Umbrex, Porter Generic Strategies (Cost Leadership, Differentiation, Focus)
The directory entry this score was read from. Umbrex is a consultancy network; its summary is the reference, not a primary source.
It loads no cell and describes no precondition, so it sits outside the canvas. That is a finding about the scope of the canvas, not a judgment of the framework.
Pure market-positioning tool choosing a competitive basis, not a canvas design choice; sits outside the canvas.
This is not a summary of the framework. Umbrex has one; the link under Sources goes there.
Nowhere on the sheet.
