+
+The workflow can be summarized as follow:
+
+* Initiatives are submitted to CPE's project owner who will review them.
+* If the initiatives are deemed in scope for the CPE team, they will be accepted.
+* The CPE team will prioritize the initiatives against each other, leading to a
+  prioritized backlog of initiatives.
+* The ARC team will take the backlog in that order and for each initiative it will:
+
+  * Reach out to the CPE team and its communities (as needed) for input on potential
+    solution to implement the initiative
+  * Do the investigation/prototyping
+  * Report to the CPE team and its communities (as needed) its finding together
+    with a recommendation
+
+* The initiative will then be scheduled for the next prioritization meeting with
+  its stakeholders.
+* When the initiative is scheduled, the CPE team will take it and implement it
+  using the information, experiment and prototypes gathered and built by the ARC
+  team.
