Uhmmm, it looks interesting, yet, there is something that is missing.

In my understanding, Agile is defined by the capacity of adaptation, not by following a set of rules. And the objective of such adaptation is not to make developers work well, but to ensure that the team has the maximum competitive advantage, by adapting to the user needs.

And yet, here, what I see is a lot of focus on ensuring that developers do what they are told. Yet, although they performed their task perfectly, the result can become useless because it wasn't what the user expected.

So, at least, IMHO, I believe that the key of Agile is to quickly orient the product to what the consumer appreciates, rather than ensuring that the developers do what they are asked.

Or in simple terms, looking for the bugs of the Product team, rather than the ones from the Development team.

Btw, an agile approach based on those "outcomes" (I prefer do not use that word because there is a lot of hype) works best without estimates :-)
