I've noticed an interesting trend lately.  Whenever people talk about Agile development or Scrum they use the two interchangeably.  Like one always means the other, and there is no other Agile process other than Scrum worth mentioning.  Why do I think this is an interesting trend?  According to recent surveys (for example here) Scrum is the most popular Agile process in use today so why not just equate the two words?  It definitely isn't a horrible idea.
