If noone is taking your business proposals seriously, it may be time to rethink the way you make your presentations. Here are a few tips:

* Be concise - Few managers have the patience or time to listen to someone who rambles.

* Use visuals - A simple graph or table can help you get your point across to people who prefer visual media.

* Offer supporting material - If you have a study or statistics to back up what you have to say, make sure that you have a copy with you.
