ADAPT E.N

Tim Harford's "Adapt: Why Success Always Starts with Failure" is a book about economic case study.
In the book was mention that there are three essential steps for successful adapting:

1. The first is to try new things with the knowledge that some will fail.
2. To make failure survivable since some of the attempts will surely fail.
3. To make sure you know when you have failed.
The essential steps seem fairly straightforward, but Tim Harford takes the reader on a journey through history, recalling many failures - Robert McNamara's handling of the war in Vietnam; Donald Rumsfeld's stubbornness dealing with the war in Iraq; The Piper Alpha rig explosion in the North Sea; and the Lehman Brothers financial meltdown.
In the book, Tim Harford shows how in this world complex the important problems can be resolved only by experimenting and adapting.
For my opinion we don’t always have the luxury to make experiments about our problem. Sometimes the problems are so big that the experiment is impossible. Also they are some decision that should be taken soon and don’t have time to experiment them. This is why people have taken decision hich has been good or bad. But in the end we must learn for by our mistake and prevent our future problems related to them. Also there are problems which have
similar circumstances which are different from the previous problem and the decision is related to this circumstances.
In the end as Tim has claimed in Adapting - improvise rather than plan; fail, learn, and try again.
