Change management is one of the most examinable themes in strategic and organisational management because it connects strategy, structure, people, culture, and performance. For UNISA students preparing for MNG3702, the ability to compare change models clearly and apply them to practical business situations is often more important than memorising definitions alone. This study guide presents the major change management models, compares their assumptions and uses, and shows how they are commonly applied in South African organisational contexts.
1. The Meaning of Change Management in MNG3702
Change management refers to the structured process of moving an organisation from a current state to a desired future state while reducing resistance and maintaining performance. In MNG3702, the topic is important because organisations operate in environments shaped by competition, technology, regulation, labour relations, digital transformation, and customer expectations. Change is therefore not an occasional event but a continuous managerial responsibility.
1.1 Why change management matters in strategic management
In strategic management, an organisation’s strategy is only as strong as its ability to implement it. A strategic plan can be well designed, but if employees do not adopt the required behaviours, if systems are not updated, or if leadership does not manage transition properly, the strategy fails in practice. Change management fills the gap between strategic intent and operational reality. It helps managers answer questions such as:
- How should the organisation move from old routines to new ones?
- What should leaders do when employees resist a new system?
- How can performance be protected during transition?
- Which parts of the organisation must change first: structure, people, culture, or processes?
- How do we know whether the change has been successfully embedded?
For exam purposes, change management is often tested as both a process and a set of models. The process view asks how change unfolds over time. The model view asks which framework best explains or supports that process. UNISA exam questions often require comparison, application, evaluation, and critical discussion rather than simple description.
1.2 Types of organisational change
A useful distinction for exam answers is between different kinds of change, because the choice of model often depends on the type of change involved.
Incremental change
Incremental change is gradual and continuous. It involves small adjustments to procedures, reporting lines, technology, or service delivery. Because the shift is moderate, models like ADKAR or Kotter’s 8-Step Model can be effective, especially when communication and employee buy-in are central concerns.
Transformational change
Transformational change is deep, broad, and often disruptive. It may involve restructuring, mergers, digital transformation, turnaround strategies, or culture change. In such cases, Lewin’s model, McKinsey 7-S, and the Burke–Litwin model are especially useful because they help managers think about alignment, system-wide effects, and reinstitution of the new state.
Reactive change
Reactive change occurs in response to crises such as declining sales, regulatory pressure, labour conflict, or technological disruption. It often needs urgency and strong leadership. Kotter’s model is frequently associated with this kind of change because it begins with a sense of urgency.
Proactive change
Proactive change is initiated before a crisis becomes severe. It is based on forecasting, strategic foresight, and continuous improvement. In this case, managers may use ADKAR for individual adoption and McKinsey 7-S for organisational alignment.
1.3 The human side of change
A common exam trap is to describe change as if it is only about structures and systems. In reality, change succeeds or fails largely because of people. Employees may fear job loss, loss of status, loss of competence, or simply uncertainty. Resistance is not always irrational; sometimes it reflects poor planning, unclear communication, or genuine operational risk.
Human reactions to change often include:
- Denial: “This will not happen.”
- Anger or frustration: “Why are they doing this to us?”
- Bargaining: “Maybe we can keep part of the old system.”
- Exploration: “How will this affect my role?”
- Commitment: “This is now part of how we work.”
These responses connect well to the practical value of structured change models. A good model helps leaders manage emotions, not only tasks.
1.4 Core barriers to change
When answering MNG3702 exam questions, it is useful to identify common barriers. These barriers often determine why one model is preferable to another.
| Barrier | Description | Effect on change |
|---|---|---|
| Resistance from employees | People fear uncertainty, loss of power, or additional workload | Slows adoption and weakens commitment |
| Poor communication | Goals and reasons for change are not clearly explained | Creates confusion and rumours |
| Weak leadership | Leaders do not model the change or provide direction | Reduces trust and momentum |
| Cultural misfit | New practices conflict with existing values and norms | Change feels unnatural and is rejected |
| Inadequate resources | The organisation lacks time, money, systems, or skills | Implementation becomes inconsistent |
| Change fatigue | Employees experience too many simultaneous changes | Reduces morale and performance |
| Misalignment | Strategy, structure, systems, and people are not aligned | New change is not sustained |
The key idea is that change management is not just implementation. It is a discipline of diagnosis, design, communication, support, and reinforcement.
