Why Developers Must Understand Product and Business Rules, Not Just Code

A DEV Community article argues that writing code accounts for only 30% of a developer's real work, with the remaining 70% requiring an understanding of product thinking and business rules. The piece defines a digital product not merely as software, but as any solution that delivers genuine value to users by addressing a problem, need, or desire. The author, Renan, emphasizes that technical decisions made by development teams directly affect business outcomes, making product knowledge essential at every career level. The article is the first in a planned series aimed at bridging the gap between development and product management without heavy jargon. It targets developers at all stages, from beginners to seniors, encouraging them to go beyond coding and engage with the broader context of what they build.
