PM Essence

In keeping with our resolve to be of service to ALL sections of the Project Management community, we have pleasure in introducing this column. This section is intended to serve as the sounding board for the PMP / CAPM aspirants, as well as those doing other courses in Project Management, to interact with one another and get their doubts cleared. It is therefore expected to be run by the students themselves. Now and then members of the Faculty might chip in with some observations, but by and large it would be a column of the students, by the students and for the students of Project Management. We would now set the ball rolling with a few tips, as also touch upon aspects not exactly covered in the PMBOK. We would ask the student community to take it from there and go further forward. DID YOU KNOW?