2. Lewin’s Change Model: Unfreeze, Change, Refreeze
Kurt Lewin’s model remains one of the most widely examined frameworks in management studies because of its simplicity and clarity. It presents change as a three-stage process: unfreeze, change, and refreeze. Although the model is old, it is still useful because it captures the logic of moving from stability through transition to a new stable state.
2.1 Stage 1: Unfreeze
The unfreeze stage prepares the organisation for change. The main purpose is to break the status quo and reduce the force of existing habits, routines, and assumptions. Without unfreezing, people tend to cling to familiar behaviour even when they know change is necessary.
Activities in the unfreeze stage may include:
- communicating the need for change
- creating awareness of current problems
- showing gaps between current performance and strategic goals
- involving influential stakeholders
- reducing fear through transparency
- challenging existing beliefs and norms
In exam language, unfreezing is about creating readiness. Managers must make people understand why change is necessary before asking them to behave differently.
Strength of the unfreeze stage
The biggest strength is that it recognises psychological preparedness as essential. Many failed transformations happen because leaders announce change without preparing people emotionally and cognitively.
Limitation of the unfreeze stage
The weakness is that it can oversimplify how change starts. In complex organisations, different departments may be at different levels of readiness, so unfreezing is not always a single event.
2.2 Stage 2: Change
The change stage is the transition period when the organisation moves from old ways to new ways. During this stage, new behaviours, systems, and processes are introduced. Employees begin learning new skills, adopting new routines, and adjusting to uncertainty.
Typical actions include:
- training and development
- pilot implementation
- restructuring roles and responsibilities
- introducing new technology
- changing workflow or reporting structures
- coaching and support
This is often the most uncomfortable phase because performance may temporarily decline as people learn. Productivity may fall before it improves. That is why leaders must expect a dip and manage it carefully rather than interpret it as failure.
What examiners look for
Students should explain that the change stage is not just the introduction of a new policy. It includes behavioural and cultural adaptation. If people receive new software but continue using old habits, the change has not truly occurred.
2.3 Stage 3: Refreeze
Refreezing stabilises the new state so that it becomes the normal way of working. This stage is about reinforcement. Without refreezing, people may revert to old habits once attention shifts elsewhere.
Refreezing can involve:
- updating policies and procedures
- embedding new performance measures
- rewarding compliance and innovation
- reinforcing desired behaviour through leadership
- integrating change into culture and training
- monitoring results over time
Strength of the refreeze stage
Refreezing highlights the importance of sustainability. Change is not complete when the new system is launched; it is complete when the new behaviour becomes routine.
Limitation of the refreeze stage
Critics argue that modern organisations are often too dynamic to “freeze.” In fast-changing industries, continuous adaptation may be more realistic than stable refreezing. This criticism is especially relevant in digital and technology-driven environments.
2.4 Why Lewin still matters in exams
Lewin is easy to remember and easy to apply. For UNISA exams, it works well in essays, short questions, and case studies because it gives a logical sequence. It is especially useful for answering questions on preparing people for change and making the new approach sustainable.
However, it should not be presented as the only or best model for every situation. A strong exam answer acknowledges both its value and its limits.
2.5 Example application
Consider a South African retail company introducing a new inventory management system across its stores. During unfreezing, management explains that stock losses, poor visibility, and delayed replenishment are hurting profits. During change, store managers receive training and the new system is piloted in selected branches. During refreezing, the company updates reporting routines, links performance bonuses to accurate stock control, and includes the system in induction training for new employees.
This example shows why Lewin is practical: it translates strategy into a sequence of manageable steps.
3. Kotter’s 8-Step Model and ADKAR: Leading Change Through People
Kotter’s and ADKAR’s models are frequently compared because both focus on implementation, adoption, and people-centred change, but they operate at different levels. Kotter provides an organisational roadmap for leading large-scale transformation, while ADKAR focuses on individual change adoption. Understanding the difference is essential for exam success.
