Abstract. In this study, we examine the challenges that arise from an interdis-
ciplinary collaboration in the field of Software Engineering through a common
project between the undergraduate students of the Department of Computer En-
gineering and the Visual Communication and Design Department of Yeditepe
University in Istanbul, Turkey. This collaboration between the two departments
was carried out for two consecutive years. Each year a certain number of groups
were formed including students from both departments. Every group had the
objective to create a game as this type of application requires both design and
computer programming skills. The results reveal that this collaboration is bene-
ficial for both students and instructors. From the students’ point of view, the
contact with people from different backgrounds prepares them for real-life situ-
ations. Additionally, this experience has also an education impact as it enables
instructors to understand the difficulties students are facing, which as a result
can be used as indicatory feedback to constantly improve the quality of the
course.
Keywords: Software engineering education, interdisciplinary approach, educa-
tion improvement.
1 Introduction
The aim of this study is to demonstrate the benefits of having an interdisciplinary
approach in the teaching of Software Engineering at undergraduate level. More pre-
cisely, in Istanbul, Turkey at the Yeditepe University, for two consecutive years, the
students of the department of Computer Engineering (CSE) collaborated with the
Visual Communication and Design department (VCD) for the creation of a game. In
each year ten teams were created with members of both departments having as an
objective to design and create a game that would be played on a smartphone. The
Visual Communication and Design department students were assigned to propose an
idea, design the characters, and create the scenario of the game. On the other hand, the
students from the Department of Computer Engineering were responsible for carrying
out these ideas, integrating the design and sketches to the game and propose correc-
tions when the specifications were not realistic or too difficult to be realized. This
study focused mainly on the challenges, difficulties and gains as experienced by the
students of the Computer Engineering Department. The idea and the motivation for
this collaboration is based on the challenges and difficulties that arise from cultural
differences between different disciplines and giving the possibility of better under-
standing and collaborating with people from different disciplines is the main reason
for this interdisciplinary project. Especially for the students of computer engineering,
understanding professionals from other domains nowadays, became very important,
because with the rise of new technologies, people from different professions have to
collaborate and interact with each other.
The collaboration was organized as follows: in the beginning, a kick-off meet-
ing was held with the participation of both students and instructors, having an aim to
introduce the students to each other in order to form the working groups. After the
groups were established, the communication between the students of both depart-
ments was facilitated via help of a web-based project management application,
smartphone messaging, phone calls and weekly or biweekly meetings. After seven
weeks, the teams had a presentation in front of the instructors in order to show their
progress in terms of UML diagrams, videos, and their overall design. Finally, at the
end of the semester, a presentation day was organized where the students presented
their work, demonstrated their game and submitted their project report. The students
of the Department of Computer Engineering filled out a questionnaire covering sub-
jects as the organization of the project, its usefulness for their professional life in
terms of new knowledge, and the communication between them and with the students
with the other department.
The results extracted from the questionnaires and also from the personal expe-
rience of the instructors during the two consecutive years of the interdisciplinary col-
laboration showed that this project was very fruitful in terms of applying software
engineering processes and participating in different phases of the project. On the other
hand, the major problems were encountered in terms of communication, especially
with the members of the Visual Communication and Design department. As the in-
structors have also verified that communications issues arose equally from both sides
we have concluded that along with the contribution of a real-life experience for the
organization and execution of a software engineering project, a major advantage of
this type of interdisciplinary project is that it provides an educational method that can
teach future professionals how to work and coexist with the “other” in the frame of a
common project.
The rest of the paper is organized as follows: Section 2 presents the related
works, Section 3 describes the methodology that was used during these two consecu-
tive terms, and Section 4 illustrates some results and discusses the findings. Finally,
Section 5 summarizes our conclusions and proposes some future works.
2 Related Work
Software engineering education represents a big challenge as a wide range of skills
and talents is required [1]. As a result, various teaching methods were proposed [2-4].
Because of the particular nature of this course, emphasis is given to different aspects
and compromises are done to balance the teaching time between theory, practice,
development or management. Moreover, in an environment where interaction be-
tween users and developers is must, non-technical skills essential for a software engi-
neer such as communication skills and the ability to work on a team are critical. Espe-
cially in the modern era, software applications necessitate the collaboration of more
than one disciplines.
