An Essentials Plus Approval process allows for notifications and control over your deployments through a Work Items Pipeline. Receive notifications on the deployments set to the stages of the Work Items. Set approvers where you can have a majority rule on the approval of the deployment.
Setup Approval Process in your instance.
Step 1) Ensure Work Items is enabled in your team settings. Set the pipeline you wish to have an approval process assigned too.
From your Pipeline tab select the pipeline you would like to add approvers to (you can set a variation of the amount of approvers and what environments you want approval of the deployment).
If the setting for "Required approving reviews" is set to '0', you can assign WorkItems to any number of approvers.
Step 2) Create a Work Item and set the approval process check marks.
a). In order to be an "approver" the user must have the Owner or Team Lead role assigned
b). The approver grants approval for the deployment process originating FROM an organization.
Step 3) Once you create a Work Item you will now need to select the approvers. An email will then be sent to the user selected.
