Organisational Structure

Structure defines how activities are divided, coordinated, and controlled within an organisation. The structure must support the strategy — "structure follows strategy" (Chandler, 1962).

StructureDescriptionAdvantagesDisadvantagesBest suited to
Functional Organised by business function: marketing, finance, operations, HR, IT. Each function headed by a specialist manager reporting to the CEO. Clear specialisation and expertise, economies of scale within functions, clear career paths, simple and efficient for single-product businesses Functional silos (poor cross-functional coordination), slow response to change, difficult to allocate accountability for products/markets, CEO becomes a bottleneck Small-medium firms, single-product, stable environments
Divisional Organised by product, geographic region, or customer segment. Each division operates semi-autonomously with its own functional departments. Clear accountability per division, responsive to local/product-specific needs, facilitates diversification, easier performance measurement (profit centres/investment centres) Duplication of functions across divisions (higher cost), potential for divisional rivalry, loss of central control, difficult to share resources/knowledge across divisions Large, diversified, or geographically dispersed firms
Matrix Dual reporting — employees report to both a functional manager and a project/product/regional manager. Combines functional expertise with project/product focus. Combines functional specialisation with product/project focus, facilitates cross-functional collaboration, flexible resource allocation, develops multi-skilled managers Dual authority creates confusion and conflict, complex decision-making, time-consuming (many meetings), power struggles between functional and project managers, costly Complex environments, project-based work, multinational organisations needing both functional and geographic focus
Network (virtual) A core organisation that outsources many functions to external partners. Coordinated through contracts, technology, and relationship management rather than hierarchy. Highly flexible, low fixed costs, access to best-in-class capabilities from specialist partners, scalable, rapid response to change Reduced control over quality and delivery, dependency on partners, coordination challenges, risk of knowledge loss, potential for partner opportunism Dynamic environments, technology firms, fashion/media, firms with a strong core competence but limited internal capacity

McKinsey 7S Framework

The McKinsey 7S model (Peters and Waterman, 1982) identifies seven interdependent elements that must be aligned for an organisation to implement strategy effectively. A change in one element requires adjustments in the others.

Three "hard" elements (tangible, easier to define and manage):

  • Strategy: The plan for achieving competitive advantage — the chosen direction and positioning
  • Structure: The organisational structure — how the firm is organised, reporting lines, division of responsibilities
  • Systems: The processes, procedures, and systems that support daily activities — IT systems, financial reporting, HR processes, quality systems, performance management

Four "soft" elements (intangible, harder to define and change, but often more critical):

  • Shared values: The core values, beliefs, and purpose of the organisation — its culture and identity. Located at the centre of the model because they influence all other elements.
  • Skills: The distinctive capabilities and competences of the organisation and its people
  • Staff: The people — numbers, types, development, and how they are recruited, trained, motivated, and retained
  • Style: The leadership and management style — how managers behave, how decisions are made, how communication flows

Application: When implementing a new strategy, use 7S to identify which elements need to change and whether they are aligned. Misalignment (e.g., a new innovation strategy with a bureaucratic structure, risk-averse culture, and systems designed for efficiency not creativity) will lead to implementation failure. The model highlights that strategy alone is insufficient — all seven elements must support it.

Managing Strategic Change

Strategic change is difficult because it involves altering established patterns of behaviour, challenging the status quo, and overcoming resistance.

Lewin's Three-Stage Model of Change

Kurt Lewin (1947) proposed that successful change involves three stages:

1. Unfreeze:

  • Create awareness that the current state is unacceptable and that change is necessary
  • Overcome complacency and resistance — people must recognise the need for change before they will accept it
  • Tactics: communicate the business case for change, highlight the dangers of NOT changing (burning platform), involve people in diagnosis, challenge existing assumptions, create a sense of urgency

2. Change (transition):

  • Implement the new strategy, processes, structures, or behaviours
  • People move from the old way to the new way — this is the most uncertain and uncomfortable phase
  • Tactics: clear communication of the vision and plan, training and support, quick wins (visible early successes to build momentum), empowerment, remove obstacles

