Lean Startup Build-Measure-Learn loop

Eric Ries, 2011
The origin of the framework, as the directory records it. The mark grades the origin, not this page.
Umbrex, Lean Startup Build-Measure-Learn loop
The directory entry this score was read from. Umbrex is a consultancy network; its summary is the reference, not a primary source.
Scored against the twelve cells, it loads one: Learning. The other eleven it leaves to you. None of Composition, Evidence, or Mastery is among them, which is the usual result in this directory: the questions an agent in the loop raises first are the ones the literature answers least.
This is not a summary of the framework. Umbrex has one; the link under Sources goes there.
