Value Drivers

  • Improper components detected and removed from production
  • New system operating as intended and supporting the business processes
  Risk Drivers
  • Old systems not available when needed
  • Unreliable system and conversion results
  • Subsequent processing interruptions
  • Data integrity issues

  1. Define a data conversion and infrastructure migration plan. Consider, for example, hardware, networks, operating systems, software, transaction data, master files, backups and archives, interfaces with other systems (both internal and external), procedures and system documentation, in the development of the plan.
  2. Ensure that the data conversion plan incorporates methods for collecting, converting and verifying data to be converted, and identifying and resolving any errors found during conversion. This includes comparing the original and converted data for completeness and integrity.
  3. Confirm that the data conversion plan does not require changes in data values unless absolutely necessary for business reasons. Document changes made to data values, and secure approval from the business process data owner.
  4. Consider real-time disaster recovery, business continuity planning, and reversion in the data conversion and infrastructure migration plan where risk management, business needs, or regulatory/compliance requirements demand.
  5. Co-ordinate and verify the timing and completeness of the conversion cutover so there is a smooth, continuous transition with no loss of transactions. Where necessary, in the absence of any other alternative, freeze live operations.
  6. Ensure that there is a backup of all systems and data taken at the point prior to conversion, audit trails are maintained to enable the conversion to be retraced, and there is a fallback and recovery plan in case the conversion fails. Ensure that retention of backup and archived data conforms to business needs and regulatory or compliance requirements.
