I found a very interesting statement on Crouch, touch, pause…engage.
The technical practices of XP give [teams] a sustained productivity increase, while Scrum practices give a quick productivity boost and then level off.
Knowing that we have again two very famous person of the agile community in front of us. We need to realize that we have another attempt to understand that XP will bring more “sustained productivity.”
I wonder why? Is there a movement against Scrum arising from the agile empire! Now as it starts to realize it is already fallen apart?
I mean to mention that XP gives you the right engineering practices you should follow, is something every Scrum coach on the planet has told everybody since he/she started doing Scrum.
