Typeface designer's procedure


Hey guys,

I was wondering if there is already a thread which describes what font designers do in the process of creating a font. Like whether they sketch or directly make the font in computer? What are their first words? Do they make the whole character set and then adjust spacing and kerning or go incrementally?
If there is no such thread can you list your procedure here.( From conception of the font idea to final shipment of the font)
