Let’s define the PM System by “a set of method(s), templates, bests practices, tools, processes and software”. How does that sound ?
A customer once told us “it’s the oil you put in the machine to make it run smoothly”
Ain’t that right? It’s exactly what it is. Say your project is a locomotive. You’re the guy or the girl with coal stains and a big smile on your face. There’s a long trip ahead, if you don’t oil it up you’re gonna get stuck.
The Project Management Method will provide you with the “how to”
The Project Management Processes will provide you with the “who and when?”
The Project Management Software is supposed to make the above easier. We say “supposed” on purpose, because sometimes it is just an additional pain in the neck.
