Painless documentationPermalink
arc42 users like the understandability, that mainly results from its standardized structure.
But what they really love is the manageable effort it takes to create and maintain arc42-based architecture documentation. We call it “painless documentation”, using the arc42 template does not require additional effort:
- You only describe things that your stakeholders really have to know.
- You explain facts and issues that are necessary to understand the system or individual design decisions.
- You only keep track of important architecture decision that you had to make anyhow.
