design - Best programming methodology for very fast timeline and little requirements? -

-

what programming methodology custom applications need coded fast , customized? realize lack of requirements problem no matter what. how convince management change practices? next question how people stop writing 5000 line single file programs?

there's more 1 question ask.

  1. fast development 'little' requirements => hacking using scripting language, assuming there small or few requirements, opposed there no stable or explicit requirements yet there tons in future
  2. fast development tons of unstable, or implicit requirements => scrum, xp, etc. focus on prototyping feedback customer wants possible
  3. get management change practices => let project crash possible ;-) seriously, requires more specific on want change. mileage depends of course on how dilbert-like environment is, , how cynical achieving goals.
  4. getting people stop writing 5k lines programs in single file => show them in way problem you, how equally easy write better structured programs, show benefit might have well, , try agree mutually on better practice.
