 # Thinking People System
 
 A interactive website to better understand the Thinking People System.
+
+## Feature flow
+
+### Push system
+
+When pushing all the feature as fast as possible, we make the assumption that we can deliver in (# step × # features = 150 days) if everything goes well. The fastest a team can do. We overburden but it's for the good cause. We pay everybody to work so if there is someone with nothing to do, we have to make him do something.
+
+### Pull system
+
+We know that we will never reach the best score ever: the push system where everything goes right. But we limit overburden. We know we prefer waiting for next team to be ready before doing some extra work than having stock of feature pre-baked.
+
+### Pull system and daily problem solving
+
+We invest days where we are not productive at all to investigate and learning from our mistake. We know that we will never reach the best score ever and we know that mistakes will reappear. So we take more time to understand and limit rework.
+
+The more the team investigate, the more the team learn and start to be extremely good at problem solving.