3. Refreeze:

  • Embed the changes into the organisation's culture, systems, and processes so they become the new "normal"
  • Without refreezing, people revert to old behaviours
  • Tactics: align reward systems with new behaviours, update policies and procedures, celebrate and reinforce success, hire/promote people who embody the change, monitor and adjust

Lewin's force field analysis: Change is driven by driving forces (pushing for change — competitive pressure, new technology, customer demand) and resisted by restraining forces (pushing against change — fear, habit, vested interests, cost). Change occurs when driving forces exceed restraining forces. Management can either strengthen driving forces or weaken restraining forces (often more effective and less confrontational).

Kotter's Eight Steps for Leading Change

John Kotter (1996) identified eight sequential steps for leading successful organisational change:

  1. Create a sense of urgency: Help people see WHY change is needed. Highlight threats, identify opportunities, challenge complacency. Without urgency, change initiatives stall.
  2. Build a guiding coalition: Assemble a group with enough power, expertise, and credibility to lead the change. Change cannot be driven by one person — it needs a team of influential leaders.
  3. Form a strategic vision and initiatives: Develop a clear, compelling vision of what the changed organisation will look like, and create strategies to achieve it. The vision must be communicable in under five minutes.
  4. Enlist a volunteer army: Communicate the vision broadly and repeatedly through multiple channels. Win hearts and minds — people must understand and embrace the vision.
  5. Enable action by removing barriers: Remove obstacles that block the change — restructure, change systems, remove individuals who undermine the change, empower people to act on the vision.
  6. Generate short-term wins: Plan for and create visible, unambiguous early successes. Quick wins build credibility, motivate the team, and silence critics. Celebrate and publicise them.
  7. Sustain acceleration: Use the credibility from early wins to tackle bigger, harder changes. Do not declare victory too soon — consolidate gains and keep pushing. Hire, promote, and develop people who support the change.
  8. Institute change: Anchor the new approaches in the culture. Make explicit connections between the new behaviours and organisational success. Ensure leadership development and succession reinforce the change.

Common reasons for change failure (Kotter): Insufficient urgency (step 1), lack of a powerful coalition (step 2), no clear vision (step 3), under-communicating the vision (step 4), failure to remove obstacles (step 5), no short-term wins (step 6), declaring victory too soon (step 7), failing to embed in culture (step 8).

Culture and Strategy

Handy's four cultural types (Harrison/Handy):

CultureCharacteristicsStrengthsWeaknesses
Power culture (web)Central figure/small group controls everything. Few rules — decisions depend on the power holder's judgement. Common in entrepreneurial start-ups.Quick decisions, responsive, strong leadershipOver-dependent on one person, may lack checks/balances, succession risk, may not scale
Role culture (temple)Bureaucratic — defined roles, rules, procedures, hierarchies. People operate within their job description. Common in large, stable organisations (government, banks).Stable, predictable, clear accountability, efficient for routine tasksSlow to change, inflexible, stifles innovation, people become narrow specialists
Task culture (net)Focus on getting the job done — project teams, matrix structures, expertise-driven. Authority comes from knowledge, not position. Common in consultancies, technology firms.Flexible, collaborative, results-oriented, adaptable, empowers expertsDifficult to control, resource conflicts between projects, may lack long-term stability
Person culture (cluster)The individual is the central point — the organisation exists to serve the individuals within it. Minimal structure. Common in partnerships (law firms, medical practices, academia).Maximum individual autonomy, attracts talented professionalsDifficult to manage or direct, little organisational loyalty, hard to implement collective strategy

Johnson's cultural web:

A tool for analysing the taken-for-granted assumptions (the paradigm) that shape an organisation's culture. Six elements surround the paradigm:

