Although architectural smells are one of the most studied type of architectural technical debt, their impact on maintenance effort has not been thoroughly investigated. Studying this impact would help to understand how much technical debt interest is being paid due to the existence of architecture smells and how this interest can be calculated. Thi...

Architectural Technical Debt (ATD) is considered as the most significant type of TD in industrial practice. In this study, we interview 21 software engineers and architects to investigate a specific type of ATD, namely architectural smells (AS). Our goal is to understand the phenomenon of AS better and support practitioners to better manage it and...

Architectural technical debt (TD) is the most significant type of TD in industrial practice. Our goals in this study were to better understand the phenomenon of architectural smells, help practitioners better manage them, and offer relevant support to researchers.

There are numerous commercial tools and research prototypes that offer support for measuring technical debt. However, different tools adopt different terms, metrics, and ways to identify and measure technical debt. These tools offer diverse features, and their popularity / community support varies significantly. Therefore, (a) practitioners face di...

Design patterns are recommended solutions for typical software design problems, with an extensively studied and documented impact on various quality factors. Flaws in design at a higher levels of abstraction are manifested in architectural smells. Some of those smells, similarly to code smells, can reduce the expected advantages of design patterns...

Bad design decisions in software development can progressively affect the internal quality of a software system, causing architecture erosion. Such bad decisions are called Architectural Smells (AS) and should be detected as soon as possible, because their presence heavily hinders the maintainability and evolvability of the software. Many detection...

Architectural smells represent symptoms of problems at architectural level that can negatively impact internal software qualities and lead to architectural debt. Detecting architectural smells and identifying the most critical ones is the key to prioritize refactoring efforts and prevent software architecture erosion. In this paper we focus our att...

With the introduction of microservice architecture, many investigate how to migrate their legacy systems into this architectural paradigm. The migration process requires the recovery of the project architecture to be migrated together with the knowledge necessary to understand how to decompose the code and obtain new microservices. At the moment, t...
