The term "Activity Duration" refers to the amount of time it takes to complete a specific activity within a project or process. It is a critical component of project scheduling and planning, as it helps project managers and teams estimate how long each activity will take to complete.

The duration of an activity is typically estimated based on historical data, expert judgment, or previous experience with similar activities. It's important to make accurate duration estimates to ensure that the project stays on track. Use your company’s know-how as the basis when assigning duration to an activity, and these durations must be updated occasionally, depending on the dynamics of the business the company is operating in.