In an effort to address the problems arising from the lack of communication
between users and developers, methods were proposed to reduce the gap between the
education and the ‘real world’ conditions. In [5] this issue is addressed through an
interdisciplinary approach and methods aiming to simulate the working environment
are introduced. In general, the importance of interdisciplinary approach is being rec-
ognized as a tool of skill development for engineering education [6]. The collabora-
tion of software engineer students with students from different departments provides a
way of interdisciplinary work as shown in [7] where the Computer Science, the Busi-
ness Management and the Product Design programs formed mixed groups for accom-
plishing common projects. In another study [8] the interdisciplinary work included
vaguely formulated projects and collaboration with artists, thus revealing the wide
and demanding area of software engineering. In [9], the advantages of implementing a
game design for teaching software engineering are demonstrated as it is an attractive
subject where all aspects of a software lifecycle can be represented. Finally, in [10], a
design of a mixed-majors undergraduate course is presented including computer sci-
ence and graphic design students. In this course the goal is to learn from each others’
expertises through the creation of mobile applications. This paper identified the chal-
lenges and opportunities that aroused from the cultural differences between the two
departments.
3 Methodology
As mentioned before, for the case of our study the realization of the interdisciplinary
approach in software engineering education is based on the collaboration between the
Department of Computer Engineering and the Visual Communication and Design
department. For this reason, we have concluded that an efficient and attractive way
could be the creation of a computer game that would run on smartphones.
Fig. 1. Organization of the interdisciplinary projects. The CSE and VCD departments are form-
ing 10 groups where the CSE members have distinctive roles. For each group, the objective is
to create a computer game for smartphones. Their work is evaluated at two milestones – namely
First Presentation and Final Presentation.
The advantages are multiple for students of both departments: from the point of view
of CSE students the creation of such a game makes them more experienced in mobile
programming, and game programming in general. From the point of view of VCD
students, it challenges their creativity in terms of graphic design and game scenario.
Moreover, it makes both students think together about the creation of an original
game. At the early stages, we have witnessed a certain enthusiasm from the part of all
students.
3.1 Groups
The collaboration is organized as follows: Initially, each department divides its stu-
dents into 10 groups. Then, a common meeting is organized with students from both
departments in a joyous and easy-going atmosphere, where the 10 teams of each de-
partment try to match with a counterpart from the other department. When the groups
are matched, they result in 10 common groups with 4-6 students from the CSE de-
partment and 2-3 students from the VCD. In CSE department around 60 students are
taking the course every year in their third year of their academic studies. Among
them, 35% are female. In two consecutive semesters there was only one foreign stu-
dent. Finally, the Software Engineer course has three credits into the curriculum of the
CSE academic program.
From the Software Engineering course's point of view, the goal of this collabo-
ration was not only the final product but the steps that the students would have to take
in order to achieve the final product, which is the computer game. To do so, the stu-
dents of the CSE department were asked to identify certain roles and missions for
every member - such as designer, developer, and tester. This organization also in-
cluded included the post of the project manager that would lead the team. A person
responsible for the communication with the partnering students from the VCD de-
partment. Furthermore, they had two or three programmers roles and a person respon-
sible for writing the reports, preparing the presentations and demos in collaboration
with the project managers. Figure 1 presents the organization of the groups from the
two departments.
3.2 Communication
In terms of communication, frequent meetings (every one or two weeks) were orga-
nized between the teams of both departments. The goal of these meetings was to en-
hance the relations between students from two different departments, and also to
evaluate their progress by communicating about the problems that they were facing.
Additionally, a web-based project management tool was used in order to allow them
to organize and check the progress of the project but also to give to the instructors the
possibility to check if all necessary steps were taken. Finally, e-mails, phone calls,
and messaging applications were also used. We have noticed that the messaging ap-
plications were the preferred medium of communication between students.
3.3 Software engineering process
All the teams have applied the incremental development method as their development
process. The reason for this lies in the fact that the teams were small and the time for
creating the product was short. More specifically, with this type of development high-
ly priority parts of the game were developed first, like principal game functionalities
and later other parts were delivered, like points system, ranking, etc.
