Even with best intentions it can be challenging for people to follow up on actions that they agreed to do. They can start to doubt if they can do the actions and become afraid to fail. Several authors have recognized this and came up with suggestions for dealing with it and making change happen.
At QCon New York 2015, Kolton Andrus discussed Netflix’s Failure Injection Testing (FIT) platform, which allows the injection and monitoring of arbitrary failure scenarios to a targeted group of customers using the Netflix production web services.

Netflix's Failure Injection Testing bridges the gap between isolated testing and unmitigated chaos testing by controlling the impact of the test. FIT establishes a context which other components of Netflix's production testing and infrastructure systems interpret and adjust the behavior of the system accordingly.
To thoroughly remove waste in a process you need flow to deliver just in time, and mindfulness and situational awareness in organizations to handle problems with processes and built in human intelligence.
