Implementation Methods in IT Systems

Which implementation method runs both the old and new systems simultaneously?

• A. Pilot implementation

• B. Direct changeover

• C. Parallel running

• D. Phased implementation

What is a key advantage of direct changeover?

• A. It is the least risky implementation method.

• B. It ensures consistent data usage by using one system at a time.

• C. It allows errors to be fixed before full deployment.

• D. It is a slower method to reduce risk.

Which of the following is a disadvantage of phased implementation?

• A. The new system is not beta-tested by a group of users.

• B. Both systems must run simultaneously for an extended period.

• C. Users might be confused about which system to use for specific tasks.

• D. It does not allow for incremental training.

In pilot implementation, what role does the pilot group play?

• A. They serve as a backup for the new system.

• B. They use the new system exclusively to ensure compatibility with the old system.

• C. They beta-test the new system and may train other users.

• D. They identify all data inconsistencies in the old system.

Why is parallel running considered less risky?

• A. Errors in the new system only affect the pilot group.

• B. Both systems do not require compatibility for data sharing.

• C. The old system remains operational if the new system fails.

• D. It allows for the quickest transition between systems.

What is a disadvantage of direct changeover?

• A. Users may experience delays during implementation.

• B. There is a high risk of system failure with no fallback.

• C. Errors are limited to specific phases rather than the entire system.

• D. The organisation needs to install additional hardware for the transition.

Which implementation method introduces parts of the new system incrementally?

• A. Phased implementation

• B. Pilot implementation

• C. Parallel running

• D. Direct changeover

What is a disadvantage of pilot implementation?

• A. Errors affect the entire organisation during the transition.

• B. The rest of the organisation must wait until the pilot is completed.

• C. Users may need additional hardware for data duplication.

• D. It does not allow for real-world feedback.

What is one advantage of phased implementation?

• A. It allows users to be trained on all system functionalities at once.

• B. It eliminates the need for compatibility between old and new systems.

• C. Errors affect only the implemented phase, not the whole system.

• D. It allows the fastest transition between systems.

Why might parallel running require additional staffing costs?

• A. Errors found by users in the pilot group require manual correction.

• B. Both systems must share compatible data formats.

• C. Duplication of data input across both systems increases workload.

• D. Users may need extensive training before using the new system.