3.4 Milestones and evaluation.
As presented in figure 1, there were two milestones in the lifecycle of the projects.
The first one was scheduled seven weeks after the beginning of the project, which
entailed an oral presentation for each group using slides, audio themes, and initial
demos. At this stage, the instructors asked the CSE students to express their design
with the help of UML diagrams, justify the selection of platform, and explain the
reasons for choosing their proposed programming languages. The VCD students were
asked to present their graphic design, the audio themes and the scenario of the game.
Every group was asked to make a presentation shorter than 10 minutes.
The second milestone was the final common presentation with the presentation
of the final product. This presentation was less technical and more focused on the live
demo of the game. Together with the presentation, a technical report should be sub-
mitted, which included all details concerning the design, the implementation, and the
tests that were carried out in order to verify and validate the product. Finally, the in-
structors evaluated and graded the project based on the presentations, the product, and
the reports. Lastly, the CSE students were asked to fill in a questionnaire to collect
additional information concerning the interdisciplinary experience, the benefits, and
concerns that arose from this project.
4 Results & Discussion
After two consecutive years and 20 different teams, which accumulates to a stagger-
ing number of 200 students, we have made the following observations: firstly, on
average the quality of the produced computer games was below the expected. Consid-
ering the number of people working on that project and the time given, it was ex-
pected that the games would be better in terms of graphic design, and complexity.
Despite this fact, every term, there were one or two games that had an outstanding
quality, which brings us to the conclusion that game programming as a task is not a
straightforward procedure. Secondly, the enthusiasm that was observed at the begin-
ning among the students of both departments decreased during the semester. The third
observation is related with the application of processes of software engineering. For
the last two consecutive years, the CSE students managed to apply with success the
procedures related to the specifications, the requirements, the organization of the pro-
ject and write relatively good reports. The instructors could verify the above by fol-
lowing the organization charts, the reports, and the meetings of the different teams.
This achievement is one of the contributions of this interdisciplinary project because
it was carried out in a real-life environment with realistic constraints where students
from other disciplines participated. This outcome is also reflected in the answers to
the relevant questions of the student questionnaire, which was given to them at the
end of the semester. Most of the students answered positively when they were asked
about the organization of the project, the procedures followed and the overall contri-
bution of this project to their knowledge. Table 1 presents some questions of the ques-
tionnaire related with their overall experience about this project. We can observe that
in general the students were positive when asked about the benefits that had during
this work.

ment issues
Finally, the fourth observation is related with the communication between
members of the CSE department and the communication and relations between the
members of the CSE and VCD department. After personal discussions between the
instructors and the students and according to the answers to the questionnaires, the
personal communication was the toughest challenge of this project.
From the point of view of CSE students, the most commonly identified prob-
lems were the lack of responses that occurred when communicating through a mes-
saging or email medium and the delay in the deliverables from the part of the VCD
department. At this point, it is worth to mention that after speaking with the instruc-
tors of VCD department, the instructors of CSE department observed similar prob-
lems but this time from the students of VCD towards the students of CSE department.
In a certain sense, it looks like the identity that is created to a student from his partici-
pation to a particular department influences his communication with the students of
other departments and expectations or behaviors that are considered to be normal are
not finding their correspondence when speaking to the “other”. The frustration that is
created from this communication is eventually the biggest gain of this interdiscipli-
nary project as it prepares them for the real-life environment. It may also explain the
low quality of the projects and the reduction in enthusiasm during the semester.
5 Conclusion
In this study, we have described and presented the results of an interdisciplinary pro-
ject between the students of the Department of Computer Engineering and the Visual
Communication and Design department of Yeditepe University in the course of Soft-
ware Engineering class. The results showed that this project was very beneficial in
terms of learning the procedures and processes of Software Engineering. On the other
hand, this project gave indications that the majority of the students were not ready to
face professionals from different disciplines where different behaviors, attitudes or
methods of work can be encountered and clashed. Preparing students for real-life
conditions were the main objective of this project and the problems that have arisen
during this endeavor showed that it has helped to contribute towards the right direc-
tion. Changing the number of students in the groups, considering different depart-
ments for collaboration and exploring new methods of communication and control are
among the future work of this study in an effort to prepare the students for their future
professional life and improve this experience for the students.
