Changes in Organisational Structures
This topic is assessed in IBDP Business Management at Higher Level (HL) only.
Organisations rarely remain structurally static. As strategy, scale, technology and competitive pressures evolve, businesses restructure — changing how authority is distributed, how many management layers exist and how people and functions are grouped. Understanding the main types of structural change, and their consequences, is an important HL competence.
Delayering
Delayering is the removal of one or more management layers from an organisational hierarchy — making the structure flatter. Typical triggers include: cost reduction pressure (management layers are expensive); the adoption of digital management information systems that reduce the need for middle managers to filter and relay information; a strategic shift toward greater employee autonomy; or a post-acquisition reorganisation where duplicate management layers across two merged organisations are consolidated.
When Meridian Logistics restructured from five management tiers to three, it eliminated the regional director layer. This freed £1.4 million in annual salary costs, shortened the communication chain between the CEO and site managers, and required site managers to take on broader responsibility. The risk: area managers whose span of control widened from three sites to seven needed significant support to manage the transition effectively.
| Potential benefits of delayering | Potential risks of delayering |
|---|---|
| Reduced management cost | Remaining managers overstretched by wider spans |
| Faster communication and decisions | Loss of experienced managers and their knowledge |
| Greater employee autonomy and motivation | Reduced career progression opportunities |
| Clearer accountability lines | Quality and supervision may suffer during transition |
Restructuring to a Matrix Structure
Restructuring may involve changing how people are grouped — for example, moving from a functional structure to a matrix structure. A matrix structure combines two organisational dimensions simultaneously, typically function and project. Employees report to both a functional manager (e.g. head of engineering) and a project or product manager. This enables specialist skills to be deployed across multiple projects whilst maintaining functional depth.
Restructuring to a Divisional Structure
A business may move from a functional structure to a divisional structure — organising around products, services or geographic regions rather than functional specialisms. Each division becomes a semi-autonomous business unit with its own P&L and all the functional support (marketing, finance, HR) it needs. This is common when a company diversifies into multiple product lines that are sufficiently different to require dedicated management focus rather than shared functional resources.
Why Restructuring is Challenging
Structural change disrupts established working relationships, reporting lines and informal networks. Employees who lose status, seniority or familiar colleagues through restructuring tend to resist — even if the new structure is objectively better suited to the organisation's strategy. The period immediately following restructuring typically involves reduced productivity, increased staff turnover and cultural uncertainty before the benefits of the new structure are realised. Effective change management — clear communication, consultation and support — significantly affects the speed and quality of the transition.
