# Activity log

> See a timestamped, auditable timeline of every action taken on a Plan, Scenario, or Event.

## Definition

The activity log provides a complete timeline of all actions taken on an object such as a Plan, Scenario, or Event. It automatically records changes such as creations and updates, making it easy to see who did what and when. This ensures transparency, accountability, and an auditable record of planning activities.

## Viewing logged activities

In each object drawer, open the **Activity Log** tab to see the history of actions related to that object.

The log automatically captures key events such as:

* **Object creation**, for example "Alice has created Event B".
* **Status changes**, for example "John updated Scenario A".
* Other edits and modifications to the object.

Each entry contains the **user's name**, the **timestamp**, and a **short description** of the action.

## Grouping and ordering

The log organizes entries by day, with the **most recent actions displayed at the top**. Within a day, actions appear in the order they occurred, making it easy to follow the sequence of updates.

## Example user journey

<Steps>
  <Step title="Create a scenario">
    You create a new scenario.
  </Step>

  <Step title="A teammate edits it">
    A teammate makes an edit to the same scenario.
  </Step>

  <Step title="Update an event">
    You update one of the scenario's events.
  </Step>

  <Step title="Open the Activity Log">
    Open the **Activity Log** tab. All three actions are listed, each with the user's name, a timestamp, and a short description.
  </Step>
</Steps>

This gives you a clear history of how the object evolved and who contributed.
