Lewin’s Force Field Analysis Theory (VCE SSCE Business Management): Revision Notes
Lewin's Force Field Analysis Theory
Understanding change in business
Businesses face constant change in their operating environment. To manage change effectively, leaders and managers must adopt a proactive approach rather than simply reacting when changes occur. Successful organisations anticipate, initiate and welcome change as an opportunity for growth and improvement.
Change management is a critical skill in modern business. Organisations that embrace change strategically are better positioned to adapt to market conditions, technological advancements, and evolving customer needs.
What is Force Field Analysis?
In 1969, management theorist Kurt Lewin developed Force Field Analysis as a framework for understanding how change occurs within organisations. Drawing from principles in physical sciences, Lewin created this tool to help businesses analyse problems and evaluate the impact of potential changes.
Lewin defined a problem situation as a gap between the current state and the desired state. His theory identifies two types of forces at work:
Driving forces – factors that push towards and support the proposed change
Restraining forces – factors that resist, block or hinder the change process
The theory uses a simple visual model to map these competing forces, allowing decision-makers to discuss and evaluate the situation systematically.
Driving forces
Driving forces are pressures that push a situation in a particular direction, supporting the intended goal or change. These forces initiate change and maintain momentum throughout the change process.
Examples of driving forces include:
- Management support and leadership
- Technological advancements
- Employee suggestions and engagement
- New legislation or regulatory requirements
- Market opportunities
- Competitive pressures
Consider this scenario: If a business wants to improve productivity in a work team, driving forces might include supportive management, available technology, employee input or new legal requirements. Each of these factors creates momentum towards the desired change.
Restraining forces
Restraining forces work against the driving forces, acting to slow down, block or prevent change from occurring. These represent both personal and organisational resistance to change.
Examples of restraining forces include:
- Employee apathy or active resistance
- Limited financial resources
- Cost concerns
- Organisational inertia (the tendency to maintain the status quo)
- Management opposition
- Inadequate infrastructure
- Competitive threats
- Restrictive legislation
These forces actively oppose any changes that managers or business owners attempt to implement.
Understanding resistance is crucial: Restraining forces aren't necessarily negative or irrational. They often represent legitimate concerns about costs, risks, or disruption. Successful change management requires acknowledging and addressing these concerns rather than dismissing them.
The four-step model
Lewin's Force Field Analysis follows a structured four-step process:
1. Weighting
Managers and leaders identify all driving and restraining forces, then assign each force a numerical score based on its perceived importance and strength. This typically uses a scale (such as ), where higher numbers indicate stronger forces.
2. Ranking
Forces are arranged in order from most important to least important. This prioritisation helps decision-makers focus on the most significant factors affecting the change.
3. Implementing a response
After weighing up all factors, the business makes an informed decision about whether and how to proceed with the change.
4. Evaluating a response
Following implementation, the business must continuously monitor the situation to verify that the decision was correct and the change is achieving its intended outcomes.
Applying a structured approach
When using Force Field Analysis, businesses should follow these steps:
- Define the goal – clearly articulate the vision for change
- Identify driving forces – list all internal and external factors supporting the change
- Identify restraining forces – list all internal and external factors opposing the change
- Assign numerical weightings – score each identified force to indicate its strength
- Implement and monitor – take action and continuously evaluate progress towards the goal
Systematic approach matters: Using a structured methodology ensures that decisions are based on comprehensive analysis rather than intuition alone. This increases the likelihood of successful change implementation and helps justify decisions to stakeholders.
Conditions for successful change
According to Lewin, the likelihood of successful change implementation depends on the relative strength of driving versus restraining forces. He identified three possible scenarios:
Scenario 1: Driving forces dominate
When driving forces are stronger than restraining forces, the change is likely to succeed. The momentum pushing towards change overcomes the resistance.
Scenario 2: Forces are balanced
If driving forces and restraining forces have similar strength, the change will probably not succeed. The opposing pressures cancel each other out, creating a stalemate with no movement.
Scenario 3: Restraining forces dominate
When restraining forces are more powerful than driving forces, the change is unlikely to be successfully introduced. The resistance is too strong to overcome.
Key insight: Businesses must create conditions that strengthen driving forces and reduce restraining forces to maximise the chances of successful change. This dual approach is more effective than focusing solely on one type of force.
Worked example: ICT software upgrade
Worked Example: Evaluating an ICT Software Upgrade
Consider a business evaluating whether to introduce new ICT software in its sales and marketing department:
| Forces for change | Score (+) | Forces against change | Score (-) |
|---|---|---|---|
| Employees want easier software to save time | 4 | Cost of new software package | 2 |
| Improved workflows | 3 | Need to train staff | 2 |
| Less time to process sales | 2 | System maintenance requirements | 2 |
| Employees can improve skills and productivity | 4 | Resistance to change by some employees | 2 |
| Increased cyber security risk | 1 | ||
| Total | 13 | Total | 9 |
Analysis: The driving forces (total score: ) outweigh the restraining forces (total score: ). This suggests the business should proceed with implementing the new ICT software.
Next steps: The business must now:
- Plan the implementation process carefully
- Address the identified restraining forces (training, costs, resistance)
- Monitor the system after implementation
- Evaluate whether the expected benefits materialise
Exam technique: Using Force Field Analysis
Applying the theory in assessments:
For 'analyse' questions:
- Identify specific driving and restraining forces
- Explain the strength of each force
- Consider the balance between forces
- Link to the likely success or failure of the change
For 'evaluate' questions:
- Weigh up the relative importance of forces
- Consider both short-term and long-term impacts
- Discuss limitations of the model
- Make a judgement about the overall situation
Command word tips:
- Outline: List the key principles and explain them briefly
- Analyse: Break down the forces and examine their impact
- Evaluate: Make a judgement about whether change will succeed based on the balance of forces
Remember!
Key Points to Remember:
- Force Field Analysis is a framework developed by Kurt Lewin in 1969 to help businesses analyse and manage change
- Driving forces push towards change and support the goal, while restraining forces resist and block change
- The four-step process involves: weighting, ranking, implementing and evaluating
- Change is most likely to succeed when driving forces are stronger than restraining forces
- Businesses should use a structured approach: define goals, identify forces, assign scores, implement and monitor
- The model provides a visual and numerical way to assess whether proposed changes should proceed
Key terms:
- Force Field Analysis – a tool for identifying and analysing forces that drive or resist change
- Driving forces – positive pressures supporting movement towards a goal
- Restraining forces – negative pressures preventing or hindering change
- Weighting – assigning numerical scores to indicate force strength
- Ranking – ordering forces by importance
