7th-ever-blog-post. It's from Max Wideman, who is never wrong.
"...The most useful first step in managing a project of any size is to start by breaking down its scope, as defined above, according to a well-established and logical sequence. This sequence looks something like this: First according to geographically discrete components, if this is applicable; Second according to time based phases and stages, where each has a clear deliverable; Third according to intermediate or final major deliverables; Fourth according to discrete structural, process, system or device components. Finally, into deliverable elements that can be associated with distinctive types of people-skills or resources."
I can look at this years late and say; Yes, this makes sense to me.
