hmmm abit of abroad question but im going to assume your asking about the pipeline.......

so this is our company's production pipeline

we start out with the concepts for the clients and after approval we move on to do storyboards for the animation.

After that we start with the modelling and texturing and make a small turntable presentations of the models for the clients (just for updates)

we then start on the rigging and animating the required scenes and make a quick previzualization for the client without any proper lighting (could even be playblasts)

then we move on to fx and lighting and after we are all satisfied with what we have we send them to the renderfarm for rendering

we take the rendered frames to a compositing program(we use after effects ) do your basic color corrections add the effects that would take forever to render in maya like motion blur and finally we render the frames as movie and present it to the client

hope you get an insight as to what is needed to do a cg movie

cheers
