All processes have a rhythm, made up of the individual process steps, their sequence and the time allotted to them. Processes do not exist in a vacuum, however. Every process and its rhythm is subject to external factors.
Germans do their best to prevent external factors from influencing the rhythm of their processes, however. They believe that if a given decision making process has proven to be effective, if it has led to good decisions, it should not be interrupted or distracted.
If the decision is an important one, if the decision making process has proven to be robust, Germans will do their best to shield it from external factors.
