Management Information System Notes
- All businesses share information as a common asset.
- Information must be captured, analyzed, and shared to maximize its value.
- An information system (IS) is designed to manage this information.
- A computer-based system providing up-to-date information to management.
- Linked via a network to share data and resources.
- Designed to capture, transmit, store, retrieve, manipulate, and display information.
- Outputs information usable at all organizational levels.
- Management Information System (MIS) serves predictable management functions.
- MIS administration falls under the MIS or IT department.
- ERP and EIS offer enhanced functionality compared to traditional MIS.
Mainframes
- Originally referred to the central processing unit of a large computer.
- Designed for batch processing, later retrofitted for interactive use.
- Experienced a resurgence in the 1990s due to superior performance, reliability and scalability.
The Internet
- Facilitates faster information exchange via web-based systems (intranets, extranets).
- Enables real-time information exchange through web-casting and video conferencing.
- Mobile computing technologies offer further modes of communication.
- Design is based on factors like cost, number of users, modularity, ease of integration, information volume, and computing power.
- Hardware should balance current needs with future requirements.
- System downtime should be minimized to avoid costs and customer inconvenience.
- User access to information should be controlled through user-level permissions and passwords.
- The OSI Seven-Layer Model helps partition computer networks into independent modules.
- Effective communication between IS staff and system users is crucial.
- IS should have a centralized help desk for user assistance.
- Crucial aspects include accounting, financial, manufacturing, marketing, and human resources data.
- The system serves as a library, making stored data accessible and current.
- Software or hardware for sharing data and information internally and externally.
- Enable information exchange and resource searching.
Data Mining
- Analyzing empirical data to extrapolate information for forecasting and trend identification.
- Allow users to find needed information; a common weak point is communication between the MIS department and users.
- Intelligent agents customize information flow through sorting and filtering to suit individual needs.
- Use technology to support the business and facilitate communication.
- Seek strategic advantages in areas like order placement and inventory management.
- Use the system to measure and benchmark performance.
- People are the most important component.
- The system must be usable for the organization’s personnel.
- Pairing the IS department with a training department can bridge the gap between technical staff and non-technical users.
- Identify and train employees likely to adapt to the system.
History of Accounting Machines
- Charles Xavier Thomas credited with starting the calculating machine industry in the 1870s.
- Early innovators included Frank Baldwin and Williams S. Burroughs.
- Mechanical and electronic adding machines dominated until the mid-1900s.
- Examples include Unit record, Tabulating, Billing, and Calculating machines.
- ATMs and POS devices added in the 1980s.
- Computers integrated many devices, rendering older machines obsolete.
The Computer
- A tool managers can use to assist them in generating information.
- An electronic device capable of accepting, interpreting, performing operations on, and reporting data.
- John Von Newman (1946) summarized a modern computer:
- Processing of data instructions using programs.
- Binary codes to represent data and instructions.
- Early accounting machines combined typewriters and calculators.
- Newer machines are often computer-operated.
Uses of Computers
- Computers encompass most mechanical machines into one efficient device.
- accurate record keeping is critical due to minute-by-minute financial changes.
Spreadsheet
- Electronic spreadsheets allow for calculations and "what if" scenarios.
- Used in business and homes.
- A typical integrated double-entry accounting system includes:
- Account receivables
- Account payable
- General ledger
- Inventory order entry
- Payroll
- Time and billing module
General Ledger
- A labor-saving device for preparing financial statements.
Account Receivable
- Computerization allows same-day billing, prepares invoices, handles payments, and identifies delinquent customers.
- Provides daily cases control and avoids billing errors.
Account Payable
- Provides purchase order control, invoice processing, payment selection, cheque writing, and cash requirement forecasting.
Inventory Control
- Tracks inventory for costing and tax purposes, controls purchasing, and minimizes investment.
Payroll
- Processes payroll checks, including deductions, and integrates with the general ledger.
Point of Sale
- Captures sales information at the cash register, produces sales slips, and reports on items and customers.
Purchasing and Receiving
- Generates purchase orders, tracks fulfillment, and identifies vendor performance.
Time and Billing Module
- Reduces manual work, simplifies billing, and provides criteria to analyze staff performance.
Conclusion
- Advancements in technology and information systems have transformed traditional business activities.
- Reduces the pressure on departments like finance and accounting.
- Operational costs have drastically reduced, especially for entities embracing IT.
