Convinced me to begin with my own checklist while making investment decisions.
The limits of human knowledge has expanded quite drastically, more so in the last century. It is impossible for any man to know everything about a particular field. Be it architecture, medicine, computer science or astronomy. This has lead to specialisations and if that is not enough, super specialisations. Invariably then we need a lot of people to work together to achieve an end. A surgery for example takes a number of doctors, anaesthesiologists, nurses and so on. It becomes imperative to manage information and make sure that people work in a group. It is also very important to keep track of who has done what and if everything important has been done.
In these cases, saying that checklists help is an understatement. Checklists help you get rid of the mundane and concentrate on the important things which require creativity.
I recommend this book very highly.
