I speak with Mary and Ellen about their book Discover to Deliver.  Creating a Structured Conversation about the discovery process.  If you want to build the right thing you need to get people together and explore the space, find the value and find a way to confirm.
They evaluate the dimensions of features along the following dimensions:
<ul>
<li>User</li>
<li>Action</li>
<li>Data  </li>
<li>Control</li>
<li>Interface</li>
<li>Environment</li>
<li>Quality</li>
</ul>

I love the fact that they went for a visual management, lean startup and agile delivery to pull this book together.
