Which term describes gradually implementing a change in steps?

• A. phased change
• B. parallel method
• C. big bang
• D. remote working

Answer: (A)

Gradual implementation in steps is called a phased change. It means rolling out a change piece by piece, in stages, rather than all at once. This approach helps reduce risk because you can test each phase, gather feedback, and fix issues before the next part goes live. It also gives users time to adapt to the new system or process. In contrast, a parallel method runs the old and new systems side by side for a period, which is about comparison and verification rather than a staged rollout. A big bang approach switches everything over at once, increasing disruption and risk. Remote working describes where people operate from, not how a change is introduced.
