Paragraphs highlighted in green indicate diagrams or tables that can be shared in the “Case exhibits” section.
Paragraphs highlighted in blue can be verbally communicated to the interviewee.
Paragraphs highlighted in orange indicate hints for you how to guide the interviewee through the case.
The interviewee should perform a back-of-envelope calculation which answers two key questions:
- What is the size of the market?
- Should the firm enter the market?
Suggested Case Structure:
Share Diagram 1 with the candidate if deemed necessary.
I. Market Size
- The population of US is approximately 320 million and the average household size is 2.5. Therefore we can say that there are approximately 125 million households
- We can split these households according to their annual income. Approximately 50% households earn more than and 50% earn less than $80k per year
- Assuming 35% of households earning more than $80k and 15% earning less than $80k are willing to pay for these services, we get 35% of 125/2 households + 15% of 125/2 households =31.25 or approx. 30 million households will buy the annual service
Correct the candidate if he assumes different percentages for willingness to pay of households.
Assume annual cleaning fees of $1600.
- Therefore the market size would be $1600 * 30mn or approximately $50 billion
If asked about competition, provide the following information to the candidate:
- National players - 15% of the market
- Local players - 20% of the market
- Independent individuals - 60-70% of the market
If asked about customers, provide the following information to the candidate:
- Customers of national players usually rate quality over price
- Customers of independent individual cleaners usually give more weight to price than quality
- Customers of local players look at a mix of both quality and price
If asked about profitability, provide the following information to the candidate:
- The national players charge an average price of $60 per cleaning service (4 hour job)
- $10 per hour worth labor costs would be incurred by the client
- Additionally one job requires $5 worth cleaning materials
V. Synergy/Core competency
Provide the following information, if requested
- The household cleaning market is quite similar to the disaster remediation market
- Even though the sales processes are quite different, the client could leverage its contacts and customer ratings in the cleaning market
The market is large and looks attractive; the client also has transferable skills and contacts.
We can do a preliminary margin analysis:
[$60 price] - [4 hours * $10 hourly labor costs] - [$5 cleaning materials costs] = $15
Profit margin = 15/60 or 25% profit margin
Important things to do before entering the market:
- Develop a value proposition to the prospective quality-conscious clients
- Research and anticipate likely competitive reactions
The size of the US household cleaning market is $50 billion; it is large and attractive (25% margin). Therefore the client should enter the market.