3.1 Kotter’s 8-Step Model
John Kotter developed a widely used model for leading transformation in eight steps:
- Create a sense of urgency
- Build a guiding coalition
- Form a strategic vision and initiatives
- Enlist a volunteer army
- Enable action by removing barriers
- Generate short-term wins
- Sustain acceleration
- Institute change
Each step builds momentum and reduces the risk of failure.
Step 1: Create a sense of urgency
Change often fails because people are comfortable. Urgency makes the need for change visible. Managers may use market data, customer complaints, declining profits, or regulatory threats to show why action is necessary now.
Step 2: Build a guiding coalition
A single leader rarely changes an organisation alone. A coalition of influential managers and respected employees provides credibility, energy, and coordination.
Step 3: Form a strategic vision and initiatives
The organisation needs a clear picture of what the future should look like. The vision must be simple, credible, and motivating.
Step 4: Enlist a volunteer army
This step involves broad participation. Change is not limited to top management; it depends on people throughout the organisation.
Step 5: Enable action by removing barriers
Barriers may include bureaucracy, outdated systems, unhelpful managers, lack of skills, or resistance from informal power holders.
Step 6: Generate short-term wins
Short-term wins prove that the change is working. They build confidence and reduce scepticism.
Step 7: Sustain acceleration
After early success, organisations must keep pushing. Premature celebration can kill momentum.
Step 8: Institute change
Finally, change must be embedded in culture, systems, leadership succession, and performance management.
3.2 Why Kotter is powerful in exams
Kotter is strong because it provides a detailed and realistic path for large-scale change. It emphasises leadership, communication, coalitions, and momentum. In essay questions, it is useful to discuss the model as a guide to implementation rather than merely a checklist.
A strong answer should also mention that Kotter’s model is not linear in a rigid sense. In real organisations, steps may overlap. For example, short-term wins may need to be communicated while barriers are still being removed.
3.3 Limitations of Kotter’s model
Kotter’s model has several limitations:
- It can be too top-down if applied rigidly.
- It assumes that change can be guided through a sequence of steps, which may not fit highly fluid environments.
- It focuses more on leadership of change than on deep diagnostic analysis.
- It may understate the role of organisational politics and conflict.
- It may be difficult to implement in resource-constrained environments where continuous urgency creates fatigue.
These criticisms are useful in comparative essay questions because they show critical thinking.
3.4 ADKAR model
ADKAR stands for Awareness, Desire, Knowledge, Ability, and Reinforcement. It is a people-focused model that explains the five outcomes each individual needs in order to adopt change successfully.
Awareness
People must understand why change is needed. Without awareness, they may see the change as arbitrary.
Desire
People must want to participate and support the change. Awareness alone does not produce commitment.
Knowledge
People need to know how to change, including procedures, expectations, and new skills.
Ability
Knowledge is not enough unless individuals can perform the new behaviour in practice.
Reinforcement
New behaviour must be reinforced through rewards, feedback, monitoring, and leadership support.
3.5 How ADKAR differs from Kotter
Kotter is a leadership and organisational model. ADKAR is an individual adoption model. This distinction is extremely important for exams.
- Kotter asks: How do leaders move the organisation through change?
- ADKAR asks: What must each person experience to adopt the change?
Both can be used together. For example, Kotter can guide the organisational strategy, while ADKAR can help managers support individual employees during implementation.
3.6 Comparison table: Kotter and ADKAR
| Feature | Kotter’s 8-Step Model | ADKAR Model |
|---|---|---|
| Main focus | Organisational change leadership | Individual change adoption |
| Structure | Eight-step sequence | Five outcomes |
| Best use | Large transformation programmes | Training, adoption, behaviour change |
| Emphasis | Vision, coalition, momentum, institutionalisation | Awareness, desire, knowledge, ability, reinforcement |
| Strength | Provides implementation roadmap | Explains why individuals accept or resist change |
| Limitation | Can be top-down and rigid | May not fully address organisational politics |
3.7 Practical example
A university implementing a new online learning management system can use Kotter to build urgency around student digital expectations, form a cross-functional implementation team, generate pilot successes, and embed the platform in policy. ADKAR can then be used to assess whether lecturers and administrators have awareness of the need for the system, desire to use it, knowledge of its functions, ability to teach or operate it, and reinforcement through support and recognition.
