Explain a bit more

It was unpopular—we had already invested weeks of effort—but I took it to leadership, explained the risks, and proposed a re-architecture plan. It delayed the release but saved us from massive rework later. It taught me that doing the right thing technically sometimes means pushing back, even when it’s uncomfortable.

Real-world example (ShopNest)

Managers care that you communicate early, protect quality, and help the ShopNest team deliver predictably.
