Agile vs Lean

Hola Enrique. Te recomiendo que leas la guía de práctica ágil. La guía explica ágil contra sus orígenes Lean.

Sorry Wade but that is right is you read about Scrum not about Agile in general. In fact as you know stories like Scrum are related to software file but Agile and Lean were create before that. In fact, the first use of Agile word was in a paper published in the USA in 1985 called "Agile Manufacturing".

Actually Sergio, I am talking about Agile and not about Scrum specifically. By "roots" I am talking about the longer history that led to the development of both Lean and the Agile movements. Therefore I cannot talk about "Agile" in terms of software only, I have to go back decades earlier and consider the lessons learned in other industries, especially the research done in the aerospace industry. Similarly, I cannot talk about modern "Lean" practices without talking about people like Ford or Deming. I've found that it helps to realize how the principles discovered in one industry can be applied to other industries, even though technology has changed a great deal.

These are all too intertwined to separate them in my mind, and I blame smart people like you for showing me how they're all connected.

Sorry if I missunderstood your comment Wade. Just to clarify because english is not my first language the only reason I post a comment when I saw that people said that Agile and Lean are the same (not you) if with the objective to help people to search about and to clarify the differences because the diferences, in my personal opinion and experience, will help people do not fail when tried to use them

I avoid worry about whether something is Lean or Agile; the definitions of both are far to vague. Instead, if something appears to be useful, use it regardless of whether it came from something with Lean in the title or with Agile in the title. In the end, the labels don't matter.
