Hi Alan, you may be pleased to know that this is quite a common quandary and is one that comes up many times, so you're not alone in your considerations.
Arras People put together a very helpful overview of each of the qualification programmes Link Removed
, and in terms of the question about whether to do Prince2, or APM qualifications or both, Link Removed
from Arras People may be of use, along with the document Link Removed
by Hemsley Fraser.
There is also a route to APMP for PRINCE2 practitioners which recognises prior learning. You can find out more about that on Link Removed
Best of luck with your career progression, and any queries, do get in touch.
Product Development Manager, APM
