Which type of implementation would best describe executing a new initiative in phases?

The best description of executing a new initiative in phases is a phased implementation. This approach involves rolling out the new initiative step-by-step rather than all at once. By breaking the implementation into manageable phases, organizations can effectively manage resources, assess the impact of each phase before moving on to the next, and make adjustments as needed. This strategy allows for gradual integration of new systems or processes, making it easier to address any issues that arise during the implementation and to train staff effectively along the way.

In contrast, parallel implementation requires doing the old and new systems simultaneously, which can complicate the transition. Pilot implementation refers to testing the new initiative on a smaller scale before a full rollout, but it does not involve the phased approach across different segments. Full implementation would entail launching the entire initiative at once, which can be overwhelming and riskier without validation from earlier phases. Therefore, the phased implementation provides a structured methodology that aligns well with gradual change management.
