How would you frame a major refactoring proposal using product strategy?

WHAT THIS TESTS: The interviewer wants to see if you can escape the classic trap where technical debt is treated as an engineering hygiene issue that the business grudgingly funds. They are looking for product-thinking: can you reframe infrastructure health as a delivery risk and propose an organizational model that prevents debt from falling into the cracks between development and operations.

A GOOD ANSWER COVERS: First, quantify the business impact in product terms. You should explain how technical debt slows feature velocity, increases incident volume, and forces operations teams to fight fires instead of improving systems. Second, diagnose the structural cause. Cite that debt often arises between project funding for innovation and constrained operational budgets, leaving neither dev nor ops with clear accountability. Third, propose the product model as the fix. Advocate for durable cross-functional product teams that own both feature delivery and technical health, eliminating dev-vs-ops politicking over who pays. Fourth, define outcome-based milestones. Instead of promising cleaner code, commit to measurable results like reducing deployment lead time by thirty percent or cutting critical incidents by half within two quarters.

COMMON WRONG ANSWERS: A major red flag is framing refactoring as a purely technical necessity that leadership should trust engineering to fund without business justification. Another is proposing a big-bang IT transformation; Forrester notes these are notorious for failing when used to pay down debt. Avoid suggesting that operations should absorb migration costs out of existing efficiency budgets, as this perpetuates the crack where debt grows.

LIKELY FOLLOW-UPS: The interviewer may ask how you would prioritize which debt to pay first when product wants new features. They might also probe how you would handle a business leader who says the system works fine as-is. Be ready to discuss specific metrics you would track and how you would structure team incentives so that reliability and velocity are not treated as opposing goals.

ONE CONCRETE EXAMPLE: Imagine your platform runs on end-of-life middleware that requires millions in migration costs to maintain the status quo. Instead of asking for a standalone infrastructure project, you frame the proposal as a product initiative: the current stack is delaying a new customer-facing API by three sprints and causing two production outages per month. You request a dedicated product squad with engineering, ops, and product management ownership, funded for one quarter to modernize the middleware. Success is measured not by lines of code rewritten but by API launch date moved up and incident count dropping to zero.