  1. Stories: Narratives about the organisation's history — what people talk about, who are the heroes and villains, what events are celebrated or condemned
  2. Symbols: Visual representations of culture — logos, offices, dress codes, language, job titles, company cars, parking spaces
  3. Power structures: Who holds the real power — which groups or individuals are most influential? Their assumptions shape the paradigm.
  4. Organisational structures: Formal hierarchy and informal networks — how work is organised, who reports to whom, who collaborates with whom
  5. Control systems: What gets measured, monitored, and rewarded — financial controls, quality systems, performance metrics. "What gets measured gets managed."
  6. Rituals and routines: The daily behaviours and practices that signal "how things are done around here" — meetings, onboarding, training, social events

The paradigm is the core set of assumptions and beliefs — the organisation's "way of seeing the world." To change strategy, the paradigm often needs to change, which requires addressing ALL six elements of the cultural web.

Leadership Styles

Leadership style affects how strategy is implemented and how change is managed. Different situations require different styles.

StyleDescriptionWhen effective
Autocratic / directiveLeader makes decisions unilaterally. Clear instructions. Limited consultation.Crisis situations, urgent decisions, inexperienced teams, turnaround scenarios where speed is essential
Democratic / participativeLeader involves team in decision-making. Seeks input, builds consensus.Complex decisions requiring diverse perspectives, building commitment, skilled/experienced teams, long-term strategic planning
TransformationalLeader inspires and motivates through vision, purpose, and personal example. Challenges the status quo. Empowers followers.Major strategic change, culture transformation, building a high-performance organisation, innovation-driven environments
TransactionalLeader focuses on clear structures, rewards for performance, and corrective action for deviations. Management by objectives/exception.Stable environments, well-defined tasks, maintaining operational efficiency, managing routine performance
Laissez-faireLeader provides minimal direction. Team has high autonomy.Highly skilled, self-motivated professionals (research teams, creative agencies). Rarely appropriate for strategic change.

Situational leadership: The most effective leaders adapt their style to the situation — there is no single "best" style. The appropriate style depends on: the urgency of the situation, the experience and maturity of the team, the complexity of the task, the organisation's culture, and the nature of the change required.

Project Management and Implementation Planning

Strategic initiatives are often managed as projects — temporary endeavours with defined objectives, scope, timeline, and resources.

Key elements of effective project management for strategy implementation:

  • Clear objectives and scope: Define what the project will deliver, the boundaries (in scope/out of scope), and success criteria (measurable outcomes)
  • Project plan: Break the project into phases, milestones, and tasks. Define dependencies, timelines, and resource requirements. Tools: Gantt charts, critical path analysis, work breakdown structures.
  • Governance: Clear project sponsor (senior leader with authority and accountability), project board/steering committee (oversight and decision-making), project manager (day-to-day delivery)
  • Resource allocation: Assign people, budget, and technology. Ensure resources are available when needed. Manage competing demands on shared resources.
  • Risk management: Identify project risks (delays, cost overruns, scope creep, resource constraints, stakeholder resistance). Assess likelihood and impact. Develop mitigation plans.
  • Communication plan: Define who needs to know what, when, and how. Regular progress reporting. Stakeholder engagement strategy.
  • Monitoring and control: Track progress against the plan. Manage scope changes through a formal change control process. Address issues promptly. Use earned value analysis or other tracking methods.
  • Benefits realisation: Track whether the strategic benefits are actually being achieved after implementation. The project is not complete when the system goes live — benefits often take months or years to materialise.

Examiner Focus

Change management models (Lewin and Kotter) are tested very frequently. For Kotter: apply ALL eight steps to the scenario in sequence. For each step: explain WHAT needs to be done and HOW (specific to the scenario). Generic answers ("communicate the vision") score poorly — the examiner wants "the CEO should hold town hall meetings for all 500 branches explaining the business case with specific data on declining footfall."

Common Pitfall

Students often describe the models correctly but fail to APPLY them. Listing Kotter's eight steps without linking each one to the specific scenario earns few marks. Always say: "In THIS situation, step 3 means..." and give specific, practical recommendations.

