title: Software Development Costs Pyramid
body: <p>A friend was telling me the other day that there is a pyramid for the costs of fixing a problem in the software development life cycle.  Where could I find this?</p>
  <p>He was referring to the cost of fixing a problem.</p>
  <p>For example,</p>
  <blockquote>
  <p>To fix a problem at the requirements stage costs 1.</p>
  <p>To fix a problem at the development stage costs 10.</p>
  <p>To fix a problem at the testing stage costs 100</p>
  <p>To fix a problem at the production stage costs 1000.</p>
  </blockquote>
  <p>(These numbers are just examples)</p>
  <p>I would be interested in seeing more about this if anyone has references.</p>
