HBRI - Hogan Business Reasoning Inventory Tactical Problem Solving Questions and Answers — Questions and Answers
Question 1: A call center manager starts a shift to find that 3 of the 10 scheduled agents are out sick. Simultaneously, a system alert indicates call volume is 50% higher than average due to a local service outage. The primary goal is to minimize customer wait times. Which of the following is the most effective tactical action for the manager to take first?
- Send an email to senior management detailing the staffing shortage and requesting guidance.
- Re-route all non-urgent calls to an automated voicemail system and reassign the remaining agents to the critical outage queue. (Correct answer)
- Immediately authorize overtime for the next shift to handle the anticipated backlog.
- Begin the process of hiring temporary staff to cover the sick calls.
Correct answer: Re-route all non-urgent calls to an automated voicemail system and reassign the remaining agents to the critical outage queue.
This is the best choice because it directly addresses the two immediate problems (fewer staff, more calls) by prioritizing the most critical issue (the outage) and reallocating existing resources to have the greatest immediate impact on the primary goal of reducing wait times.
Question 2: A team must complete three critical tasks for a product launch: Task A, Task B, and Task C. The dependencies are as follows: 1) Task A must be completed before Task C can begin. 2) Task B must be completed before Task C can begin. 3) Task A and Task B can be worked on simultaneously. Task A takes 4 hours, Task B takes 6 hours, and Task C takes 3 hours. Assuming the team starts all possible tasks at 9:00 AM and works continuously, what is the earliest possible time the entire sequence of tasks can be completed?
- 1:00 PM
- 3:00 PM
- 4:00 PM
- 6:00 PM (Correct answer)
Correct answer: 6:00 PM
This problem requires identifying the critical path. Since Task C depends on both Task A and Task B, it can only begin after the longer of the two prerequisite tasks (Task B) is finished. Tasks A and B both start at 9:00 AM. Task B takes 6 hours, finishing at 3:00 PM. Task C then begins at 3:00 PM and takes 3 hours, resulting in a final completion time of 6:00 PM.
Question 3: A software-as-a-service company notices from their real-time monitoring dashboard that the average API response time has suddenly increased from 200ms to over 1500ms in the last 15 minutes, causing timeouts for many customers. What is the most effective immediate troubleshooting step for the on-call engineering team?
- Draft a message to customers apologizing for the service degradation.
- Provision additional servers to handle what might be an increase in user traffic.
- Check the deployment logs to see if a recent code change or update coincides with the start of the slowdown. (Correct answer)
- Begin a full-scale performance audit of the entire application architecture.
Correct answer: Check the deployment logs to see if a recent code change or update coincides with the start of the slowdown.
When a stable system suddenly exhibits a problem, the most probable cause is a recent change. Checking deployment logs is the fastest way to correlate the start of the issue with a specific event, such as a new code release. This is a crucial first step in tactical root cause analysis before taking other actions.
Question 4: A fast-food restaurant manager is reviewing the drive-thru performance dashboard for the lunch rush. The data shows that the 'Time at Window' is within the target of 90 seconds per car, but the 'Total Wait Time' from ordering to leaving is exceeding the 4-minute target. What is the most logical tactical problem to investigate immediately?
- The payment processing system at the window is too slow.
- The employees staffing the window are not working fast enough.
- There is a bottleneck between the order station and the pickup window, likely in the kitchen. (Correct answer)
- The menu is too complicated, causing customers to order slowly.
Correct answer: There is a bottleneck between the order station and the pickup window, likely in the kitchen.
The data indicates that the final stage of the process (the pickup window) is efficient. The overall delay ('Total Wait Time') must therefore be occurring in the stages before that. This points directly to a bottleneck in the food preparation and assembly area between when an order is placed and when it is ready for pickup.
Question 5: A warehouse uses a specific process for fulfilling high-priority orders: 1) Pick the item from the shelf, 2) Scan the item into the inventory system, 3) Place the item in the designated packing station bin, 4) Generate the shipping label. A manager discovers that several high-priority items are physically at the packing stations but do not have shipping labels and are not registered as ready-to-ship in the system. Based on this outcome, which step in the process was most likely skipped by the warehouse staff?
- Step 1: Pick the item from the shelf.
- Step 3: Place the item in the designated packing station bin.
- Step 4: Generate the shipping label.
- Step 2: Scan the item into the inventory system. (Correct answer)
Correct answer: Step 2: Scan the item into the inventory system.
The evidence shows the items were physically picked (Step 1) and moved to the correct location (Step 3). The problem is that the system is unaware of this progress, preventing the shipping label from being generated (the symptom described in Step 4). Therefore, the most logical failure point is Step 2, the scan that updates the system.
Question 6: A delivery service guarantees same-day delivery. A driver's truck breaks down at 2 PM with 10 packages remaining for delivery. The driver's shift ends at 5 PM, and the company's central warehouse is 30 minutes away. Which of the following options best balances the priorities of fulfilling the delivery guarantee and managing company resources efficiently?
- Wait for the company's standard roadside assistance, which has an estimated arrival time of 2 hours.
- Use a ride-sharing service to take all 10 packages and complete the route, leaving the truck to be dealt with later.
- Contact the nearest driver on a different route to come and pick up half the packages.
- Immediately call the dispatcher to send a replacement vehicle while arranging for the broken-down truck to be towed. (Correct answer)
Correct answer: Immediately call the dispatcher to send a replacement vehicle while arranging for the broken-down truck to be towed.
This is the most comprehensive tactical solution. It addresses the immediate problem (undelivered packages) by getting a replacement vehicle, which is the most reliable way to complete the route and meet the guarantee. It also deals with the secondary problem (the broken truck) and uses the central dispatcher to coordinate efforts efficiently.
