Principle #2
Start from existing
practices
Good news, bad news...

9. 16/12/2022 Apidays Paris 2022 - Florimond Manca 8
Ecodesign x Engineering practices
Resource utilization
Performance efficiency
(ISO 25010)
Time behavior
Capacity
Leverage existing tools web.dev, Lighthouse, Yellow Lab Tools...
Rebound effects?
(ISO 14006)

Principle #3
Question the needs
« Do we really need…? »

Principle #4
Beware measurement
bikeshedding
« What one cannot measure, one
cannot improve. »
…Or can we?

Principle #5
Aim for the radical shift
Ascending the gradient of
ecodesign radicalism
