What Is Project Management?
Project management is a set of activities which includes initiating, planning, executing, controlling and closing projects. It's a discipline that gives you principles, techniques, and tools to help you finish things on time and within budget.
The essential pillar of strength and support that holds up the entire project is the team of highly productive people who entirely devote themselves to it and make an all-out effort to get the job done.
Project management consists of a number of interlinking processes. A process is a series of actions performed by a team of people who work towards the same goal.
