As a maintenance engineer in a continuous running plant, I had to face sudden stoppages of continuous running machines due to mechanical defects. I had to answer the management for the consequent losses to the company. My people would tell me that the machine was running fine yesterday or a little while back and it failed suddenly. They claim they could not have detected and prevented the failure.
This could apply to many aspects of life – sudden burst of reactions of people, sudden crisis of some kind etc. We ignore the preceding occurances or symptoms and underestimate their significance. These accumulate over a period of time and one day result in a (sudden?) failure of some kind.
If we keenly observe what is happening around us in things and people and know what is a normal and healthy situation and what is a deviation from it, we can predict where this gradual negative change will ultimately lead to and what could be it’s consequences.
If we take corrective actions in the early stages when we see the adverse movements taking place, the adverse event can be aborted. The so called sudden developments can only happen when we close our eyes to what is happening gradually or choose to ignore or underestimate their significance.
