title: Definitions for CMMI Requirement Types in TFS2010
body: <p>I've recently been informed that I need to define the requirements for the project I'm working on using TFS and CMMI. Upon writing a new requirement, you must supply a "Requirement Type". My question is, where can I find actual definitions of the different requirement types? Yes, of course I have googled this already and have found some glossaries that are closely aligned, but not perfect.</p>
  
  <p>If any of you out there have experience with CMMI, and can define these types or point to a better source of information, I would be greatly thankful.</p>
  
  <p>To make this easier, the CMMI requirement types are listed (in TFS) as:</p>
  
  <ul>
  <li>Business Objective</li>
  <li>Feature</li>
  <li>Functional</li>
  <li>Interface</li>
  <li>Operational</li>
  <li>Quality of Service</li>
  <li>Safety</li>
  <li>Scenario</li>
  <li>Security</li>
  </ul>
