What the interviewer wants: Technical knowledge of EOQ and practical awareness of its limitations in a Nigerian context.
How to structure your answer: Explain the formula, assumptions, and how you adjust for Nigerian realities.
Sample Answer
"The EOQ formula is: EOQ = sqrt((2DS)/H), where D is annual demand, S is ordering cost per order, and H is holding cost per unit per year. For example, if annual demand is 10,000 units, ordering cost is â¦50,000 per order, and holding cost is â¦1,000 per unit per year, the EOQ would be sqrt((2*10,000*50,000)/1,000) = sqrt(1,000,000) = 1,000 units. The formula assumes constant demand, fixed ordering costs, and immediate delivery. In a Nigerian supply chain, these assumptions often do not hold: demand can be seasonal and volatile, ordering costs vary with exchange rates and port charges, and lead times are unpredictable due to port congestion at Apapa. Therefore, I use EOQ as a starting point and adjust based on actual demand variability and lead time data. I also incorporate safety stock to buffer against supply disruptions."
