The PMBOK 4th edition, page 73, mentions that, thanks to the develop project charter process, a partnership is born between executor (performing organization) and receiver (requesting organization). This implies that several people – a team in other words – are necessary for project management to be viable, at least from the project execution point of view. Apparently, a one person team executor is not OK under the PMBOK.
Here is the PMBOK quote:
Develop Project Charter is the process of developing a document that formally authorizes a project or a phase and documenting initial requirements that satisfy the stakeholders' needs and expectations. It establishes a partnership between the performing organization and the requesting organization (or customer, in the case of external projects).
Let's say that the project's product (it's final result) is nothing but a researched SCHOLAR book with such vast a scope that not even an awesome methodology such as KATIE TURABIAN's will be capable of managing the time I would need to juggle work, family, career and personal time.
Bottom line: the result is indeed small (a book) but the result's scope is so large (book volumes) that I would need to treat it as a project under the PMBOK. It's not a book you can finish in less than 10-15 years.
However, as with most books, it is best they are researched, argued, drafted and proofed by a single person, maybe only edited, published and marketed by a third party.
If you accept this, can I refrain from searching for a sponsor and forming a PM execution team?
You can imagine the project's initiation charter will have no signatures since it is only towards my own self that a duty will emerge in the sense of producing the book, regardless of the fact that I also need to have in consideration the project's stakeholder needs.
