What is planning and what do planners do?

[Melissa Clark]

I'm sure many of you have been in this position before but I need some help explaining a little about planning to those who are new to the concept. I have my own ideas (not to mention the classic definitions, white papers, etc.) but if you could help out by sharing your own thoughts on the following questions, I'd greatly appreciate it.

1. What is planning?
2. What do planners do?
3. What don't planners do?
4. How can planning help?
