Historically, the tenure of most CEOs, business heads and key functional leaders of the best organisations globally have been short-lived despite these leaders being highly talented with credible academic qualifications, high caliber & proven track records. One common factor that came to light was that they failed at a critical point of business decision. The book has been crafted using well-researched & scientifically-analysed data and successfully introduces a new term in the personality spectrum, i.e., Precast Personality. The book argues that it is the Precast Personality of incumbent that plays a predominant role over Apparent Personality acquired through high profile academic/management courses to suit the assigned role resulting into the failure at “a critical point of business decision”. The book blends Occult Sciences and Psychology to conceptualize & derive a Theory for decoding Personality to achieve Organisational Success. The book ultimately leads to design a Cosmo-Psycho Tool to decode Personality of incumbent. It effectively answers the following questions: a. What is Precast Personality? b. Do occult sciences have scientific bearing? c. Is there a relationship between occult sciences and new age sciences?
