Types of Organisational Structure
Seven Types of Organisational Structure
| Type | Core idea |
|---|---|
| Simple | Small firm, centralised authority in one person, few rules, flat hierarchy |
| Functional | Grouping by similar work specialties |
| Divisional | Grouping by similarity of purpose (products, services, customers, regions) |
| Matrix | Grid by functions and divisions; two chains of command |
| Team-based | Cross-functional teams to solve problems and improve horizontal relations |
| Network | Central core linked to outside firms by computer connections |
| Modular | Outsourcing pieces of a product to outside firms |
Also: tall and flat structures, covered in the next article.
Most schools use a recognisable kind of structure but never name it explicitly. Naming the type makes it easier to see the trade-offs and consider alternatives. The seven main types from the management literature each have their fit, and some fit schools better than others.
Simple structure
Often found in a firm’s early, entrepreneurial stages. Authority is centralised in a single person. Few rules, flat hierarchy, and low work specialisation.
The simplest structure. One person at the top, everyone else reports to her, few formal procedures.
In a school: a small private school in its early years, with one principal, six or seven teachers, and minimal administration. The principal does most of the management work. Decisions are quick. Communication is direct.
Strengths: speed, low overhead, clear accountability. Weaknesses: bottlenecks at the leader, limited growth potential, brittle if the leader is absent.
Most schools outgrow the simple structure within a few years of opening. As staff grows, the principal cannot manage everyone directly.
Functional structure
Similar occupational specialties are put together in formal groups. A quite commonplace structure, seen in all kinds of organisations, for-profit and non-profit.
The most common school structure. Staff are grouped by what they do.
A typical school’s functional structure:
- Academic. Teachers, grouped by section or department.
- Administration. Finance, admissions, HR, IT.
- Operations. Maintenance, transport, security, catering.
- Student services. Counselling, library, sports, extracurricular.
Each function has its own head, reporting to the principal or a deputy.
Strengths: clear expertise within each function, efficient resource use, predictable career paths within a function. Weaknesses: silos between functions, communication gaps across functions, slow decisions that need cross-functional input.
Most schools use functional structure as the dominant form. Adding cross-functional teams (covered below) can mitigate the silo weakness.
Divisional structure
Diverse occupational specialties are put together in formal groups by similar products or services, customers or clients, or geographic regions.
Grouping by purpose rather than by specialty.
In a school: a school chain with multiple campuses might organise by campus. Each campus has its own academic, admin, and operations functions. The campus principals report to a CEO or to a board.
Or: a school might organise by educational stage. Primary, Middle, and Secondary each have their own staff, head, and resources, with the principal at the top.
Strengths: each division focuses on its purpose; faster local decisions; clearer accountability for outcomes. Weaknesses: duplicated resources across divisions; loss of school-wide expertise sharing; possible competition between divisions.
Large school groups commonly use divisional structure. Single-campus schools rarely need it.
Matrix structure
An organisation combines functional and divisional chains of command in a grid so that there are two command structures: vertical and horizontal. Used for projects.
The most complex of the common structures. Each staff member reports to two managers: a functional manager (her specialty) and a project or divisional manager (her current assignment).
In a school: a teacher might report to the head of mathematics (functional) and to the grade-5 coordinator (sectional). Both have authority over her work, in different ways.
Strengths: combines depth of expertise with focus on outcomes; flexible deployment of staff. Weaknesses: dual reporting produces conflict; communication overhead is high; accountability can blur.
Matrix structures are common in large project-based organisations (consulting firms, large engineering firms). Schools rarely use full matrix, but elements of it appear when a teacher serves in multiple cross-cutting roles.
Team-based structure
Teams or workgroups, either temporary or permanent, are used to improve horizontal relations and solve problems throughout the organisation. Cross-functional teams.
Structure organised around cross-functional teams that handle specific problems or projects.
In a school: a curriculum review team that includes teachers from different subjects, an admin staff member, and a parent representative. A discipline review team. A campus expansion team. Each team has a defined mission and life.
Strengths: breaks down silos; speeds up problem solving; develops cross-functional understanding. Weaknesses: team membership distracts from primary functions; can produce conflict between team and functional manager.
Many schools use team-based elements on top of a functional structure. The combination works well when teams have clear mandates and time-limited assignments.
Network structure
The organisation has a central core that is linked to outside independent firms by computer connections, and operates as if all were a single organisation.
A core organisation with deep partnerships with external firms.
In a school: a small school that contracts out catering, transport, IT, and even some teaching to specialist providers. The core school is small; the network is large. The “school” experience for students includes services from many organisations linked together.
Strengths: low fixed costs; flexibility to scale partners up or down; access to specialist expertise. Weaknesses: dependence on external partners; less control over quality; potential for things to fall between organisations.
Network structures are growing in education. Many newer schools deliberately keep their core staff small and contract out specialised services.
Modular structure
Differs from the previous in that it outsources certain pieces of a product rather than outsourcing certain processes (such as human resources or warehousing) of an organisation.
Outsourcing specific outputs rather than internal processes.
In a school: the school might outsource the entire science curriculum to a specialist provider who handles teaching, labs, and assessment. The school remains the school but a specific module of its work is done by an outside organisation.
Strengths: access to deep expertise in specific areas; clear contractual outputs; risk transfer. Weaknesses: integration with the rest of the school can be weak; the outsourced module may not align with the school’s broader culture.
Modular structures are less common in schools than network structures. They appear in vocational training and in specialised programmes.
Which type fits a school
Most schools end up with a hybrid:
- Functional structure as the base. Teachers in departments and sections.
- Divisional elements if multi-campus. Each campus operates somewhat independently.
- Team-based elements for specific initiatives. Cross-functional teams for projects.
- Network or modular elements for non-core services. Catering, transport, IT, sometimes specialist programmes.
A school head should know which type is dominant in her school and why. The dominant type shapes how the school can adapt to change. A pure functional structure adapts slowly; adding team-based elements speeds up adaptation.
Simple, Functional, Divisional, Matrix, Team-based, Network, Modular.
- Simple. Small, centralised, few rules. Early-stage schools.
- Functional. Grouped by specialty (subjects, departments). Most common school structure.
- Divisional. Grouped by purpose (campuses, sections). Multi-campus school groups.
- Matrix. Grid with two chains of command. Rare in pure form in schools.
- Team-based. Cross-functional teams for problems. Common as an add-on.
- Network. Core organisation with deep external partnerships. Growing.
- Modular. Outsourcing specific outputs. Less common in schools.
Most schools use a hybrid: functional as the base, with divisional, team-based, network, or modular elements added.
