| Summary: | The discipline of Requirements Engineering (RE) is hard for students to understand and
challenging for lecturers to teach due to its complex nature. In the literature, researchers
have presented a number of Requirements Engineering Education (REE) problems in
universities, as well as RE problems in the industry, which can be addressed by
providing proper REE at universities.
However, no effort has been made to systematically compile, and analyse these
problems so that it is possible to have a bird’s-eye view of REE problems. This analysis
and presentation of the problems is referred to as “an integrated view of the REE
problems”. Some problems have been reported and investigated by researchers while
some remain only as reported problems. Therefore, this research aims to come up with
an integrated view of REE problems, followed by selecting one problem area to be the
research focus and addressing the selected problem by formulating a method.
In the first phase of the study, an integrated view of REE problems was produced. A
survey was then performed among students and lecturers who have studied and taught
RE course to verify the REE problems presented in the integrated view and to identify a
selected research focus. This leads to the identification of the research focus which is
teaching problem structuring and analysis.
The literature survey on problem structuring and analysis showed that it has not been
explicitly emphasised in the RE course but thought to be covered using requirements
analysis methods. For students with no industrial experience, it is difficult to learn
problem structuring and analysis using these methods. Therefore, in the second phase of
the research, a light-weight method was proposed to be taught to undergraduate
software engineering students in the RE course to enable them to understand and
perform the problem structuring and analysis. The method is referred to as L-Soft to
portray that it has transformed the idea of Soft system methodology into a light-weight
iii
(simple structure and easy to apply procedure) RE method. In order to facilitate the
understanding and application of the L-Soft method, students were provided with a
step-by-step guide on performing the problem structuring and analysis, a glossary of
terms used in the method and a sample of solved case studies. A web-based tool for LSoft
was developed to provide learning support to the students.
In the final phase of the study, the appropriateness of the method for performing the
problem structuring and analysis was validated using feature analysis performed by
lecturers and software engineers. The perceived adoption in practice was validated
using method acceptance testing performed by the lecturers and software engineers and
the results showed that the L-Soft method has a high likelihood of being adopted in
practice. Finally, an experimental study was performed among undergraduate software
engineering students to validate the method’s successfulness. The results showed that LSoft
was more efficient and effective than an existing analysis method and have a
higher likelihood of being adopted into practice rather than the existing analysis
method. |
