参考回答
What the interviewer wants: Sophistication in performance measurement relevant to the industry. They want to see that you use a balanced set of metrics and understand the story behind each number.
How to structure your answer: Group your KPIs by dimension — efficiency, quality, safety, cost, and people — then explain why you prioritize certain metrics and how you use them to drive decisions.
Sample Answer
"I use a balanced scorecard approach organized around five dimensions. For productivity and efficiency, I track Overall Equipment Effectiveness, units produced per labour hour, and on-time delivery rate. For quality, I monitor first-pass yield, customer complaint rate, and cost of poor quality. For safety, I track lost time injury frequency rate, near-miss reporting rate, and percentage of safety audits completed on schedule. For cost, I measure cost per unit produced, maintenance cost as a percentage of asset replacement value, and energy cost per unit. For people, I track absenteeism rate, overtime percentage, and training completion rate. The key is not just collecting data but using it during daily production meetings, weekly operations reviews, and monthly leadership sessions to identify trends and trigger interventions early. In Nigeria specifically, I also track generator uptime and the cost premium for generator power relative to grid power, because utilities management is a material driver of operational cost."
