Study Notes

Processing Integrity and Availability

  • Integrity checks data for accuracy, completeness, and correctness
  • Availability ensures data is usable for operations needs
  • Integrity is broken down into three components: inputs, processing, and outputs

Input Controls

  • Form design minimizes data entry errors

  • Sequential pre-numbering verifies no documents are missing

  • Turnaround documents eliminate errors by returning documents for completion

  • Cancellation data prevents duplicate entries

  • Automated entry controls include:

    • Field checks verify data in fields is correct
    • Sign checks ensure data follows expected signs (positive/negative)
    • Limit checks prevent exceeding maximum or minimum limits.
    • Range checks verify data within specified ranges
    • Size checks verify appropriate data size
    • Completeness checks ensure all required data is present
    • Validity checks compare data to a master file for accuracy.
    • Reasonableness test validates data for logical consistency
    • Check digit verification verifies data entry accuracy.

Batch Processing Controls

  • For processing large amounts of data, not real-time
  • Sequence checks verify data order is correct
  • Batch totals (hash total, financial total, record count) allow for error detection .

Online Real-time Processing Controls

  • Prompting verifies completeness
  • Closed-loop verification uses input data to verify related data

Processing Controls

  • Data matching verifies data consistency between different sources.
  • File labels ensure that updated files are used
  • Recal of batch totals are used to compare totals (financial, hash, and record count) to trailer records
  • Cross-footing is a calculation method to verify the accuracy of accounting records.
  • Zero-balance test verifies that credits and debits balance.
  • Write protection protects data from modification
  • Concurrent update controls prevent simultaneous data entry by different users.

Output Controls

  • User review of output involves manual review of outputs by users.
  • Reconciliation procedures compare system data with external data.
  • External data reconciliation compares system data with external data sets.
  • Data transmission controls are used to safeguard transmission of data.

Availability Controls

  • Preventive maintenance ensures system hardware and software are functioning correctly.
  • Fault tolerance ensures the system can continue operating even with hardware or software failures.
  • Data center location and design are critical for physical security.
  • Training for personnel is necessary for maintaining proper procedures.
  • Patch management and antivirus protection is critical

Disaster Recovery Plan (DRP)

  • Plans to restore IT functions when a disaster occurs
  • Three options: cold site, hot site, real-time mirroring

Business Continuity Plan (BCP)

  • Focuses on business process continuity
  • Periodic testing and revision of the BCP is critical

Revenue Cycle

  • Primary objective is to provide the right product at the right place at the right time.
  • Sales order entry involves taking customer orders, checking credit and inventory, and responding to inquiries.
  • Shipping includes picking and packing orders, and shipping goods.
  • Billing involves generating invoices.
  • Cash collection involves collecting payments.
