You've got some 'splainin' to do. What's the difference between a
"process" and a "method"? You put "better" in scare quotes, apparently
because you understand that it's a relative concept, but you don't tell
us about what makes "better" better. What are your criteria? Are you
considering only output values? Are there fiscal considerations (i.e.,
given equivalent output, is one process better because it's less
costly)? What, exactly, are you trying to do?
