The certification does not make you a better project manager.
But it provides you the base to become a better project manager.
And this can only happen if you use and tailor the knowledge you have collected properly to your own environment.
Different projects will have different approach although the basis will remain the same. It is up to the project manager to wisely identify the best way to manage, monitor and/or correct the project. As it is with people. Different people requires different communication style or intervention approach. A leader should be able to get close to the team he or she coaches with variety of styles and skills.
Any certifications or degrees provides us the knowledge.
It is up to us how we use the knowledge for our purposes and improvements.
You are only as good as the knowledge that you use correctly.
