There are 4 types of assigment family:
* The accounting team has assignment like: accounting/manager or accounting/agent
  They can see all invoices, but can not modify the automated ledger
* The sale team has assignment like: sale/manager or sale/agent
* A virtual master customer has an assignment like:
    function/customer
    destination_project/THE_PREFERED_DEFAULT_PROJECT
  He can request instance trees.
  He can see all the nodes on the virtual master.
* The virtual master manager has assignment like:
    function/production/manager
    destination_project/THE_PROJECT
    or
    function/production/agent
    destination_project/THE_PROJECT
  He is responsible to create the compute node and ensure the quality
  of the service provided on it (so, he manages the related crm).

Worklist must be usable, to quickly allow any user to know what is
expected from him in the system.
