This inquiry pertains to a business estimation challenge, commonly referred to as a guesstimate question. It evaluates your critical thinking, ability to make assumptions, and problem-solving capabilities. The objective is to gauge how you navigate uncertainty, your capacity for making logical estimates, the assumptions you are willing to adopt, and your skill in deconstructing complex issues into smaller, more manageable components. To tackle this question: Identify your target audiences: Begin by determining who the potential purchasers of face masks are. This group may include general consumers, healthcare facilities, or businesses. Estimate the population: Research population data or industry statistics to gauge the size of your target audience. Determine the usage rate: Estimate the number of face masks that each individual in your target audience may use over a specified period. Add contingency: Include a buffer to account for uncertainties in your estimates.
