Case Details

Boween Pty Ltd is a personal care company, and the key product is liquid hand wash product. The company sells its products both domestically and internationally. Due to the outbreak of the corona virus globally, consumers tend to wash hands more often recently, which lead to a temporary shortage of the product in the market. Thus, the management decided to run the factory into full capacity in order to meet demand in both local and overseas market.

The sales manager has collected overseas sales data for the past 8 weeks, the total selling expensevs. the sales were recorded below. The manager expects the selling expense would be stable at around $23,000 each week in the 2nd quarter and use this as the base assumption to estimate the sales for the foreign business.

The company wants to have a better understanding of how the consumption looks like in the next quarter in Australia, so they did the survey for a sample of 100 target households asking about ‘how many bottles of liquid hand wash would a household consume in the next quarter'. The survey data is attached in the excel. Given that the consumption for liquid hand wash is normally distributed with a standard deviation of 5.

Given the current situation is quite tough, the company also wants the sales department to forecast the sales for the second half of this year. Then the sales department did a scenario analysis as below:
Scenario 1: The outbreak will not get better until the end of the year, so they expect sales will increase by20% in the 2nd half of this year vs. 1sthalf of 2020.

Scenario 2: The market is not getting worse further, sales in the 2nd half of this year will be similar to the 1st half of 2020.

Scenario 3: The vaccine or medicine will be on the market soon and people will return to normal usage level, which is down by -25% in 2nd half compared to the 1st half of 2020.

After the discussion, management thinks the probability of scenario 1 is about 20%, probability of scenario 2 is 30% and probability of scenario 3 is 50%. 1st half of 2020 sales are expected to be AU$20mn.

As a business analyst, however, based on your recent shop visits and the market news, you disagree with the probability of the above. On the back of your findings and analysis of the market, you adjust the probabilities of each scenario and make a new suggestion to the management team.
