About the Lifecycle of a Study

The lifecycle of a study has the following states and transitions:


	A study owner requests approval, including specifying one or more approver study members who have review rights. For more information, see Requesting Study Approval.
	A specified approver member of the study reviews the study and approves it or rejects it for further edits. For more information, see Approving a Study.
	A study owner activates the approved study. For more information, see Activating a Study.
	A study owner completes the active study. For more information, see Completing a Study. If the completed study requires additional results later, a study owner who requested finalization or member with review rights can return it to the active state.
	A study member with review rights finalizes the study. For more information, see Finalizing a Study. If the finalized study requires additional work, a study owner can return it to the active state.
	A study owner rejects an approved study, returning it to the unapproved state. For more information, see Withdrawing a Study.
	A study owner pauses an active study, returning it to the inactive state. If an inactive study is ready to be worked on again, a study owner can reactivate it. For more information, see Reactivating an Inactive Study.
	If an active study requires a change in its definition, a study owner can reject it so that it returns to the unapproved state. For more information, see Updating an Active Study.
	If an inactive study requires a change in its definition, a study owner can reject it so that it returns to the unapproved state. For more information, see Withdrawing a Study.
