However, if we’ve been creative and come up with a larger number of trees, it’s best at this stage to do some triage – review the trees and decide which are the most promising (and feasible, given our content).

We typically do this “tree triage” by:

...

• We pick one of Michael’s trees – the one that features user groups at the top level – and rename it from “Michael users” to “tree 1”.
  
  
• Sarah’s tree, which uses broad activities as the top level, is renamed from “Sarah” to “tree 2”.
  
  
• And so on.
  
  

Now that we’ve picked the trees we want to test, we need to flesh them out.

...

• Expanding the tree to include all the sublevels we want to test.
  For most trees, this will be all the sublevels that the eventual website will have. For some trees, however (particularly shopping sites that may have thousands of products), we may decide to test a representative sample of the lower levels.
  For more on how many levels to test, see Which part of the tree? in Chapter 6.
  
  
• Making our labels consistent.
  This is the time to clean up our wording so that we use parallel phrasing (e.g. “For patients”, “For doctors”, etc.) where possible, and stricter terminology (e.g. Are we calling them “cars” or “vehicles”?).
  
  
  

Once we have decided on which trees to test, we also need to make sure that they represent all the content that we plan to include in our website.