This kind of layered application is exactly the sort of depth UNISA examiners appreciate.
4. McKinsey 7-S and the Burke–Litwin Model: Alignment and Organisational Diagnosis
While Lewin, Kotter, and ADKAR focus on the process of change, the McKinsey 7-S model and the Burke–Litwin model are especially valuable for diagnosing organisational alignment. They help managers see how different components of the organisation influence one another.
4.1 McKinsey 7-S Model
The McKinsey 7-S model argues that successful organisations require alignment among seven internal elements:
- Strategy
- Structure
- Systems
- Shared values
- Style
- Staff
- Skills
These are divided into hard elements and soft elements.
Hard elements
- Strategy
- Structure
- Systems
These are easier to identify, document, and change formally.
Soft elements
- Shared values
- Style
- Staff
- Skills
These are more intangible but often more influential in long-term change.
4.2 Why the 7-S model is important
The central insight of the 7-S model is that change in one part of an organisation affects other parts. For example, if a company changes strategy from local expansion to digital service delivery, it may also need to change structure, systems, skills, leadership style, and even shared values. If these elements are not aligned, the strategy will be undermined.
This model is particularly useful in exam answers that ask about alignment or organisational fit. A strategic decision is never isolated. It always has ripple effects.
4.3 Applying the 7-S model
Suppose a logistics company in South Africa wants to improve delivery speed by adopting a real-time tracking system.
- Strategy: Focus on faster, more transparent customer service.
- Structure: Create a digital operations unit.
- Systems: Install tracking software and update reporting procedures.
- Shared values: Promote responsiveness and customer centricity.
- Style: Encourage data-driven leadership and quick decision-making.
- Staff: Hire or retrain employees with digital skills.
- Skills: Improve route planning, system use, and exception management.
If one of these elements is ignored, the change may fail. For instance, installing software without training staff or changing management style creates frustration and poor usage.
4.4 Burke–Litwin Model
The Burke–Litwin model is a more detailed diagnostic framework that links organisational transformation to internal and external variables. It distinguishes between transformational factors and transactional factors.
Transformational factors
These include:
- external environment
- mission and strategy
- leadership
- organisational culture
Transactional factors
These include:
- structure
- management practices
- systems
- work unit climate
- task requirements and individual skills
- individual needs and values
- motivation
- performance
The model suggests that external pressures influence mission and strategy, which affect leadership and culture, which then shape systems, structure, management practices, and individual performance.
4.5 Why Burke–Litwin is more complex than 7-S
The Burke–Litwin model is more explicit about causal relationships. It shows how change starts in the external environment and travels through the organisation. It is useful when the problem is not simply misalignment, but a deeper organisational performance issue.
In exam answers, Burke–Litwin is especially useful where the case study involves:
- mergers and acquisitions
- major restructuring
- turnaround strategy
- poor organisational climate
- declining performance linked to leadership and culture
4.6 Comparison table: 7-S and Burke–Litwin
| Feature | McKinsey 7-S | Burke–Litwin |
|---|---|---|
| Main purpose | Alignment of organisational elements | Diagnosis of transformation and performance |
| Scope | Internal organisational fit | External and internal causal relationships |
| Complexity | Moderate | High |
| Best use | Strategy implementation and alignment | Large-scale transformation and performance analysis |
| Core idea | All seven elements must align | Change flows from external environment to individual performance |
| Strength | Simple and intuitive | Deep and diagnostic |
| Limitation | Less explicit about causality | More complex and harder to remember |
4.7 Comparative insight for exams
A good comparative answer should show that both models help managers avoid the mistake of changing only one part of the organisation. A new strategy without a supportive structure, system, or culture is unlikely to succeed. The difference is that the 7-S model emphasises alignment, while Burke–Litwin emphasises transformational causality and performance outcomes.
5. Comparative Evaluation of Change Models for UNISA Exam Answers
This section is especially important because UNISA questions often ask students to compare, critique, or recommend a model for a specific scenario. A strong answer does not merely list models; it evaluates their strengths, weaknesses, and fit for purpose.
