Well, I am not an expert but Ill give it a hack.
I have 2 ways I dot things. One is the hectic way.. the other is the precision way.. depends on how much time I have.. how devoted to the project I am.. etc.. I am not a proffessional, and I dont do art for a living.. I did graphic design,web design, and desktop publishing.. but its pretty much the same approach..
1. Figure out what the hell Im concepting for.. *reason* *what it is going to be used for* *who is my target audience* *basic things.. the WHo, what ,when, where, why, and how's*
2. Gather information, references, anything that remotely has to do with what Im working on..
3. Go over the info, familiarize myself with it...
3. Start to develope..(with this comes many things.. For instance if it is just a charecter concept... then I try a bunch of poses.. outfits...etc... do a lot of 3-4 inch thumnails.. then I pick the best one and work it as far as it needs to go... Sometimes I find myself not likeing it, so I go with the runner up...
1.Figure out what Im concepting
2. Do some warmup sketches if I havent done any art that day
3. have at it straight from my mind.
Im not sure exactly what you are looking for, but I hope I could help.
But a good way to look at creative process is just look at it light creating anything else or doing something, for instance, a term paper, or rebuilding your computer cause it crashed and wont boot..
*shrugs* hope I didnt confuse you
