Product development as an adaptive walk is a new way to manage uncertainty. Predictions far into the future are highly uncertain. Pulse support short lead time.
Nonlinear systems contain 3 actors or more that interact in a nontrivial way. The actors exchange energy, information, decisions and resources. A nonlinear system is not equal to the sum of its parts , it will always be less or more. A nonlinear system can have sudden changes and threshold transitions, but it can also be very resistant over a long period of time. People that interact in a company will form nonlinear systems internally and with the surrounding market.
