The phrase “by-the-numbers” is a common idiom used in English language to describe something that is done in a predictable, formulaic manner. This expression has its roots in the world of entertainment, specifically in the film industry.

To ensure that these films would be profitable, studios developed a system for creating them called “the numbers.” This system involved using market research to determine what audiences wanted to see in a movie, then creating a script that included those elements. The resulting film was then produced quickly and cheaply, with little attention paid to artistic merit.

As time went on, the term “by-the-numbers” came to be associated with any creative work that lacked originality or inspiration. Today, it is commonly used to describe anything from music albums to business strategies that are seen as unoriginal or uninspired.
