• Sub-programmes:
    • “self-made”
    • reuse of code = reduction
    • sub-program once refined does not have bugs, thus reusing it is safe
    • code easier to read/understand
    • decreased length
    • Collections
      • reusable
      • provided by third party
      • quicker programming, as less code needs to be written
      • Why needed?
        • reduces length of program
        • easier to read/understand as shorter
          • more organized
  • if a team, people can work on sub-program, while other work on main program
  • easier to debug if divided into parts
