title: Which UML diagram should I start with?

  <p>Say you're looking at the 6 basic types of UML diagram (from this The Elements Of UML 2.0 Style)</p>
  
  <ol>
    <li>Class diagrams</li>
    <li>Use case diagrams</li>
    <li>State machine diagrams</li>
  
    <li>Activity diagram</li>
    <li>Sequence diagram</li>
    <li>Physical diagram</li>
  </ol>
  
  <p>Pretend you're insane and you feel like drawing up all 6 diagrams for your system.</p>
  
  <p>Which would you start with?  Then which would you go to?  What's the best order to visit each diagram if you have a <strong>pretty clear</strong> idea of what you want your system to do?</p>
  
  <p>I think you should start with the physical diagram and work your way to class diagram.  Top down, I always say..?  Am I wrong?</p>
