Management Information System Notes

Organization of Management Information System

  • 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.

Information System

  • 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.

Information System Design and Administration

  • 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.

Information System Documents and Record Management

  • Crucial aspects include accounting, financial, manufacturing, marketing, and human resources data.
  • The system serves as a library, making stored data accessible and current.

Collaborative Tools

  • 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.

Query Tools

  • 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.

Key Points about Information System

  • 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 keepingaccurate\ 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.