Study Tip

The cultural web is excellent for scenario analysis. If the question describes an organisation's culture and asks you to analyse barriers to change: map each element of the web (stories, symbols, power, structures, controls, rituals) and identify how each one reinforces the existing paradigm and what needs to change to support the new strategy.

Examiner Focus

McKinsey 7S: the examiner often asks "what needs to change to implement this strategy?" Use 7S to systematically assess each element: Strategy (already defined), Structure (does it support the strategy?), Systems (IT, processes), Shared values (culture), Skills (capabilities needed), Staff (right people?), Style (leadership approach). Identify misalignments and recommend changes.

Watch Out

When recommending an organisational structure, there is NO "one best structure." Always evaluate advantages AND disadvantages for the specific context. A matrix structure sounds sophisticated but creates confusion in many organisations. A functional structure may be perfectly adequate for a focused, single-product firm.

Study Tip

Leadership styles: the examiner may describe a leader's approach and ask whether it is appropriate. Use situational leadership — the "right" style depends on the context. A transformational style suits major change; a transactional style suits operational efficiency; an autocratic style suits crisis. The best leaders adapt.

Key Definitions

Functional structure

Organised by business function (marketing, finance, operations). Clear specialisation but may create silos. Best for single-product, stable environments.

Divisional structure

Organised by product, region, or customer. Semi-autonomous divisions. Clear accountability but duplication of functions. Best for large, diversified firms.

Matrix structure

Dual reporting — functional manager + project/product manager. Combines expertise with focus but creates complexity, confusion, and potential conflict.

McKinsey 7S

Seven interdependent elements for effective implementation: Strategy, Structure, Systems (hard) + Shared values, Skills, Staff, Style (soft). All must be aligned. Shared values are central.

Lewin's three-stage model

Unfreeze (create awareness of need for change), Change (implement new approaches), Refreeze (embed changes in culture and systems). Force field analysis: driving vs restraining forces.

Kotter's eight steps

Sequential change process: urgency → guiding coalition → vision → communicate → remove barriers → short-term wins → sustain acceleration → embed in culture. Failure at any step undermines the whole effort.

Power culture (Handy)

Central figure controls. Quick decisions, entrepreneurial. Risk: over-dependency. Common in start-ups. Symbol: web (all threads lead to the centre).

Role culture (Handy)

Bureaucratic — defined roles, rules, hierarchy. Stable, predictable. Risk: inflexible, slow to change. Common in government, banks. Symbol: temple (pillars = functions).

Cultural web (Johnson)

Six elements surrounding the paradigm: stories, symbols, power structures, organisational structures, control systems, rituals and routines. Used to analyse and change culture.

Paradigm

The core set of taken-for-granted assumptions that shape how the organisation sees the world. The central element of the cultural web. Changing the paradigm requires addressing all six web elements.

Transformational leadership

Inspires through vision, purpose, and personal example. Challenges the status quo. Empowers followers. Most effective for major strategic change and culture transformation.

Force field analysis (Lewin)

Change is driven by driving forces and resisted by restraining forces. Change occurs when driving forces exceed restraining. Strategy: strengthen drivers or weaken restrainers (often more effective).

  • McKinsey 7S: Strategy, Structure, Systems (hard) + Shared values, Skills, Staff, Style (soft). All seven must be aligned for effective implementation. Shared values at the centre influence all others.
  • Lewin's model: Unfreeze (create awareness + urgency) → Change (implement new approaches) → Refreeze (embed in culture and systems). Force field analysis: strengthen driving forces or weaken restraining forces.
  • Kotter's 8 steps: urgency → guiding coalition → vision → communicate → remove barriers → short-term wins → sustain acceleration → embed in culture. Sequential — failure at any step undermines the whole process.
  • Handy's cultures: power (central figure, entrepreneurial), role (bureaucratic, rules-driven), task (project teams, flexible), person (individual-centred, professional partnerships).
  • Johnson's cultural web: stories, symbols, power structures, organisational structures, control systems, rituals and routines — all surrounding the paradigm (core assumptions). To change strategy, often need to change the paradigm by addressing all six elements.
