An anonymous reader writes "I am a systems engineer and this year a project I've been working on has brought in new revenues in the range of 4-5% of the company's total annual revenue. It's a project spearheaded and ran solely by myself. The revenues were never expected to amount to much from management. My role is purely technical in the company, I'm not in sales and there is no commission for my position. I know the tough reality is that I am owed nothing more than my salary and a pat on the back. After pouring many hours outside of my normal work schedule, as well as sweat and tears into this project, what should my expectations be in terms of extra compensation? What is the best way to approach the subject with management? How would you assess value to projects you knew exceeded expectations and directly affected the bottom line?"
