- Model-Driven Development (MDD) is no longer a novel development paradigm. It has become mature from a research perspective and recent studies show its adoption in industry. Still, some issues remain a challenge. Among them, we are interested in the treatment of non-functional requirements (NFRs) in MDD processes. Very few MDD approaches have been reported to deal with NFRs (and they do it in a limited way). However, it is clear that NFRs need to be considered somehow in the final product of the MDD process. To better understand how NFRs are integrated into the existing MDD approaches, we have initiated the NFR4MDD project, a multi-national empirical study, based on interviews with companies working on MDD projects. Our project aims at surveying the state of the practice for this topic. In this paper, we summarize our research protocol and present the current status of our study. The discussion will focus on the peculiarities of our study's context and organization involving about 20 researchers from 8 European countries.

Selecting creativity techniques for creative requirements: An evaluation of four techniques using creativity workshops
- 2015

- Requirements engineering is recognized as a creative process where stakeholders jointly discover new creative ideas for innovative and novel products that eventually are expressed as requirements. This paper evaluates four different creativity techniques, namely Hall of Fame, Constraint Removal, Brainstorming, and Idea Box, using creativity workshops with students and industry practitioners. In total, 34 creativity workshops were conducted with 90 students from two universities, and 86 industrial practitioners from six companies. The results from this study indicate that Brainstorming can generate by far the most ideas, while Hall of Fame generates most creative ideas. Idea Box generates the least number of ideas, and the least number of creative ideas. Finally, Hall of Fame was the technique that led to the most number of requirements that was included in future releases of the products. © 2015 IEEE.

Technology Transfer - Requirements Engineering Research to Industrial Practice An Open (Ended) Debate
- 2015

Konferensbidrag (refereegranskat)abstract
- Technology and knowledge have been recognized as main sources of competitive advantage of corporations, industries and nations, particularly in the software domain. They have led to the creation of local ecosystems devoted to development and transfer activities, which ensure not only personal and institutional motivation/recognition, but also social and economic gains. An open (ended) debate panel is proposed in order to develop greater awareness and seek deeper understanding of such activities from Requirements Engineering research to industrial practice. The panel involves researchers and practitioners with the perspective of eliciting: (i) experiences in knowledge and technology development and transfer; (ii) awareness and effectiveness of models and patterns; and (iii) factors for having successful collaboration between research institutions and industry. The organizers also plan to run a survey during and after the conference, summarizing their conclusions in specific post-conference reports.

- The automotive industry is currently going through an enormous change, transitioning from being pure hardware and mechanical companies to becoming more software focused. Currently, software development is embedded into a V-Model process that defines how software requirements are extracted from system requirements. In recent years, OEMs have come to recognize the importance and opportunities offered by software, which include better management and shorter time-to-market of distinguishing features. Strategies to better utilize software include in-house software development and new ways to collaborate with suppliers. However, in their effort to take advantage of these opportunities, engineers struggle with the formal process imposed on software development. In this paper, we investigate the impact of this struggle on the flow of requirements, including challenges and practices. We found that new ways of working with requirements had emerged that are partly not supported, partly hindered by the old tooling and processes for requirements engineering. Requirements flow both vertical and horizontal in the organization and across the supply-chain. Support for the new way of working should allow us to refine requirements iteratively throughout their life-cycle, handle the discussion of rationales, and to manage assumptions. We found strategies of achieving this to differ not only between OEMs, but also between different divisions inside the OEMs.

Challenges of Requirements Engineering in AUTOSAR Ecosystems
- 2015

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- AUTOSAR has changed significantly how software is developed in the automotive sector. As a central standard, AUTOSAR enables reuse of software components as well as their interoperability. For AUTOSAR compliant ECU development, car manufacturers source Electronic Control Units (ECUs) from Tier-1 suppliers, but ask those Tier-1 suppliers to install AUTOSAR compliant basic software from a certified AUTOSAR-Tier-2 supplier. In this setup (to which we refer as the AUTOSAR ecosystem), the OEM has a direct business relationship with the Tier-1, but only an indirect relationship to the AUTOSAR-Tier-2 supplier, which leads to complex flows of requirements and related information between the organizations involved. In this extended abstract, we summarize preliminary results of a qualitative investigation of Requirements Engineering challenges in the AUTOSAR ecosystem. In particular, we interviewed 7 project managers from an AUTOSAR-Tier-2 supplier, and triangulated our results with 6 additional interviews with subjects from two Tier-1 suppliers and one OEM. We found that most of the requirements towards the AUTOSAR-Tier-2 supplier can be directly mapped to standard AUTOSAR components. However, a significant amount of requirements were new requirements and specific to the OEM or even a project. The well-known requirements engineering challenges we found to surface in the AUTOSAR ecosystem were mainly connected to these non-standard requirements. Standard and non-standard requirements are usually mixed, which makes it hard to fully leverage the potential benefits of reuse within the AUTOSAR standard. We argue that the holistic ecosystem perspective allows exploration of new strategies for mitigating this challenge.

An Environment-Driven Ontological Approach to Requirements Elicitation for Safety-Critical Systems
- 2015

Ingår i: 23rd IEEE International Requirements Engineering Conference RE'15. - 9781467369053 ; , s. 247-251

Konferensbidrag (refereegranskat)abstract
- The environment, where a safety critical system (SCS) operates, is an important source from which safety requirements of the SCS can originate. By treating the system under construction as a black box, the environment is typically documented as a number of assumptions, based on which a set of environmental safety requirements will be elicited. However, it is not a trivial task in practice to capture the environmental assumptions to elicit safety requirements. The lack of certain assumptions or too strict assumptions will either result in incomplete environmental safety requirements or waste many efforts on eliciting incorrect requirements. Moreover, the variety of operating environment for an SCS will further complicate the task, since the captured assumptions are at risk of invalidity, and consequently the elicited requirements need to be revisited to ensure safety has not been compromised by the change. This short paper presents an on-going work aiming to 1) systematically organize the knowledge of system operating environment and, 2) facilitate the elicitation of environmental safety requirements. We propose an ontological approach to achieve the objectives. In particular, we utilize conceptual ontologies to organize the environment knowledge in terms of relevant environment concepts, relations among them and axioms. Environmental assumptions are captured by instantiating the environment ontology. An ontological reasoning mechanism is also provided to support elicitation of safety requirements from the captured assumptions.
