Finally!! An exam from the people (NCEES) that do the Professional Engineer licensing exams across different states for software! This is a HUGE step in the right direction for the professionalization of software engineering. My home state, Virginia, is one of the states asking for the exam! Soon, you can be a licensed software engineer, just like a civil engineer.

I am a software developer. I want to increase my knowledge in Engineering field. What is the best step for me now?
Interesting question. I would look at the SWEBOK (just google it) and also read one of the intro books on Soft. Eng. by Pressman.
