With these three skills, I am confident that I can be an asset to your team as a supply planner.”

3. How do you prioritize the different types of inventory you need to manage?

Supply planners need to be able to manage multiple projects at once, so interviewers may ask you this question to see how you prioritize your work. In your answer, explain the steps you take when managing multiple projects and highlight any specific tools or software that helps you with this process.

Example: “When it comes to prioritizing the different types of inventory I need to manage, my approach is to first consider the importance and urgency of each item. For example, if a customer needs an order quickly, then that would take precedence over any other items in the inventory. Next, I look at the cost associated with each item. If there are multiple options for a particular item, I will compare the costs and select the most cost-effective option. Finally, I consider the availability of the item. If one item is more readily available than another, I will prioritize the more accessible item.”

4. What is your process for identifying and eliminating waste in your supply chain?

Waste is a common term in supply chain management. It refers to any activity that does not add value to the company’s bottom line. Interviewers ask this question to see if you can identify waste and eliminate it from your processes. Use examples from previous experience to explain how you would do this.

Example: “My process for identifying and eliminating waste in the supply chain starts with understanding the current state of the supply chain. I analyze data to identify any potential areas of inefficiency or waste, such as overstocking or underutilized resources. Once identified, I work with stakeholders to develop solutions that reduce costs while maintaining product quality.

I also use predictive analytics to anticipate future needs and adjust inventory levels accordingly. This helps me ensure that we have the right amount of stock at the right time without having too much or too little on hand. Finally, I monitor performance metrics to track progress and make adjustments when necessary. By taking a proactive approach to managing the supply chain, I am able to identify and eliminate waste quickly and efficiently.”

5. Provide an example of a time when you had to manage a supply shortage. What actions did you take?

This question can help the interviewer understand how you handle challenges and make decisions under pressure. Use examples from your experience to highlight your critical thinking skills, problem-solving abilities and leadership qualities.

Example: “I recently had to manage a supply shortage at my current job. The situation arose when our supplier failed to deliver the necessary materials on time, leaving us with an unexpected shortfall in our inventory. In response, I quickly identified alternative suppliers who could provide the same materials and negotiated favorable terms for their delivery. I also worked closely with our production team to adjust our production schedule so that we could make up the difference in our inventory levels. Finally, I communicated regularly with all stakeholders throughout the process to ensure everyone was aware of the situation and knew what actions were being taken. Thanks to my quick thinking and proactive approach, we were able to successfully manage the supply shortage without any major disruptions or delays.”

6. If you had to choose one type of inventory to manage, what would it be and why?

This question can help the interviewer assess your attention to detail and ability to resolve issues. Your answer should include steps you would take to identify the discrepancy, how you would report it and what actions you would take to correct it.

Example: “If I noticed a discrepancy in the amount of inventory on hand compared to what was listed in the system, my first step would be to investigate the cause. I would review all relevant documents and records, such as purchase orders, invoices, and shipping manifests, to determine if there were any errors or discrepancies that could explain the difference. If necessary, I would also contact vendors and suppliers to verify the accuracy of their records.

Once I had identified the source of the discrepancy, I would take steps to correct it. This might involve updating the inventory management system with the correct information, issuing a credit for an incorrect shipment, or coordinating with other departments to resolve any issues related to the discrepancy. Finally, I would document the process I used to identify and address the issue so that similar problems can be avoided in the future.”
