What is a Functional Organization?
In a functional organization, staff are grouped by specialty — engineering, marketing, finance — and report to functional managers who hold the power. Projects run inside or across departments, and the "project manager," if one exists, is a coordinator or expediter with little or no formal authority.
Exam signature: the PM must ask functional managers for everything — people, money, decisions. Strong for deep expertise and clear careers; weak for cross-functional speed.
Worked example
At a machine-tool manufacturer, a new-product effort needs two designers and a test rig. The project coordinator can't assign anyone; she petitions the head of design, who lends the designers "when the department can spare them." The launch slips a quarter — not from technical trouble, but because nobody with project goals held resource authority.
