We probably need more information to understand exactly what you want to know.
During my corporate career, a deviation typically meant something unexpected happened that we have to accept in order to continue business. Therefore it is always "unplanned". We tried very hard to push everything to follow the change management process and not accepting deviation. In general, regardless what triggered the deviation, you should restrict/ identify the population, the short action plan to use that population, and the criteria to end the deviation.
Our design engineers used to push for "forever deviation" to avoid going the change process. That may be the "planned deviation" in your case. We killed that as much as we could, because that became a traceability nightmare.
As that blog post indicates if you are in an FDA regulated industry the terminology makes a difference.
