During the planning phase of a UKG implementation, one of the earliest and most important decisions is how to structure your go-live rollout strategy. Organizations typically choose between two contrasting methodologies, Big Bang or Phased. Both can lead to successful outcomes, but the journey and plan to get there look very different. Understanding these differences can help customers and consultants align expectations, mitigate risks, and design a rollout that supports long-term adoption.

A Big Bang HCM implementation means launching all selected UKG modules at the same time, including:
Timekeeping, Scheduling, HR, Payroll.
