Have you ever had to defend the product's feasibility before management?

Yes, I have had to. In such cases, I prepare a detailed analysis: business goals, target audience, competitive analysis, projected profit, and risks. It's important to support arguments with data — metrics, research results, and user feedback. For example, when defending a new feature, I showed how it addresses specific customer pain points and increases retention, which ultimately impacts revenue. This approach helps management see the product's value and make an informed decision.
