Last year‘s edition of REFSQ, in 2011, featured a new Empirical Track, during which a Live Experiment about Risk-Estimation was conducted. The detailed results of this experiment will be reported at this year’s REFSQ on wednesday. In addition, the Empirical Fair tried to match (1) industrial sites that wanted experiments done with researchers willing to do them and (2) researchers proposing to do particular experiments with industrial sites willing to let the proposed experiments be done at their sites. After the success of last year, we decided to repeat the Empirical Track this year and to expand it. Therefore, we issued a call for the following kinds of submissions:
- Alive Empirical Study: a controlled experiment, requiring no more than 90 minutes, that involves all REFSQ participants who want to participate, and
- Online Questionnaire: an online questionnaire (survey), designed to require no more than 30 minutes, that is promoted at REFSQ and that can be filled out by all interested REFSQ participants, in their spare time at the conference.
The online questionnaires are now available:
- Perception-based Evaluation of a Checklist for Emprirical Research
To know what empirical research practices the participants currently apply, for thepurpose of gaining a better understanding about the usefulness of a checklist forconducting empirical research.
- State of Practice in Requirements Engineering Survey
To gauge how practitioners use theory and best practice put forward by experts (thatis, to what extent are techniques used). Determine how academic research can beimproved based on what is needed in reality. How to facilitate technology transfer intopractice.
- Survey on Requirements Engineering for Variability-intensive Software Systems
Understand what activities requirements engineers perform and what activities areappropriate when dealing with variability in requirements; understand the needs ofpractitioners when dealing with variability in the real world.
- Perception-based Evaluation of a Checklist for Emprirical Research
- Empirical Research Fair Proposal: an empirical study that a researcher would like to conduct in an industrial setting or vice versa.
Alive Empirical Study
The discussion at recent REFSQs have confirmed the strongneed for empirical validation of the effectiveness for our RE methods, but the literature to date, including that of REFSQ, could show more of this validation. This lack is assumed to be at least partly due to the difficulty of finding and persuading the participation of a sufficient number of suitable experimental subjects. Therefore, REFSQ 2012 issued a call that offers an opportunity to conduct an empirical study during the conference itself. The goals of this opportunity, besides that of permitting to conduct the experiment, are to raise awareness for the necessity and benefits of empirical studies and to show that participating in them is not dangerous to one’s health. Furthermore, we want to bring together the community of researchers and practitioners who are interested in empirical studies.
Live Experiment: Do stakeholders understand feature descriptions? Organised by Rumyana Proynova and Barbara Paech, Software Engineering Group, University of Heidelberg, Germany.
This experiment aims to show how well a stakeholder can understand feature descriptions, and whether different forms of feature descriptions lead to different levels of understanding.
Benefits to Participants: The main benefit for the subjects will be new experience and new knowledge. As requirements engineers, they have a preset role in software development projects. By experiencing the role of stakeholders, they will be able to better understand their project partners. Also, due to the real-time evaluation, they will immediately see the feasibility of collecting requirements feedback with questionnaires.
This is a new kind of empirical study in the REFSQ Empirical Track, inspired by submissions we received last year. An online questionnaire (survey) is designed to be filled out by all interested REFSQ participants, in their spare time at the conference (breaks, etc.). It will require no more than 30 minutes to participate.
The following online questionnaires were selected for REFSQ 2012:
- Reliability and Perceived Efficacy of a Checklist for Experimental Reports in Requirements Engineering – Nelly Condori-Fernandez, Maya Daneva
- Requirements Engineering Techniques and Methods: An Online Questionnaire determining actual use in industry - Richard Berntsson Svensson, Tony Gorschek
- A Survey on Requirements Engineering for Variability-intensive Software Systems – Matthias Galster, Paris Avgeriou, Christian Manteuffel
The URLs for accessing the online questionnaire will be provided in the plenary session, on posters at the conference, and on additional sheets in your bag.
Empirical Research Fair
It is clearly understood in the Requirements Engineering (RE) community that case studies of industry projects are critical for our in-depth understanding of both: (a) the phenomena occurring in projects, processes, systems, and services and (b) the impact of our RE methods on the quality, cost, and deliverability of systems. Therefore, in the Empirical Fair, practitioners can propose studies that their organizations would like to have conducted, and researchers can propose studies that they would like to conduct in industry. The Empirical Fair is a meeting point to match the demand and supply of empirical studies among researchers and practitioners. To encourage industry participation, the format of this session is a match-making session in which the authors of the accepted proposals present posters on their intended case studies and the audience can view them and enter a good discussion on the studies goals, benefits, and procedure. Seven proposals have been selected to be presented on posters during the fair. The posters will also be displayed throughout.
