MIS vs. DSS Management Information Systems vs. Decision Support Systems
MIS: The Big Picture
MIS provides information about the performance of an organization Think of entire company (the firm) as a system. An MIS provides management with feedback
MIS: The Big Picture
The Firm Processing Input: Raw Materials, Supplies, Data, etc.
MIS Managers, VPs, CEO
Output: Products, Services, Information etc.
MIS: Feedback for a Firm
Q: How are we doing? A: Look at the report from the MIS
Generic reports: Sales, Orders, Schedules, etc. Periodic: Daily, Weekly, Quarterly, etc. Pre-specified reports
Obviously, such reports are useful for making good decisions.
How is a DSS different? MIS DSS Periodic reports Special reports that may only be generated once
Pre-specified, generic reports
May not know what kind of report to generate until the problem surfaces; specialized reports.
MIS vs. DSS: Big Differences
In a DSS, a manager generates the report through an interactive interface
Flexible & Adaptable reports
DSS Reporting is produced through analytical modeling, not just computing an average, or plotting a graph.
Business Models are programmed into a DSS
Types of Decisions Operational Unstructured
Tactical
Cash Re-engineering a Management process
Strategic New e-business initiatives Company re-organization
Semistructured
Production Scheduling
Structured Payroll
Employee Performance Mergers Evaluation Site Location Capital Budgeting

Support
Info about performance
Info and modeling to analyze problems
Report Form
Periodic reports or On Demand Pre-specified Fixed format
Interactive Inquiries
Processing Extract and manipulate data
Analytical modeling of data
Format
Flexible and Adaptable
What is Analytical Modeling? Examples Supply Chain Modeling – Simulate what would happen if you reduced your inventory?
How many items would go out of stock? How much would you save? Is reducing inventory a good thing?
More Modeling Price Point Modeling – model what would happen if you lowered or raised the price of your product uses information about
your customers income and your competitors prices
uses well-know supply and demand models
Typical MIS Reporting
Periodic Scheduled Reports
Exception Reports
Example: Monthly Financial Statements Example: List of items out of stock
These reports contain information but they might not directly help you determine the best decision to make.
More MIS Reports
Demand Reports and Responses
Push Reporting
Available whenever a manager needs them, updated in real-time. Information is pushed to a managers computer Example: Report is pushed every time a supplier is late with a shipment
MIS Reporting is all about giving managers feedback and doesn’t necessarily help directly with decision making.
How is DSS reporting different?
Modeling helps predict the outcome of a decision. This directly helps you make a decision
Possibly an optimal decision
With a DSS you can explore possible alternatives.
Analytical Modeling is the key Type of Modeling What-if analysis
Example
Sensitivity analysis Goal-seeking analysis
Let’s cut advertising by 1% repeatedly so we can see its relationship to sales Let’s try increasing advertising until sales reach $1 million
Optimization analysis
What level of advertising maximizes our overall profit?
What if we cut advertising by 10% what would happen to sales?
