A socio-technical-based process for questionnaire development in requirements elicitation via interviews
Software development is the process of building systems that solve users’ need and satisfy stakeholders’ objectives. Such needs are determined through requirements elicitation, which is considered an intensive, complex, and multi-disciplinary process. Traditional methods of elicitation often fail to uncover requirements that are critical for successful and wide-scale user adoption because these methods primarily focus on the technical aspects and constraints of the systems rather than considering a socio-technical perspective. The success of information system development involves the identification of the social, organizational and technical features of the systems, which in turn can result in a more acceptable system by users. In this paper, we propose a requirements elicitation process based on socio-technical (ST) systems theory. The process leverages ST system components to help identify a set of ST imbalances, which in turn help in requirements elicitation. The applicability of the process is demonstrated using empirical investigation with a randomized two-group experimental design, where the objective is to see the potential of the proposed process to enhance analysts’ understanding of socio-technical aspects of a domain, interview readiness, and questionnaire quality
Dialectic approach to multidisciplinary practice in requirements engineering
This thesis develops an approach that supports multidisciplinary practice in requirements
engineering. It is argued that multidisciplinary requirements engineering practice is
ineffective, and some specific problems for multidisciplinary practice are identified. It is also
suggested that the incommensurability of conflicting paradigms is an underlying cause of the
problems in multidisciplinary practice, and a number of criteria for support to overcome
such problems are proposed.
A form of methodological support, which it is claimed may help overcome some of the
problems associated with multidisciplinary practice in requirements engineering, is
developed. This methodological support takes the form of a dialectic process, and its
associated products, which is conceptualised and then operationalised. As an illustration of
the methodological support offered to multidisciplinary practice, the operationalisation of
the dialectic process is applied to requirements constructed by the use of two different
requirements engineering techniques from two different disciplines (representing two
different paradigms), in the domain of Accident and Emergency healthcare. Finally, the
application of the operationalisation of the dialectic process is assessed with respect to the
criteria for support for multidisciplinary practice proposed earlier, and this assessment is
used to reconceptualise the dialectic process. The limitations of the research are identified,
and possibilities for future work proposed.
This thesis is aimed primarily at the requirements engineering community, and in
particular the practising requirements engineer. It makes two contributions to knowledge
supporting the practices of requirements engineering. First, the thesis contributes two types
of substantive discipline knowledge: an explanation of why multidisciplinary practice in
requirements engineering is problematic; and the proposal of criteria for support to allay the
difficulties of multidisciplinary practice. It is suggested that these criteria might be used in
the development of new types of support to overcomes such difficulties, or in the assessmment
of new requirements engineering techniques that claim to address multidisciplinary practice.
Second, the thesis contributes methodological knowledge in the form of a dialectic
approach that offers a new way of reasoning about requirements engineering. This
methodological knowledge takes two forms: a generic dialectic approach that might be
applied by requirements engineering practitioners to requirements, generated by a wide range
of requirements engineering techniques, representing alternative paradigms; and a
specific instantiation of the dialectic approach using the MUSE method and the Grounded
Theory method, that might be used in its current form by requirements engineering
practitioners to support their own multidisciplinary practice
