Product design question

How would you improve a coffee machine used in offices?

What this question tests

Product improvement for a shared workplace device, requiring attention to multi-user coordination pain points.

Segment users: casual coffee drinkers wanting quick simple options and enthusiasts wanting quality and customization, sharing one machine.
Identify the pain point: long lines at peak morning hours and inconsistent cup quality from inconsistent maintenance like descaling.
Prioritize the peak-hour queuing problem, the most universally felt frustration regardless of coffee preference.
Propose a solution: a mobile order-ahead feature so employees queue remotely and pick up when ready, cutting in-person wait.
Add a maintenance layer: sensors alerting facilities staff when beans or water run low or descaling is due, keeping quality consistent.
Define success: average wait time at peak hours and reduction in maintenance-related complaint tickets.

Picks queuing at peak hours as the sharpest, most broadly felt pain point rather than a list of flavor features.
Proposes a concrete, realistic fix, mobile order-ahead, that doesn't require new hardware investment.
Adds a maintenance-monitoring layer addressing the less visible but real quality-consistency problem.
Uses wait time and complaint ticket reduction as measurable, low-cost-to-track success metrics.

Suggesting new drink flavors or novelty features without addressing the core queuing frustration.
Ignoring the maintenance and quality-consistency angle.
Not defining a measurable outcome for the improvement.

How would you handle multiple offices with different machine models?
What would you do if order-ahead created a different kind of congestion at pickup?
How would you measure whether this actually improved employee satisfaction?
