Suppose you are 50 years of age and have achieved sufficient power, money, sex, food, clothes and all materialistic things and now you have to live for another 10 years- still all of us die unsatisfied...
What do you live for???
Guess......
We live for KNOWLEDGE
Deliberately/undeliberately we all strive for knowledge- knowledge of fundamentals of nature ; trying to unearth who modelled the nature, why the world is so what it is, what is right and what is wrong and where do we go after death, who brought us in this world, why only this wife, why friends--- possibly endless questions with only may be 1% of answers today------- trying to find the remaining answers
The Scientists try to find this directly, Historians in their own sense, Marketers by modelling consumer behaviour, housewife in their own way....
What we all are doing is trying to build up a Model of our own working spheres and lives and it is such a complex one that only select few - like Jesus, Buddha, Prophet, Rama and Krishna could do it
If we try to combine all subjects- and all knowledge- probably we are trying to discover Nature.
Here comes the importance of Process i.e if we focus on process and try to improve the process- the model will be more robust and more sure to get the results and thus comes in industrial parlance the words like Six Sigma, TQM and Quality aspects.
Now How to Build the Model- Using Knowledge that is available and also update your knowledge by new learnings from the environment and inner self
