真正的强队，永远有 B 计划（顶级团队，永远不止一套方案）

Responding to a Chinese quote

I see the user shared a quote that translates to "A truly strong team always has a Plan B." I want to agree and provide practical guidance on creating a Plan B in areas like engineering and operations, focusing on contingency planning and risk management.

I’ll keep my response concise with structured bullet points: feature flags, circuit breakers, rollback strategies, and other frameworks like pre-mortem and FMEA. I could also offer a template for a "B 计划清单".Creating a B Plan Checklist

I want to craft a helpful response that includes a title header and offers a checklist template or incident drill script. This will showcase actionable items in simplified Chinese. I’m thinking about incorporating code-related tactics like feature flags, retries with backoff, and caching fallback.

Moreover, I’ll outline key elements for the B Plan, such as triggers, decision owners, playbook links, rollback steps, communication metrics, timeboxes, and exit criteria. This response should be concise and clear for the user.
