I just stumbled about this
Agile processes promote sustainable development.
The sponsors, developers, and users should be able
to maintain a constant pace indefinitely.
I guess I cannot hide from anybody where this comes from…
But it really has a lot to do with Permaculture Design. Learning from
iterations would just be the next value (if a derived one) of Agile
that fits perfectly.
The big difference being that PDesign not considering software but
hardware it cannot afford the “make to throw it away” approach and
have to study complex relations and behavior much more upfront, which
might lead to a principle like e.g.
At regular intervals, the team reflects on how
to become more effective, then tunes and adjusts
its behavior accordingly. 
Amazing, is it not?
And apologies for the slight OTness of this.
Si tu veux construire un bateau …
Ne rassemble pas des hommes pour aller chercher du bois, préparer des
outils, répartir les tâches, alléger le travail… mais enseigne aux
gens la nostalgie de l’infini de la mer.
If you want to build a ship, don’t herd people together to collect
wood and don’t assign them tasks and work, but rather teach them to
long for the endless immensity of the sea.
