The Dependable Dependencies Principle - Draft PaperFor over 15 years we have known of design principles to help us manage dependencies in software to limit the impact of making changes. Another consequence of dependencies has been overlooked, namely the relationship between dependencies and risk of failure in our code. The more depended-upon code is, the greater the potential impact of its failure. We should therefore desire that code this is more depended-upon be more reliable. This paper explores the relationship between dependencies and reliability, and proposes a new design principle, with a first attempt at an accompanying set of metrics, to help us limit the impact of failure.
