Introduction
Many students enter the CIMA Management Case Study exam with strong technical knowledge but still fail to score well. The issue is not a lack of theory. The real problem is poor application to the case company.
In the May to August 2026 sitting, Cartn presents a complex but highly predictable business model. Students who understand the key traps can significantly improve their performance.
This guide explains five common mistakes and how to avoid them using E2 P2 and F2 thinking.
1 Misunderstanding Packaging Types
Context
Cartn operates in the food packaging industry where primary packaging directly interacts with food and carries safety and regulatory risk
Concept E2
The business model focuses on how value is created and protected. Primary packaging has higher risk exposure than secondary or tertiary packaging.
Application
Students often recommend cost reduction across all packaging types without distinction.
This is dangerous in primary packaging where material interaction can affect product safety and quality.
Exam Angle
The examiner expects clear differentiation between packaging types and awareness of food safety regulations
Recommendation
Always identify the packaging type first
If it is primary packaging prioritize safety compliance and material suitability over cost
2 Ignoring Cartn Dual Business Model
Context
Cartn generates revenue through both manufacturing and consultancy services which create long term client relationships
Concept E2
This reflects ecosystem strategy where value is co created with clients through technical expertise
Application
Many answers focus only on production efficiency and ignore consultancy
Stronger answers explain how consultancy leads to repeat orders and long term contracts
Exam Angle
The examiner is testing strategic understanding not just operational knowledge
Recommendation
Always explain how consultancy strengthens customer relationships and drives future revenue
3 Over Emphasis on Cost Reduction
Context
Packaging decisions involve multiple factors including cost sustainability branding and customer perception
Concept P2
Cost management requires balancing cost drivers with value creation
Application
Students often suggest switching to cheaper materials without considering impact on quality or brand image
Exam Angle
Marks are awarded for balanced analysis that considers both benefits and risks
Recommendation
Structure answers clearly
State cost benefit
Then evaluate risks such as quality sustainability and customer perception
4 Weak Financial Interpretation
Context
Cartn shows strong revenue growth and significant improvement in profitability
Concept F2
Financial analysis requires interpretation of performance not just description of figures
Application
Weak approach
Revenue increased
Strong approach
Revenue growth indicates strong demand and effective conversion of consultancy clients into long term customers
Exam Angle
The examiner rewards insight and business understanding
Recommendation
Always explain what financial changes mean for strategy risk and future performance
5 Ignoring Sustainability
Context
Cartn is investing in sustainable production and reducing environmental impact
Concept E2 and P2
Sustainability links to stakeholder expectations cost management and long term competitiveness
Application
Students often ignore sustainability unless directly mentioned in the requirement
However it is a key industry driver
Exam Angle
The examiner expects awareness of environmental impact and its effect on demand and reputation
Recommendation
Always consider sustainability in your answer even if it is not explicitly required
Pre Seen Application Summary
Cartn operates in a growing global packaging market with strong demand driven by convenience food trends
Its competitive advantage lies in
Consultancy driven sales pipeline

Strong client relationships
Students must reflect these realities in every answer
