I like the explicit calling out of the 'See' step, but I also assume that, when 
doing a proper experiment, seeing is a necessary part of planning.
The idea in Lean is incremental improvement of the system based on current 
observations.  Basically, you are using the scientific method.  Experimentation 
without observation is not effective, and therefore, you have to see to theorize 
effectively.  You can't run a proper Lean PDCA cycle without seeing.  (This is 
in contrast to using PDCA as an excuse to perform the business process 
re-engineering fad of the moment on your organization, regardless of the need 
for it.)
Also, when writing a proposal (an A3 report in Lean) charts and graphs of 
existing conditions are very much encouraged.  You need hard numbers draw from 
observations to create a graph.  If you try to put a graph in the A3, it 
reinforces the need to see first.
