Fractional project manager
In short. A fractional project manager is an experienced project manager who works for a business part-time, for example one or two days a week, rather than as a full-time employee. They plan and run projects, manage risks and changes and keep work on track, for a fraction of the time and commitment of a permanent hire.

Project management, as the Association for Project Management defines it, is applying processes, methods, skills and experience to achieve specific objectives within an agreed timescale and budget. A fractional project manager brings that discipline on a part-time basis.
The arrangement suits businesses that have important projects but not enough of them to keep a senior project manager busy full time: a system replacement, a move to new premises, a product launch, or several smaller projects that keep colliding.
The value is less in the hours than in ownership. Someone is responsible for the plan, for spotting risks early, for managing changes and for closing the project properly, instead of that work landing on a founder or being shared by nobody.
It works best with a clear scope and a named decision-maker on the business side. A fractional project manager can run the project; they cannot make decisions nobody in the business is willing to make.
Questions people ask
When does a business need a fractional project manager?
When projects matter but there is not enough of them for a full-time role, when the founder has become the project manager by default, or when projects keep running late because nobody owns the whole of them.
What is the difference between a fractional and an interim project manager?
An interim usually works full time for a fixed period, often to cover a gap. A fractional works part time on an ongoing basis.
