Direct Changeover

  • The old system is immediately replaced by the new system.
  • This method is used when quick implementation is essential.

Parallel Running

  • Both the old and new systems operate simultaneously for a period before the old system is fully phased out.
  • This approach is used to ensure a smooth transition with minimal risk.

Pilot Running

  • The new system is deployed in a small, controlled environment before full-scale implementation.
  • This strategy is used to test the new system in a real-world setting.

Phased Implementation

  • The new system is introduced in stages, with each stage replacing a portion of the old system.
  • This method is used to ensure a gradual transition, minimizing disruption.

FAQs on Systems Life Cycle: Implementation - IGCSE Information and Communication Technology Preparation - Year 11

1. What are the different methods of implementing a system in the systems life cycle?
Ans. The different methods of implementing a system in the systems life cycle include parallel run, direct changeover, and system implementation in stages.
2. What is parallel run in system implementation?
Ans. Parallel run is a method of system implementation where the new system runs alongside the old system for a period of time to ensure that it is working correctly before fully transitioning to the new system.
3. What is direct changeover in system implementation?
Ans. Direct changeover is a method of system implementation where the old system is completely replaced by the new system on a specific date, without running them simultaneously.
4. What is system implementation in stages?
Ans. System implementation in stages is a method of implementing a system gradually, in phases, rather than all at once, allowing for easier transition and troubleshooting.
5. Which implementation method is most suitable for a large organization with complex systems?
Ans. System implementation in stages is typically more suitable for a large organization with complex systems, as it allows for a smoother transition and reduces the risk of disruptions in operations.
