  in a controlled way
• The architecture process is as important as the
  architecture products

• This results in
• More mature architecture practice
• Better Business IT alignment
• Better architecture project alignment
• More agility

  thing
• Architecture can be much more effective
• With the right measures
• At the right moment

11
Four pitfalls

• Consists of a comprehensive vision backed by
  tangible tools
• Offers a step by step approach
• Practical
• Offers solutions for commonly recognized problems
  and barriers
• Is based on best practices
• Makes a difficult topic understandable
• Free
• Is not proprietary
• Is accessible via books and website