5.1 Comparing the models by focus
| Model | Main focus | Best described as |
|---|---|---|
| Lewin | Transition through stages | Process model |
| Kotter | Leading organisational transformation | Leadership roadmap |
| ADKAR | Individual adoption of change | People adoption model |
| McKinsey 7-S | Organisational alignment | Diagnostic alignment model |
| Burke–Litwin | Organisational transformation and performance | Causal diagnostic model |
This table is useful because it summarises the exam logic: the models are not competing in the sense of one being universally superior. They answer different questions.
5.2 Which model is best for which situation?
When Lewin is most useful
Lewin is best for explaining the basic logic of change, especially when the question asks about stages, resistance, or institutionalising a new way of working. It is especially suitable for shorter exam questions because it is easy to structure.
When Kotter is most useful
Kotter is best for large transformation programmes where leadership, communication, urgency, and coalition-building are central. It is strong in case studies involving mergers, digital change, turnaround strategies, or organisational renewal.
When ADKAR is most useful
ADKAR is best when the question focuses on employee adoption, training, change resistance, or behavioural readiness. It is excellent for analysing why people do not embrace new processes even when the strategy is sound.
When McKinsey 7-S is most useful
7-S is best when the question is about strategic alignment or diagnosing why a change is not working. It is helpful when strategy and operations seem disconnected.
When Burke–Litwin is most useful
Burke–Litwin is best when the question is about deep organisational performance problems, leadership failure, or culture change. It is more analytical and more sophisticated, which can strengthen higher-mark exam essays.
5.3 Strengths and weaknesses in comparative form
Lewin
Strengths
- simple to remember
- easy to apply
- useful for basic explanations of transition
Weaknesses
- too linear
- oversimplifies complex change
- “refreeze” may be unrealistic in rapidly changing environments
Kotter
Strengths
- practical for large-scale change
- highlights urgency, coalition, and momentum
- clearly links leadership to implementation
Weaknesses
- can be top-down
- assumes sequence and control
- may not fit agile environments perfectly
ADKAR
Strengths
- focuses on the individual
- useful for training and adoption
- good diagnostic tool for resistance
Weaknesses
- not a full organisational strategy
- may ignore macro-level politics and structure
- less useful by itself for complex transformation
McKinsey 7-S
Strengths
- emphasises alignment
- broad enough to cover both hard and soft elements
- useful for diagnosing inconsistencies
Weaknesses
- does not provide a step-by-step change process
- can become descriptive if not applied carefully
- less explicit about sequencing
Burke–Litwin
Strengths
- highly analytical
- connects external environment to organisational performance
- useful for transformation and culture analysis
Weaknesses
- complex
- can be difficult to remember in an exam
- may be too detailed for short questions
5.4 Critical perspective: no single best model
A strong UNISA answer should show that no model is universally best. The correct model depends on:
- the scale of change
- the time available
- the level of resistance
- the organisational culture
- leadership capability
- whether the issue is adoption, alignment, or transformation
For example, if an organisation is introducing a minor process improvement, ADKAR may be enough. If it is undergoing a merger, Kotter or Burke–Litwin may be more suitable. If the problem is lack of fit between strategy and structure, 7-S may be the best diagnostic tool.
5.5 Comparative mini-case
Imagine a public-sector organisation in South Africa introducing a new digital records system.
- Lewin would help structure the transition into unfreeze, change, refreeze.
- Kotter would help leaders create urgency, build a coalition, and generate short-term wins.
- ADKAR would help assess whether employees understand the change and have the skills to use the system.
- 7-S would help check whether structure, systems, staff, and shared values are aligned.
- Burke–Litwin would help diagnose whether the problem stems from external pressure, leadership, culture, or work-unit climate.
This shows that the models are complementary. In practice, managers often use more than one framework at the same time.
6. How to Answer MNG3702 Exam Questions Effectively
Many students lose marks not because they do not know the models, but because they do not answer the question in the required way. This section translates knowledge into exam technique.
6.1 Common command words and how to respond
Define
Provide a concise explanation of the concept and, if appropriate, mention the key model or theory.
Explain
Go beyond definition. Show how the concept works and why it matters.
Discuss
Present arguments, examples, implications, and sometimes counter-arguments.
Compare
Show similarities and differences. Use a structured approach, ideally with a table or balanced paragraphs.
