The second edition of this workshop series (HuFaMo 2016) took place in Saint Malo, France, in October 4, 2016. HuFaMo 2016 was integrated in the ACM/IEEE 19th International Conference on Model Driven Engineering Languages and Systems, the premier conference on systems and software modeling. In this second edition, HuFaMo attracted a considerable number of participants, including researchers and practitioners. The workshop included the discussion of 5 papers and a working session on how to build up the HuFaMo community and leverage the synergies among participants.
The HuFaMo Program Committee selected 5 papers for presentation in the workshop. Here, we briefly outline some of the main contributions of each of those papers.
Rodi Jolak presented a new generation software design
environment, OctoUML. OctoUML supports the creation of
informal and formal notations and the transformation between
them. Moreover, it supports multiple modes of interaction (e.g.
mouse and keyboard, touch and voice). The tool was
evaluated by conducting a user study. The obtained results from
the user study show that OctoUML provides a user-friendly
environment and has the potential to effectively support the
activities of the designers [
Max Kramer presented a plan of experiment for empirically
assessing understandability gain of using a Model
Transformation Language (MTL) instead of a General Purpose
Programming Language (GPPL). During the experiment the
subjects have to answer a paper-based questionnaire in order
to demonstrate their ability in understanding the effect of
transformation code snippets. To evaluate the influence of
MTL on the quality and speed of program comprehension,
Max proposed two statistical tests. The tests actually compare
the average number of correct answers with the the average
time spent on answering them [
Eric Souza presented a design of an experiment to compare
two methods to specify economic values (e3value and
valuedriven development). In particular, the experiment design
provides means to predict the acceptance of one particular
method in practice. The criteria of acceptance are based on: (i)
the effort of applying the particular method, (ii) the quality of
the created artefacts, and (iii) the perceptions that are perceived
by the users regarding the quality of the method [
Daniel Str u¨ber presented a design of a controlled experiment
to investigate the benefits and drawbacks of two specific reuse
mechanisms for model transformation languages: rule
refinement and variability-based rules. The aforementioned
mechanisms represent two different reuse paradigms: modularizing
rules by composing them from smaller shared fragments,
versus maintaining a single integrated representation via
variability annotations. Daniel proposed to compare those mechanisms
by running comprehension and bug-finding tasks. The purpose
of running such tasks is to investigate understandability,
bugfixing and modification tasks to study changeability [
Finally, Yosser El Ahmar presented and run an empirical
activity at HuFaMo16. The purpose of the empirical activity
is to understand: (i) what are the effective implementations of
the size visual variation to all types of graphic components
of the UML sequence diagram, (ii) how the effectiveness
of each implementation can be controlled by the type of
information to highlight, and (iii) how the effectiveness of each
implementation can be controlled by the size of the diagram
containing the implementation and its layout [
The authors would like to thank the authors who submitted their works to this first edition of the HuFaMo workshop, all the attendees of the workshop sessions, the PC members who reviewed the submissions, and the remaining organization members.
