Zachman says we are now busy with Enterprise Physics 101 .. the following are some of his claims / comments made during his presentation:

  • We are focusing on the wrong things – we argue about ‘what is EA’?
  • Enterprises are the most complex systems known to mankind; 
  • We don’t have time to ‘understand’ the complexity of enterprises
  • Moving out of the industrial age to informational age (transitional phase is more or less 40 years)
  • Industrial age: Industrial product e.g. planes etc. Focus was on replacing ‘people’ by machines.
  • Key in the Information age is going to be EA
  • Academic community is not helping EA : Focus should not be on the product (Carr – IT does not matter)
  • Academics are short-term oriented
  • We are implementation dominated – we don’t want to engineer
  • What is an enterprise? Manager, mission, objectives, same game, human endeavour, one strategic group … group
  • Engineering is going on for ever – a different way of life – systems have an ‘end’
  • Why do you do EA: Complexity and change.
  • Architecture value is in the fact that it is : flexible, repeatable,
  • The system is the enterprise!
  • Brooks – programming is manufacturing;


  • Observation: people argue about best practices, tools, repositories, .. miss the principles;
  • Information that is important is owned by private companies;
  • ‘things’ are being done under the umbrella of EA;
