I honestly believe the movie Moneyball may have changed the game more than anything else in the last 100 years. Yes there have always been statistics and analytics to some degree but it used to be just one tool in the toolbox to consider instead of actual biblical text like it is now. I think a well run organization is one that will combine the use of analytics and old school scouts that use their eyes. I think it takes both.
Or another approach would be to just just copy the Rays and do what they do. They seem to have the midas touch.
