Experiment Statuses - Experro

Every experiment carries a status that tells you whether it is running, waiting to run, or finished. Status also controls what you can do to the experiment — a published experiment cannot be edited or deleted, but it can be paused.

Status Definitions

Status	What it means	How it gets here
Draft	Saved but never started.	You click Save without starting, or you pause a running experiment.
Scheduled	Started, but the start date is still in the future.	You click Start Experiment with a future start date.
Published	Live and collecting data.	The start date arrives, or you start an experiment dated today.
Completed	Finished collecting data.	The end date arrives, or you end it manually.
Paused	Temporarily stopped.	You click Pause on a scheduled or published experiment.

How Statuses Change

A scheduled experiment becomes published automatically. Experro checks for due experiments every three minutes. Resuming a paused experiment sends it back to Published if the end date is still in the future. If the end date has already passed, it moves straight to Completed.

Key Considerations

Published, paused, and completed experiments are read-only. Clone the experiment to make changes.
Published and paused experiments cannot be deleted. Pause first, or end the experiment.
Cloning always produces a draft, with the start and end dates cleared.

A draft whose end date has already passed cannot be started. Update the end date to a future date first, or the system rejects the start.

Because the scheduler runs every three minutes, an experiment whose start and end dates are less than three minutes apart may never publish. Widen the window and start it again.
