Abstract: Groups of architecturally connected files may incur and accumulate high maintenance costs as architectural debts. To quantify such debts, architectural debt, which is a term used herein, may be identified, quantified, measured, and modeled. A history coupling probability matrix for this purpose may search for architecture debts through the lens of 4 patterns of prototypical architectural flaws shown to correlate with reduced software quality. Further, a new architecture maintainability metric—Decoupling Level (DL)—measures how well the software can be decoupled into small and independently replaceable modules. The DL metric opens the possibility of quantitatively comparing maintainability between different projects, as well as monitoring architecture decay throughout software evolution.
