The implementation approach that proceeds in stages with two weeks between each installation is called what?

• A. Phased installation
• B. Parallel installation
• C. Big bang installation
• D. Risky installation

Answer: (A)

A phased installation rolls out the system in stages, with defined intervals between steps. The two-week gap between installations gives time to test each phase, train users, address issues, and confirm data integrity and workflow changes before expanding to the next area. This approach reduces disruption, allows lessons learned to inform the next rollout, and lowers overall risk compared with deploying everything at once. By contrast, parallel installation would require running old and new systems together for an extended period, which can be resource-intensive and lead to data reconciliation challenges, while a big-bang approach implements everything at once and carries a much higher risk of downtime and user disruption.
