An activity is a fundamental unit of work that must be performed over a specific period to complete
a project. In project management, activities are the individual tasks or components that make up the
project's work breakdown structure (WBS). Each activity is defined by its duration, required
resources, and dependencies on other activities.
Activities are the building blocks of a project schedule, and understanding them is crucial for
effective project planning, scheduling, and execution. By breaking down a project into activities,
project managers can better estimate time and resources, monitor progress, and make adjustments
as necessary to keep the project on track.
