title: How to measure estimate and story points in Scrum?
body: <p>Lets take an example suppose we got 5 stories A,B and C,D,E.</p>
  
  <pre><code>Importance Name Estimate
  90         B 
  70         A 
  50         C 
  35         E
  10         D 
  </code></pre>
  
  <p>The stories are ordered based on their importance (priority). How do you estimate them? Is it estimated based on the size of the feature? For example I have given them estimate values:</p>
  
  <pre><code>Importance Name Estimate
  90         B     10
  70         A     12 
  50         C     9
  35         E     20  
  10         D     11
  </code></pre>
  
  <p>Let's suppose it is a 2-week sprint. This is 14days time size=5,14x5=70 man-days.
  Now what does the value 10 mean? Does it mean amount of time (hrs or days) a team should spend? And what are story points? Suppose this is the first sprint; how will you estimate the number of sprints when you don't have the last sprint's velocity?</p>
