes because it keeps a continuous supply of information to the manager for problem identification and understanding