Critically evaluate
Assess strengths and weaknesses, limitations, and practical relevance. Do not just describe.
Apply
Use the theory in a specific case study or business scenario. This is where marks are often won.
6.2 Structure for a strong essay answer
A reliable structure is:
-
Introduction
- Define change management
- State the relevance of the models
- Mention the models that will be discussed
-
Body
- Describe each model accurately
- Compare them
- Evaluate strengths and limitations
- Apply them to a relevant example
-
Conclusion
- Summarise which model is suitable for which context
- Reinforce the idea that change is context-dependent
6.3 How to integrate theory and application
The highest-scoring answers usually combine theory with practical application. For example, instead of saying “Kotter emphasises urgency,” write: “Kotter emphasises urgency because employees often resist change when the benefits are not visible; in a declining retail business, management may need to show falling sales and customer complaints to make the need for change undeniable.”
This kind of answer does three things:
- it names the model,
- it explains the principle,
- it applies it to a realistic scenario.
6.4 Using case studies in exam answers
Even if the exam question does not provide a full case study, you can create a short, realistic scenario to support your argument.
Examples:
- a university moving to hybrid learning
- a bank implementing digital onboarding
- a hospital changing its patient record system
- a logistics firm adopting route optimisation software
- a municipality improving service delivery through process redesign
A good case example should be consistent, specific, and directly linked to the model being discussed.
6.5 Typical mistakes to avoid
- Describing one model in great detail without comparing it to others
- Writing generic statements like “change is important” without linking them to the question
- Confusing organisational change with individual behaviour change
- Using Lewin as if it explains everything
- Treating Kotter as a rigid checklist with no critique
- Ignoring the role of communication and leadership
- Failing to apply the model to a realistic organisational setting
- Repeating the same point in different words instead of adding depth
6.6 A high-quality comparative conclusion
A strong conclusion might argue that:
- Lewin is useful for basic staging of change,
- Kotter is strong for large transformation leadership,
- ADKAR explains individual adoption,
- 7-S ensures organisational alignment,
- Burke–Litwin provides deep causal diagnosis.
This kind of conclusion demonstrates both knowledge and judgement.
7. South African and UNISA-Relevant Contexts for Change Management Models
For UNISA students, contextual relevance matters. Examiners often value answers that reflect South African organisational realities because they show practical understanding rather than abstract memorisation. Change management in South Africa is shaped by economic pressure, service delivery demands, digital transformation, labour relations, inequality, and public-sector reform.
7.1 Public sector change
Many public institutions need change because of service delivery challenges, administrative backlogs, technology gaps, and governance pressures. In the public sector, change is often difficult because of bureaucracy, political oversight, and labour concerns. Kotter can help create urgency and leadership momentum, while ADKAR can help address employee concerns and build competence.
For example, if a provincial department introduces an electronic document management system, resistance may arise from staff who are accustomed to manual filing. The change is not simply technical. It affects workflow, accountability, and skill requirements. Lewin can explain the transition stages, ADKAR can support training and adoption, and 7-S can ensure that systems, staff, and structures are aligned.
7.2 Higher education change
Universities in South Africa have faced significant pressure to modernise teaching, student support, administrative systems, and digital platforms. In a university setting, resistance may come from academics, administrators, and students who differ in readiness and expectations.
Change in higher education often needs:
- leadership communication,
- consultation,
- training,
- phased implementation,
- and alignment between academic goals and support systems.
Kotter is useful because it emphasises vision and coalition-building across departments. ADKAR is also useful because lecturers and support staff adopt change at different rates. Burke–Litwin can help diagnose whether the root issue is leadership, culture, or external pressure.
7.3 Private sector change
Private companies may use change models to remain competitive, reduce costs, improve customer experience, or implement digital technologies. In the private sector, the pressure for measurable results is often stronger, so short-term wins matter significantly.
For example, a financial services company introducing mobile banking upgrades may use Kotter to build urgency around customer expectations, 7-S to align structure and skills, and ADKAR to support frontline staff training. The model choice depends on whether the main challenge is leadership, adoption, or organisational fit.
