Exploring Maintainability Assurance Research for Service- and Microservice-Based Systems: Directions and Differences
To ensure sustainable software maintenance and evolution, a diverse set of activities and concepts like metrics, change impact analysis, or antipattern detection can be used. Special maintainability assurance techniques have been proposed for service- and microservice-based systems, but it is difficult to get a comprehensive overview of this publication landscape. We therefore conducted a systematic literature review (SLR) to collect and categorize maintainability assurance approaches for service-oriented architecture (SOA) and microservices. Our search strategy led to the selection of 223 primary studies from 2007 to 2018 which we categorized with a threefold taxonomy: a) architectural (SOA, microservices, both), b) methodical (method or contribution of the study), and c) thematic (maintainability assurance subfield). We discuss the distribution among these categories and present different research directions as well as exemplary studies per thematic category. The primary finding of our SLR is that, while very few approaches have been suggested for microservices so far (24 of 223, ?11%), we identified several thematic categories where existing SOA techniques could be adapted for the maintainability assurance of microservices
Some issues in the 'archaeology' of software evolution
During a software project's lifetime, the software goes through many changes, as components are added, removed and modified to fix bugs and add new features. This paper is intended as a lightweight introduction to some of the issues arising from an `archaeological' investigation of software evolution. We use our own work to look at some of the challenges faced, techniques used, findings obtained, and lessons learnt when measuring and visualising the historical changes that happen during the evolution of software
BIM adoption and implementation for architectural practices
Severe issues about data acquisition and management arise during the design creation and development due to complexity, uncertainty and ambiguity. BIM (Building Information Modelling) is a tool for a team based lean design approach towards improved architectural practice across the supply chain. However, moving from a CAD (Computer Aided Design) approach to BIM (Building Information Modelling) represents a fundamental change for individual disciplines and the construction industry as a whole. Although BIM has been implemented by large practices, it is not widely used by SMEs (Small and Medium Sized Enterprises).
Purpose: This paper aims to present a systematic approach for BIM implementation for Architectural SMEs at the organizational level
Design/Methodology/Approach: The research is undertaken through a KTP (Knowledge transfer Partnership) project between the University of Salford and John McCall Architects (JMA) a SME based in Liverpool. The overall aim of the KTP is to develop lean design practice through BIM adoption. The BIM implementation approach uses a socio-technical view which does not only consider the implementation of technology but also considers the socio-cultural environment that provides the context for its implementation. The action research oriented qualitative and quantitative research is used for discovery, comparison, and experimentation as it provides �learning by doing�.
Findings: The strategic approach to BIM adoption incorporated people, process and technology equally and led to capacity building through the improvements in process, technological infrastructure and upskilling of JMA staff to attain efficiency gains and competitive advantages.
Originality/Value: This paper introduces a systematic approach for BIM adoption based on the action research philosophy and demonstrates a roadmap for BIM adoption at the operational level for SME companie

The Centellesâ Palace of Oliva: The Recovery of Architectural Heritage through Its Plundering
At the beginning of the 20th century, the Danish architects Egil Fischer and Vilhelm Lauritzen carried out a rigorous graphic documentary study of one of the most important late-GothicâRenaissance palaces in the Kingdom of Valencia, the Centellesâ Palace of Oliva, with the aim of later taking many of its architectural elements to Denmark. After numerous complaints, the Palace was declared a National Monument in 1920 and the exportation of its pieces was suspended. In 1932, due to heavy rain, a part of the Palace collapsed. The Spanish Civil War increased the deterioration of the Palace, and after some attempts to retrieve it, the remains of the Palace were demolished in the 1950s, and all traces of this large building disappeared with them. Thanks to the graphic documentation carried out by Danish architects, today we are able to know and study this Palace of great cultural and patrimonial interest, which has now almost completely disappeared. The work carried out by these architects, far from destroying the Palace, has helped to preserve it through this graphic legacy which allows us to carry out a highly detailed graphical restoration of many of its elements, as well as a hypothetical physical restitution of them
Mining Architectural Information: A Systematic Mapping Study
Context: Mining Software Repositories (MSR) has become an essential activity
in software development. Mining architectural information to support
architecting activities, such as architecture understanding and recovery, has
received a significant attention in recent years. However, there is an absence
of a comprehensive understanding of the state of research on mining
architectural information. Objective: This work aims to identify, analyze, and
synthesize the literature on mining architectural information in software
repositories in terms of architectural information and sources mined,
architecting activities supported, approaches and tools used, and challenges
faced. Method: A Systematic Mapping Study (SMS) has been conducted on the
literature published between January 2006 and November 2021. Results: Of the 79
primary studies finally selected, 8 categories of architectural information
have been mined, among which architectural description is the most mined
architectural information; 12 architecting activities can be supported by the
mined architectural information, among which architecture understanding is the
most supported activity; 81 approaches and 52 tools were proposed and employed
in mining architectural information; and 4 types of challenges in mining
architectural information were identified. Conclusions: This SMS provides
researchers with promising future directions and help practitioners be aware of
what approaches and tools can be used to mine what architectural information
from what sources to support various architecting activities.Comment: 68 pages, 5 images, 15 tables, Manuscript submitted to a Journal
