Solve the right problem before sorting the queue
In a case exercise, explaining why information matters may reveal more understanding than guessing a fixed order. Harvard’s case guidance emphasizes clarifying the problem and showing reasoning. This queue is an original simplified exercise, not an employer’s billing, security or support procedure.
At 14:00 you have A (13:40, billing errors affecting 30 orders), B (13:50, information due at 14:20), C (13:55, a possible repeat of A) and D (13:58, an account-data change with no stated deadline). One operations worker and an available lead can be consulted. Resolution time, B’s deadline reason, D’s impact and change authority are unknown.
1. Separate facts from assumptions
| Available fact | Decision-changing question | Risk of assuming |
|---|
| A affects 30 orders. | Is the error still generating charges? Who can investigate and stop its effects? | Treating scale as permission to alter money. |
| B is due at 14:20. | What is the consequence and required effort? | Missing a meaningful deadline or stopping everything for an arbitrary one. |
| C appears to repeat A. | Is it the same incident? Must separate contact and evidence be retained? | Deleting a distinct request or losing a person needing a response. |
| D states no deadline. | Is access, delivery or another urgent consequence involved? | Confusing missing information with lack of urgency. |
A useful opening is: “I want to avoid extending the billing problem and missing confirmed deadlines. Before setting the full sequence, I need to know whether A is ongoing, B’s likely duration and D’s impact.” This states a provisional objective and questions that change the choice.
2. Compare two approaches
Strict arrival order: start A, finish it, then B, C and D. This is easy to justify when requests are comparable and policy requires it. Here impacts differ and A may depend on another team. Waiting for full resolution could let B expire without helping A, and C may duplicate effort.
Triage by impact, deadline and dependency: acknowledge A, alert the lead and identify an authorized owner; associate C only after confirming the relationship; establish B’s effort and consequence; ask about D’s impact. Triage does not override an existing queue policy. It gathers information to apply that policy or request a decision where priorities conflict.
The second approach does not mean solving four things simultaneously. The operations worker has limited capacity. Short contacts, clear owners and identification of the next executable action can help. Someone else can investigate A only if that division of work is confirmed.
3. Change the decision when the scenario changes
Hypothetical variation 1: the lead takes A’s investigation; B needs two minutes, information is available and you are authorized to answer. Handling B during A’s investigation may protect its deadline without interrupting that investigation. Then confirm C’s relationship and D’s impact. Do not silently treat these added facts as guaranteed in the original scenario.
Hypothetical variation 2: A is still causing errors and only you can gather the data requested by the lead; B requires 15 minutes. There is now a real capacity conflict. Explain the consequence of delaying B and request a priority decision or redistribution. “I’ll do everything” does not resolve the constraint. Do not promise to contain A without that authority.
Hypothetical variation 3: D reveals a blocked delivery due in five minutes. Reassess priority with that new impact. This does not make the earlier triage wrong; it shows why missing information needed investigation.
4. End with a checkable answer
A possible summary: “I would not delete C or alter charges on an assumption. I would confirm A’s impact and authorized owner, ask about B’s duration and consequence, and investigate D’s urgency. With A assigned to the lead and B straightforward, I would answer B; if both depended on me, I would make the conflict explicit for a decision. I would record owners, agreed deadlines and required follow-up.”
Check that the answer distinguishes your proposed action, authorization dependencies and missing information. In a real interview, follow the actual exercise’s rules and data rather than forcing this queue onto another problem. The purpose is reasoning that can be discussed and revised, not verbal confidence pretending uncertainty has disappeared.
