CSC444F'06Evalulation Feedback5 A1 Observations Elegance pays, C is fast: keep it simple Heuristics? Specification is trivial – inputs and outputs Design: don’t do elaborate documentation at first –Sketch it on a napkin: most important for YOU to have a clear idea –Document it properly as nearing completion to avoid rework. Code: –Having a clear design in your head saved LOTS of time
