Organisational structure

How you divide the work and join it back up, who reports to whom, who decides what, quietly shapes everything an organisation can do.

Organisational structure is the way an organisation arranges its roles, responsibilities, authority, and reporting relationships to coordinate its work. It is the formal skeleton of the organisation, determining how tasks are divided and how the divided parts are coordinated into a working whole.

Dividing and coordinating

Every organisation faces two basic problems: how to divide its work into manageable parts, and how to coordinate those parts so they pull together. Structure is the answer to both. It groups people and tasks, by function, product, region, or some mix, and it sets the lines of authority and communication that knit the groups back together. The fundamental tension is that the way work is divided creates boundaries that then must be bridged, and different structures strike that balance differently.

The main forms

Organisations adopt various structural forms, each with characteristic strengths and weaknesses. A functional structure groups people by specialism, finance, marketing, operations, gaining depth and efficiency but risking silos. A divisional structure groups by product, market, or region, gaining focus and responsiveness but duplicating functions. A matrix structure overlays two dimensions at once, gaining flexibility but creating the strain of dual reporting. The right form depends on the organisation's strategy, size, and environment, with no single structure best for all.

Structure follows strategy, and shapes it

The classic principle is that structure should follow strategy: the way an organisation is arranged should serve what it is trying to achieve. A firm pursuing efficiency in a stable market needs a different structure from one pursuing innovation in a turbulent one. But the relationship runs both ways: structure also shapes strategy, because the existing arrangement channels attention, information, and power, making some moves easy and others nearly impossible. An ill-fitting structure can quietly defeat a sound strategy.

Organisational structure is the formal architecture through which an organisation divides and coordinates its work, the skeleton on which everything else hangs. Its choice involves real trade-offs between specialisation and integration, efficiency and responsiveness, and it both serves and constrains strategy, which is why getting the structure right, fitting it to what the organisation is trying to do, is among the foundational decisions of organisational design.
