What characterizes a deterministic schedule?

A deterministic schedule is characterized by predictability, where all durations are fixed and do not allow for variability. This type of schedule assumes that each task will take a set amount of time to complete, leading to a clear and straightforward timeline for project completion. In deterministic scheduling, there is no uncertainty regarding the duration of activities; each task is defined with specific start and finish times based on the established plan.

The focus on fixed durations means that the schedule can be relied upon to provide an accurate representation of the project's timeline, making it easier for project managers to plan resources and allocate time accordingly. This approach is often contrasted with stochastic or probabilistic scheduling methods, where durations might vary and statistical methods are employed to plan for uncertainties.

The other options involve elements that would be more commonly associated with different types of scheduling methodologies. For example, incorporating estimated costs and risks or evaluating multiple scenarios typically aligns with more flexible and risk-adjusted planning techniques rather than the rigid structure of a deterministic approach.
