What's (X/Y) expansion in errors?

The (X/Y) expansion in errors refers to the increase in errors or mistakes that occur as a result of expanding or scaling up a process or system. This expansion in errors can occur when a process that was previously working well on a small scale is expanded to a larger scale, leading to new challenges and potential sources of error. It is important to anticipate and address these potential errors when scaling up a process to ensure its success.