7.4 Labour relations and resistance in South Africa
Labour relations are central in South African organisations. Change proposals can trigger concerns about job security, workload, bargaining conditions, and fairness. Resistance should therefore be understood not as simple obstruction, but as a response to perceived threats or poor consultation.
An exam answer gains depth by recognising that change management in South Africa often requires:
- consultation with unions,
- fair communication,
- trust-building,
- and phased implementation.
In such contexts, Kotter’s guiding coalition may need to include labour representatives or employee champions, while ADKAR can help managers understand the individual and emotional aspects of adoption.
7.5 Digital transformation and the future of change
Digital transformation is now one of the most common reasons organisations change. It affects retail, banking, education, logistics, health care, and public administration. Digital change is especially useful for exam discussion because it shows how multiple models can be integrated.
A digital transformation programme typically needs:
- Lewin for transition structure,
- Kotter for leadership and momentum,
- ADKAR for user adoption,
- 7-S for alignment,
- Burke–Litwin for deeper transformation diagnosis.
This integrated approach is likely to impress in an exam because it shows analytical maturity.
8. Consolidated Revision Notes, Memory Triggers, and Final Comparison
This final section distils the major ideas into revision-friendly form while still preserving analytical depth. It is designed to help with last-minute study, essay planning, and comparison questions.
8.1 One-line summaries of each model
- Lewin: Change happens by unfreezing the old state, moving through change, and refreezing the new state.
- Kotter: Successful transformation requires urgency, coalition, vision, participation, barrier removal, wins, momentum, and institutionalisation.
- ADKAR: Individuals adopt change when they develop awareness, desire, knowledge, ability, and reinforcement.
- McKinsey 7-S: Strategy succeeds when strategy, structure, systems, shared values, style, staff, and skills are aligned.
- Burke–Litwin: Organisational performance changes through a causal chain linking external environment, leadership, culture, systems, and individual outcomes.
8.2 Memory clues for exam recall
- Lewin = stage model
- Kotter = leadership roadmap
- ADKAR = individual adoption
- 7-S = alignment model
- Burke–Litwin = causal diagnostic model
These labels help avoid confusion when comparing frameworks in the exam.
8.3 Comparative revision table
| Model | Core question | Main advantage | Main limitation | Best exam use |
|---|---|---|---|---|
| Lewin | How does change unfold in stages? | Simple and memorable | Too linear | Basic explanations and transition questions |
| Kotter | How do leaders drive large change? | Practical and detailed | Can be rigid | Essays and transformation case studies |
| ADKAR | How do individuals adopt change? | People-centred | Not a full organisational model | Resistance and training questions |
| McKinsey 7-S | Are organisational elements aligned? | Strong diagnostic fit | No step-by-step process | Strategy implementation and fit |
| Burke–Litwin | What causes performance change? | Deep and analytical | Complex | High-level diagnostic essays |
8.4 What a top exam answer should sound like
A top answer in MNG3702 will usually:
- define change management accurately,
- distinguish between process, adoption, alignment, and diagnostic models,
- compare strengths and weaknesses,
- apply the models to a realistic organisational context,
- and conclude with a context-based recommendation.
Such an answer does not simply say that all models are useful. It explains why, when, and how each model is useful.
8.5 Final comparative insight
If the topic is approached from a strategic management perspective, the deepest lesson is that change is not a single event but a managed transition involving people, systems, culture, and leadership. Lewin gives the basic skeleton of change, Kotter shows how to mobilise an organisation, ADKAR explains how individuals adopt new behaviour, 7-S ensures alignment, and Burke–Litwin reveals how external pressures and internal factors combine to affect performance. Together, these models offer a complete toolkit for analysing organisational change in UNISA exam scenarios and in real South African institutions.
8.6 Last-minute revision checklist
Before the exam, make sure you can:
- define change management in one or two strong sentences
- explain Lewin’s three stages without confusion
- list Kotter’s eight steps in the correct order
- expand ADKAR into its five components
- identify the seven elements of the McKinsey 7-S model
- distinguish transformational from transactional factors in Burke–Litwin
- compare at least three models in one answer
- apply a model to a South African organisational example
- critique the limitations of each model
- recommend the most suitable model for a given case
Mastering these points will make it easier to respond confidently to both short questions and essay-style questions in MNG3702.
