How do you maintain product quality as you scale the team rapidly?

Model answerQuality degrades at scale because coordination cost rises faster than output. The solution isn't more process — it's clearer principles. I'd codify what 'good' looks like for this product: a written quality bar that new PMs and engineers can use to self-evaluate. I'd also protect a percentage of each sprint for quality work — if it's not scheduled, it won't happen. And I'd track quality metrics (bug rate, NPS, task completion) alongside velocity metrics.
