What is the difference between task and activity?

- Specific, discrete unit of work with a clear objective

- Structured, with a defined sequence of steps or stages

- Well-defined outcome or goal

- Limited duration

- Measurable progress

Activity

- Broader, less defined notion of work or engagement

- Can be structured or unstructured

- May or may not have a specific objective

- Not necessarily limited to a specific duration

- Progress may not be easily quantifiable

In summary, a task is a clearly defined, actionable unit of work with a specific goal, while an activity is a general term for work or engagement that may or may not have a clear objective or structure. Tasks are typically part of a larger activity or project, and contribute to the overall completion of the activity.
