<p>The most common approach to dealing with both architectural mismatch and the changing of requirements over time is <b>refactoring</b>, which means changing the <em>architecture</em> of an implementation without changing its behavior. Refactoring is something most developers do as part of changing a system (<a href="#murphyhill">Murphy-Hill et al 2009</a>, <a href="#silva">Silva et al. 2016</a>). Refactoring code to eliminate mismatch and technical debt can simplify change in the future, saving time (<a href="#ng">Ng et al. 2006</a>) and prevent future defects (<a href="#kim">Kim et al. 2012</a>).
<p>Research on the actual activity of software architecture is actually somewhat sparse. One of the more recent syntheses of this work is Petre et al.'s book, <em>Software Design Decoded</em> (<a href="#petre2">Petre et al. 2016</a>), which distills many of the practices and skills of software design into a set of succinct ideas. For example, the book states, "<em>Every design problem has multiple, if not infinite, ways of solving it. Experts strongly prefer simpler solutions over complex ones, for they know that such solutions are easier to understand and change in the future.</em>" These ideas, while powerful in their conciseness, are also grounded in substantial research on how software architects think and work.</p>
