Folk-wisdom in software engineering suggests that small functions that adhere to the principle of single-responsibility have several advantages over longer, monolithic functions, including improvement in code comprehension. Despite this widespread view, empirical research on the impact of functional decomposition on understanding code is sparse, yet it is central to software development practices.
