The Product Line Architecture (PLA) of a Software Product Line (SPL) is the core architecture that represents a high-level design for all the products of an SPL, including variation points and variants. If PLA documentation is missing, it can be recovered by reverse engineering the products. The recovered PLA is a relevant asset for developers and...

The architecture of a Software Product Line (or Product Line Architecture, PLA) is one of the most important assets of a Software Product Line (SPL) as it represents an abstraction of all the products that can be generated in an SPL. Furthermore, the PLA is crucial for the development and evolution of an SPL. It represents the architecture of all p...

Software product line (SPL) approach has been widely adopted to achieve systematic reuse in families of software products. Despite its benefits, developing an SPL from scratch requires high up-front investment. Because of that, organizations commonly create product variants with opportunistic reuse approaches (e.g., copy-and-paste or clone-and-own)...

Software Product Line Engineering (SPLE) has been widely adopted for applying systematic reuse in families of systems. Given the high upfront investment required for SPLE adoption, organizations commonly start with more opportunistic reuse approaches (e.g., a single system that they clone and modify). However, maintenance problems appear when manag...

Testing a system is a routine activity, and it plays an important role in the software quality assurance process. However, testing highly-configurable systems, such as Software Product Lines (SPL), is a rather complex activity, due to the presence of variability in its engineering process, which increases the number of product configurations to tes...

Software Product Line (SPL) engineering is a paradigm for the development of a family of products based on the systematic reuse of artifacts. Although its increasing adoption, organizations often start with a single system and use ad-hoc techniques such as clone-and-own to create new systems by performing small changes and adaptations to meet custo...

In software product lines engineering, the products are instantiated by configuring the architecture and customizing components in an asset library. In this context, the Product Line Architecture (PLA) is a key element, as it captures the central design of all products and allows for the expression of variability and commonalities of the product in...

Due to the complexity of managing architectural variability, maintaining the Product Line Architecture (PLA) up-to-date and synchronized with the project source code is a key challenge. Moreover, allow the variability traceability in architectural level of large-scale projects is a costly task. The systematic use of Software Architecture Recovery (...

This poster extend the research presented in the following paper: Product Line Architecture Recovery: An Approach Proposal (Extended Abstract)

The Product Line Architecture (PLA) is an important asset for the success of Software Product Line (SPL) projects. Due to the complexity of managing the architectural variability, maintain the PLA up-to-date and synchronized with the project source code is a hard problem. The systematic use of Software Architecture Recovery (SAR) techniques enables...

The Agile software development stands out mainly for prioritizing functionality development through executable code instead of the extensive written documentation allowing quick responses to changes. Due to this context, this paper aims to report the implementation of the Scrum agile methodology in a classroom environment, with all the project exec...

Product Line Architecture (PLA) design is a key activity for developing successful Software Product Line (SPL) projects. PLA design is a difficult task, mostly due to the complexity of the software systems that SPLs deal with, and their variabilities. Metamodels have been used to support the representation of assets that compose a PLA, SPL variabil...

Agile methodology is designed to ensure an increase in productivity in software development, targeting the availability of a functional software in less time, and organize the processes of planning and development of the software with a risk reduction. Thus, the purpose of this article is to report the experience of using the Scrum agile methodolog...

Over the years, software architecture has become a established discipline, both in academia and industry, and the interest on software architecture documentation has increased. In this context, the improvement of methods, tools, and techniques around architecture documentation is of paramount importance. We conducted a survey with 147 industrial pa...

Context: Over the years, the interest on software architecture recovery has increased. Due to software product line inherent complexity, the recovery of product line architecture is crucial to alleviate difficulties and enable benefits during the SPL development. Objective: In order to gather data and evidence about the relationship between product...

Teaching technical disciplines in computing courses often do not lead the learning efficiently. Consequently, occurs a high number of repetition and dropouts, without a proper learning process monitoring. This paper proposes the use of an educational game for teaching programming language as a way to optimize the process of teaching and learning, u...

Software architecture has become an established discipline in industry. Nevertheless, the available documentation of architecture is often not perceived as adequate by developers. As a foundation for the improvement of methods and tools around architecture documentation, we conducted a survey with 147 industrial participants, investigating their cu...
