In my opinion it is good. I've been working as a PM n doing reasonably well.. but on taking the PMP course, I discovered loads of information on how U can better do the job. That there is more to PM than the traditional ways adopted.
Especially since its done in a structured n organised manner and in international terms which ppl fr all over can understand and identify with. Having the PMP will empower U to take on PM jobs more confidently. Of cos experience also counts.
I am curious how these so called PMPs got their certificate if they cant even vouch for some basic experience. All depends on individual dedication.
I wud say go for it. Good luck.
