Q. Why do I need project management?
One more way of asking this question is What if I do not bother with project management? The reality is all projects demand some extent of attention to make them happen. Even the secretary requires to deliberately plan to set aside some time to clean out that filing cabinet otherwise the job will never get done! Believe it or not faithfully the same holds true no matter what the size of the project. Certainly the bigger the project the more difficult it is to get it started.
But most projects as well require some degree of coordination of resources and unless this is carefully planned either things will be done in the wrong order or there will be constant conflict and crisis. Each of which will ultimately consume a lot more resources time and money than necessary.
