Lean Software Development

Lean is the concept of developing the easiest solution and doing only what is required and useful. If processes are not adding value, then processes need to change. Lean is a focus on efficiently developing the needed system.

Only document the useful stuff. Know both what is required and who the target audience is for all system and user documentation.

Develop a system anticipating change and code in a way that expects change is coming. Leave options available in anticipating growth of the system and increased usage.
