Which statement about incremental implementation strategies is true?

• A. They have a quicker return on investment.
• B. They are high risk, high anxiety.
• C. They require greater numbers of resources.
• D. They have higher training costs.

Answer: (D)

Incremental implementation means rolling out the system in smaller, staged steps rather than all at once. Each phase adds a defined set of functionalities, letting you test in real use, gather feedback, and adjust before the next piece is deployed. Because new features are introduced in multiple waves, staff often need training multiple times and training materials must be updated for each phase. That repeated training tends to increase overall training costs over the life of the project.

The other ideas don’t fit as well. A quicker return on investment is not the primary aim of incremental rollout—ROI tends to come in smaller, phase-by-phase gains rather than a big, immediate payoff. The approach also typically reduces risk and disruption, since problems can be contained within a phase rather than affecting the entire system at once, and it doesn’t usually require more upfront resources; rather, it spreads resource needs over time.
