title: How do you apply Scrum to maintenance and legacy code improvements?
body: <p>As the title suggest...
  How can I apply a scrum process to anything that doesn't work on new code and can be estimated to some degree?</p>
  
  <p>How can I apply a scrum process to maintenance and emergency fixes (which can take from 5 minutes to 2 weeks to fix) type of environment when I still would like to plan to do things?</p>
  
  <p>Basically, how do I overcome unplanned tasks and tasks that are very difficult to estimate with the scrum process? or am I simply applying the wrong process for this enviroment?</p>
