My favorite chapter in this book reviews the cookbook you need to create actionable instructions. The author - who claims to be the one who coined the term "information architecture -- says that too often instructions fail us and even the most careful users make mistakes and become frustrated. So true!

His solution is to follow a formula and make sure you include all the elements on his list for actionable instructions:

• Purpose (Reason)
  
• Objective (Location)
  
• Core (Procedure)
  
• Time (Duration)
  
• Expectation (Anticipation)
• Failure (Error)
