Then, make a concise, logical case for your approach: "Emphasize the positive outcome. Focus on what your boss will get out of doing as you suggest." If you've already tried this, keep at it: "Rehearse your argument beforehand and make sure you are stating it clearly and rationally" -- and without a trace of condescension for his (alleged) lack of technical knowledge. Sometimes, of course, it's not what you say that can trip you up, it's how you say it.
然后，找出简洁的、符合逻辑的理由来证明你的方法：“强调积极的结果。把重点放在按照你说的做他能获得什么这一点上。”如果你已经做过类似尝试，坚持下去：“事先预演你的论据，并且你要保证，以一种清晰、理性地方式进行陈述”——不要自以为他在技术上懂得没你多，就表现出哪怕是一丝一毫的傲慢态度。有时候，问题并不在于你说的话，而是你说话的方式。
