Within the serial Workflow the Project Leader plans the resources with Workload. Then they change the status in “To proof”. It is now possible for the Team Leaders to work on the Team Planner and accept / deny the planning. When they are done, it goes back to the Project Leader for a last checking before he / she accept the changes (or deny and such give it back “To proof”).
Here it makes sense to work with email notifications by changing the status. But other
problems might occur: In the Workflow below you will see, Cerri.com recommends that still the Author / Project leader (or at least only one responsible e.g. via a role) is responsible for the status “To proof” and NOT all Team Leaders. This allows easier working. Otherwise it will in reality take too long until everybody have approved.
Again it might be helpful for the Team Leaders to meet in a weekly meeting and assign the resources.
Remark, the serial workflow is not recommended by Cerri.com (but possible in from a technical point of view).
