Each company's analysis is a DAG of sorts with assumptions, each assumption based on other assumptions, and all of those based on tables of estimates and projections. That makes it all somewhat unique, at least beyond the industry level. Further, it is not like there are numerous IPOs, its not really done enough times to automate. Finally, there is a hazing and rite-of-passage component to all this. And it is paid very well, with even better prospects after the job, so people accept it.
