Evaluation Framework for Analyzing the Applicability of Criteria Lists for the Selection of Requirements Management Tools Supporting Distributed Coll…
2016
Effective requirements management and enabling tools are critical for successfully developing and maintaining services and products. The identification and selection of an appropriate requirements management tool can be a costly, time-consuming, and error-prone undertaking especially in the context of software product line requirements management, requiring the tools to support both product and platform development activities that often involve geographically distributed, collaborating, and competing stakeholders. Criteria lists have been developed to facilitate the selection. This research (1) creates an evaluation framework to review the applicability of the lists for the selection of req…
Evaluating Bug-Fixing in Software Product Lines
2016
[Background] Bug-fixing could be complex in industrial practice since thousands of products share features in their configuration. Despite the importance and complexity of bug-fixing, there is still a lack of empirical data about the difficulties found in industrial Software Product Lines (SPLs). [Aims] This paper aims to evaluate engineers' performance fixing errors and propagating the fixes to other configured products in the context of an industrial SPL. [Method] We designed and conducted an empirical study to collect data with regard to bug-fixing tasks within the context of a Induction Hob SPL in the BSH group, the largest manufacturer of home appliances in Europe. [Results] We found t…
Comprehensive System for Systematic Case-Driven Software Reuse
2010
Reuse of software artifacts (blueprints and code) is normally associated with organising a systematic reuse framework most often constructed for a specific problem domain. In this paper we present a system (language, tool, reuse process) where software reuse is based on building and retrieving of so-called software cases (large compound artifacts) that can be reused between domains. The system is opportunistic in that software cases result from usual (non-reuse oriented) activities where also semantic information is added. This information is used to support regular development but may serve later to retrieve software cases. Having this common semantic basis, we can organise a systematic cr…
Conquering Fine-Grained Blends of Design Patterns
2008
The reuse of design patterns in realistic software systems is often a result of blending multiple pattern elements together rather than instantiating them in an isolated manner. The explicit description of pattern compositions is the key for (i) documenting the structure and the behavior of blended patterns and, (ii) more importantly, supporting the reuse of composite patterns across different software projects. In this context, this paper proposes a fine-grained composition language for describing varying blends of design patterns based on their structural and behavioural semantics. The reusability and expressiveness of the proposed language are assessed through its application to 32 compo…
Standards Initiatives for Software Product Line Engineering and Management within the International Organization for Standardization
2010
Software product line engineering is an established methodology for fast and effective development of software-intensive systems and services. To reap maximum benefits from the methodology, businesses typically need to implement coordinated changes in development methodologies, tools, product architectures, organizational designs, and business models. Product lines are developed in complex international software ecosystems, but there is no coordinated set of international standards for defining and leveraging the methodology. As a result, ecosystems cannot adopt standardized methods and tools for developing product lines, tool vendors face difficulties in developing tools to enable product …
ISO Initiatives on Software Product Line Engineering: Vision and Current Status Invited Talk for Variability@ER2011
2011
Software product line engineering and management is still a relatively young discipline and its industrial diffusion is somewhat limited, partly due to the lack of international standards. It involves sub-disciplines that may not necessarily be mature enough yet for standardization. On the other hand, well-focused standardization efforts contribute to the diffusion of best product line practices and help raise the maturity of these practices. Careful roadmapping and execution of the standardization initiative is thus vital. This talk discusses the current roadmap for the international standardization initiative of software product line engineering and management methods and tools and the st…
Exploring the Context of Product Line Adoption
2003
To successfully adopt a product line approach an organization needs to define its adoption goals, conceive a strategy, and implement a plan to achieve those goals. This process is repeated for each business unit and individual affected by the product line adoption. This paper describes how the characteristics of the market, organization, business unit, and individual influence product line adoption goals, strategies, and plans.
An inductive learning perspective on automated generation of feature models from given product specifications
2018
For explicit representation of commonality and variability of a product line, a feature model is mostly used. An open question is how a feature model can be inductively learned in an automated way from a limited number of given product specifications in terms of features.We propose to address this problem through machine learning, more precisely inductive generalization from examples. However, no counter-examples are assumed to exist. Basically, a feature model needs to be complete with respect to all the given example specifications. First results indicate the feasibility of this approach, even for generating hierarchies, but many open challenges remain.
Producing Routing Systems Flexibly Using a VRP Metamodel and a Software Product Line
2012
Routing problems occur in a wide variety of situations. Due to the heterogeneity of cases we do not yet know how to manage the complexity of addressing all the relevant aspects in logistic planning and solving the variety of different problem types in a cost-efficient way. In the last decade, we have witnessed an emergence of systematic approach into managing variation within a set of related software systems. This paper presents an application of these advances from software engineering into vehicle routing: we suggest the construction of a higher-level (meta-) model of routing problems and the application of a software product line approach. The proposed approach results in a flexible pro…
The four types of self-adaptive systems: A metamodel
2017
The basic ideas of self-adaptive systems are not a novelty in computer science. There are plenty of systems that are able of monitoring their operative context to take run-time decisions. However, more recently a new research discipline is trying to provide a common framework for collecting theory, methods, middlewares, algorithms and tools for engineering such software systems. The aim is to collect and classify existing approaches, coming from many different research areas. The objective of this work is providing a unified metamodel for describing the various categories of adaptation.
