three-headed projects
The manwith3heads usually joins projects at the outset, when the nature of the strategic puzzle is being calibrated. The exit point depends on the brief and the shape of the overall team.
Typically, when working with agencies, handover is in the form of a strategic planning document or creative brief.
Whereas, when working direct with client organisations, the exit can be later, and involve assisting in the development of key market-facing deliverables, often in partnership with existing agencies.
