What is Maker-Checker?

Transaction Lifecycle

  1. Initiation (Maker)
    • Create transaction
    • Submit for approval
    • Transaction status: Pending
  2. Review (Checker)
    • Examine transaction details
    • Options:
      • Approve transaction
      • Decline transaction
  3. Outcome
    • Approved: Transaction processed
    • Declined: Transaction rejected
    • Pending: Awaiting review

​
Best Practices

  1. Segregation of Duties
    • Makers cannot approve their own transactions
    • Checkers must be different from makers
  2. Security Measures
    • Implement multi-factor authentication
    • Maintain comprehensive audit logs
    • Regularly review role assignments

​
Troubleshooting

  • Transaction Stuck: Contact system administrator
  • Permission Issues: Review role configuration
  • Approval Delays: Check checker availability
