This question arrived in my inbox this morning and this is what I answered:
There is quite a big difference between ITIL and PMP and I suppose it really depends on your other skills and preferred job type to be able to answer your question.
PMP is a Project Management Methodology, which is mostly used in an IT environment, but is specifically created for the management of projects. PMP is a product of the Project Management Institute in the USA.
ITIL is a framework specifically created for the management of IT Services across the entire lifecyle. Most activities in the framework are combined in processes and because of this the framework has a focus on continual improvement of process, product, people and partner relations.
There are touchpoints between the project organisation (which may use PMP) and the strategic & operational side of an IT department (which may use ITIL ) and the two methodologies complement each other to enable the IT organisation to produce its IT Services to the best of its capabilities.
I hope this helps you to make the decision on what would be the better study path for you. Follow this link to read more about our eLearning pathway for the ITIL framework certification.
