The implementation team has determined that the conversion to the new system will occur department by department, with two weeks in between each installation. This is known as:

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

Answer: (A)

This pattern is a phased installation. By rolling out the new system department by department with a gap between installations, the project can validate each step, refine workflows, and address any issues in a contained scope before the next group goes live. The two-week interval gives time for training, testing, data migration checks, and user support, which helps minimize disruption and reduce risk compared with trying to switch everyone over at once. In contrast, a parallel approach would keep the old system running while the new one is introduced, allowing comparison and fallback; a big bang approach would switch all departments to the new system in a single, immediate transition, which poses a higher risk of widespread problems. The term for the described method aligns with phased installation configuration.
