What are patterns?

• A way of capturing good design practice
• A way of developing a common design vocabulary
• Structured around problems designers face
• Each pattern describes a problem which occurs
  over and over again in our environment, and then
  describes the core of the solution to that
  problem, in such a way that you can use this
  solution a million times over, without ever doing
  it the same way twice
• Not created or invented, but harvested
• A pattern language is composed of patterns in
  relationship to each other
