ProHub Comment

This case teaches candidates to identify the root causes of profitability decline by analyzing financial statements and expense breakdowns systematically. The interviewer deliberately constrains certain solutions (marketing and maintenance) to test whether candidates can synthesize multiple perspectives and trade-offs. The case emphasizes the importance of focusing on quantifiable cost drivers rather than pursuing high-impact but restricted options.

Sardine Airlines, an ultra low-cost carrier, faces declining profitability despite revenue growth. SG&A costs have increased from 15% to 20% of revenue, driven primarily by marketing, customer service, and rent. The solution involves relocating headquarters to a lower-cost market and transitioning to an overseas call center to achieve the CEO’s 20% profit margin target.

Key Insights:

  1. Root cause analysis of profitability decline: Identify that SG&A as a proportion of revenue increased from 15% to 20%, making it the primary driver of declining profit
  2. Constraint navigation: Recognize that some cost reduction options (marketing, seat sizes, maintenance) are off-limits and focus on viable alternatives
  3. Quantitative precision: Calculate specific cost savings ($34.4M from rent, $38.4M from customer service) to reach the $57.6M profit increase needed for 20% margin
  4. Strategic trade-offs: Balance operational efficiency with service quality and regulatory compliance (maintenance must stay optimized for FAA compliance)
