What would you say to your boss if he is crazy about an idea, but you think it stinks?

Before approaching the Boss, I will analyse the problem related to that idea and try to solve the problem. If don't then I'm going to share the drawback problem related to that idea with the Boss. So, that Boss can rethink and try to solve the problem.

I would first acknowledge his suggestion as one way of doing things, then share mine as another alternative citing its strengths and advantages but leave my boss an opportunity to either take my option or incorporate ideas as a blend.

As my strength, I am a good observer. And I have also critical thinking skills so I analyze the things that is in future it will be good for our company or not.

Then, I was concerned about the idea of our boss.

Sir/Mam, I believe I must prioritize the well-being of the company above all. If my boss is passionate about an idea that could potentially harm the company, I feel obligated to respectfully and pragmatically point it out.

I would approach the situation with compassion and care, ensuring that my feedback does not come across as offensive, mocking, or insulting.

My goal would be to highlight the positive aspects of the idea while addressing any concerns in a nuanced and constructive manner.
