You are the EM owning a core workflow in a B2B design platform. A recent performance regression is causing customer-facing delays and support escalations, but the fastest fix would add technical debt and likely slow the team again in the next quarter. A more scalable redesign would reduce long-term risk, but it would take longer and leave some customers with a worse experience in the near term. Your product partner, support lead, and engineering team do not agree on how much short-term pain is acceptable.
Tell me about a time you had to make a trade-off between short-term customer impact and long-term scalability.
