title: What is Critical Path?
body: <p>As a developer, I sometimes come across the term 'Critical Path' in the context of development execution.
  From <a href="http://en.wikipedia.org/wiki/Critical_path_method" rel="noreferrer">wikipedia</a> I know it has to do with identifying the necessary tasks that <em>must</em> be completed in a project.</p>
  
  <p>Is my understanding correct? </p>
  
  <p>What is the best definition of Critical Path you have encountered?
  How would identify the Critical Path when planning a project?</p>
