  • Software matures through usage: running in a production environment the smallest remaining bugs will be found over time.
  • Law of continuous change: change will make software progressivity less useful over time until the cost for maintenance is greater than the cost of replacement.

  • Changes introduce more complexity as structure (architecture) will deteriorate over time: unless the structure is changed or complexity is lowered.
