If applied regularly and systematically, it can provide a kind of safety net for software architects by keeping their software systems in good shape. Research in software engineering should also investigate refactoring for further disciplines, such as refactoring of test plans, documents or development processes, and their interdependencies, to name just a few.Īs the size and complexity of software systems are still increasing, software architecture refactoring is an important tool to manage this complexity. For example, refactoring core assets of a product-line architecture potentially influences all applications, not just one. Refactoring platforms of software product lines leads to additional issues.

Architecture refactoring can also have an impact on implementation, which implies that architecture refactoring and code refactoring are interleaved activities. Some tactics for code refactoring also address architecture design. It is necessary to better investigate the combination and relation between architecture and code refactoring. In addition, interested software engineers could establish a public or company-local catalog. The author of this chapter provides a document that includes a catalog of such architecture refactoring patterns. Martin Lippert and Stefan Roock provide further refactoring examples in their book on refactoring large systems. As a first approach, software architects and developers might leverage the refactoring books by Martin Fowler, Joshua Kerievsky, and Scott Ambler. Currently, such pattern catalogs are not sufficiently available in literature-at least not publicly. The availability of substantial catalogs or even systems of refactoring patterns would provide a sound foundation for architecture refactoring. Using these patterns increases the productivity of software architects, because they can rely on proven practice instead of reinventing the wheel.Īlthough code refactoring has already become a commodity for software development (in contrast to software architecture refactoring), there are still many areas for future research in software architecture refactoring, such as: Refactoring patterns offer proven solutions to recurring refactoring problems. Consequently, refactoring itself requires a systematic process. Some examples of this were introduced in Section 3.12 (e.g., applying an inadequate refactoring pattern that does not consider architecturally relevant quality attributes, such as real-time aspects). Unfortunately, unsystematic refactoring activities can cause more harm than good. Refactoring in general is considered mandatory in TDD. In an agile or iterative/incremental development process, architecture refactoring is an activity that should be conducted at least once per iteration. This way, wrong or inappropriate design decisions can be detected and eliminated early, thus assuring high quality in the software architecture. Consequently, architecture refactoring should become a mandatory process, conducted before or after adding new (major) architecture artifacts to a software system, or when architects identify critical problems.

It is generally applicable when architecture smells are found in an architecture assessment. Software architecture refactoring is an additional activity, which improves the architectural structure of a system without changing its intended semantics.

For this purpose, they should leverage architecture assessment and testing. Software architects are also responsible for keeping the complexity of the existing software architecture small by avoiding accidental complexity. Systematically extending and evolving a software system is only one side of the coin.
