Requirements Engineering Track (RET)

The goal of this track is to explore and discuss relevant advances and contributions to the Requirements Engineering field and its relation with different domains of applications, through integrated and robust solutions proposed by researchers and practitioners. This track was previously run as the Workshop on Requirements Engineering.

  • Aligning requirements to business goals and business processes (e.g., goal-oriented requirements engineering)
  • Non-functional requirements
  • Regulatory compliance
  • Requirements elicitation, analysis, and documentation
  • Requirements engineering and software architecture
  • Requirements engineering education and training
  • Requirements engineering for artificial intelligence
  • Requirements engineering for sustainability
  • Requirements engineering for product lines
  • Requirements engineering for specific software development paradigms, such as the agent-oriented, aspect-oriented, or service-oriented ones
  • Requirements engineering for the new generation of software-intensive systems, such as self-adaptive systems, autonomous systems, and cyber-physical systems
  • Requirements engineering for Web-based systems and mobile applications
  • Requirements engineering in agile methodologies
  • Requirements engineering in the context of model-driven development
  • Requirements management, traceability, prioritization, and negotiation
  • Requirements specification languages, methods, processes, and tools
  • Requirements validation and visualization
  • Social, cultural, and cognitive factors in requirements engineering
Technical Papers (not exceeding 14 pages)

Technical Papers (not exceeding 14 pages): Technical papers should describe innovative research in the topics of the main tracks. Papers in this submission category should describe a novel contribution to the topics and should carefully support claims of novelty with citations to the relevant literature.

Evaluation criteria: Technical papers are evaluated by originality, soundness, relevance, importance of contribution, strength of validation, quality of presentation, and appropriate comparison to related work. In case a submission builds upon the previous work of the author(s), the novelty of the new contribution must be described clearly concerning the previous work. Technical papers need to discuss openly how the results were validated.

Emerging Ideas Papers (not exceeding 8 pages)

Emerging ideas papers describe new, non-conventional approaches that depart from standard practice, on the topics of the main tracks. They are intended to describe clear research ideas that are at an early stage of the investigation.

Evaluation criteria: Emerging ideas papers will be assessed primarily on their level of originality and potential for impact on the field regarding promoting innovative thinking. Hence, inadequacies in the state-of-the-art and the pertinence, correctness, and impact of the idea must be described precisely. While the idea that is described does not need to be fully validated, a presentation of preliminary results that provide initial insights into the feasibility and the impact of the idea is expected.


All papers must be submitted through EasyChair (, using PDF format only. Submissions must be formatted according to the LNCS style (

At least one author of each accepted paper must register by the camera-ready deadline. One registration corresponds to only one paper. Some author of each accepted paper must present it in person or the paper will be excluded from the proceedings made available online by Curran Associates (, and later indexed by Scopus. If an author has more than one accepted paper, it is possible to pay the 50% of the registration in the second and following co-authored papers.

Evaluation process

Any paper which is not in the scope of the conference, does not follow the formatting guidelines, or was submitted or published in any other forum (conference or journal) will be desk-rejected without review. All other submissions will be peer-reviewed by at least three members of the Program Committee.

The organizers will publish all accepted papers in the conference proceedings, which will be indexed in Scopus and DBLP.

The best paper of each track will receive an award certificate. Moreover, the three best papers of each track (SET, RET, and ESELAW) will be invited to submit an extended version in English to a special issue of the Journal of Software Engineering Research and Development (JSERD).

Journal first

We are partnering with the Journal of Software Engineering Research and Development (JSERD) to incorporate Journal First papers into the CIbSE 2021 main track. Authors of journal-first papers accepted as Research Articles, Case Studies, or Review in JSERD are invited to present their research work at CIbSE. This offers an opportunity for authors to discuss their work with the community as well as enrich the technical program of CIbSE.

The following evaluation criteria will be used to select journal first papers to CIbSE 2021:

  • The paper describes original results that are not extensions of previous conference papers.
  • The paper was accepted for publication in the journal no earlier than January 1st, 2019.
  • The selected papers will be presented in the technical program of the CIbSE main tracks. At least one author per selected journal first paper will need to register and attend the conference to present it.

Authors interested in presenting journal first papers at CIbSE 2021 should send an email to with the subject “Journal First – CIbSE 2021” by June 1st, 2021. The following information must be provided: (i) paper title; (ii) list of authors; (iii) web link to the paper; and (iv) a short statement on how the work satisfies the criteria above.
