For the Norm Analysis, the process involved to
verify, for each diagram element, whether it would
have norms associated. The process was finished
with a revision on the Proposal document.
The last two sessions of the Analysis phase were
dedicated to the elaboration of the user interface
prototypes and data structure. We observed that the
transposition was done directly from OD elements to
the corresponding screen elements, as mentioned in
previous work (Simoni and Baranaukas, 2003b). We
verified that OD contributed to the interface
organization into menus, screens and information to
be entered and visualized. Prototyping contributed
also to the validation of Semantic and Norm
Analysis, as the prototypes reflect the
materialization of the model and refinements on it.
3.2 Highlight of Results
As a practical work in a real company, we could
effectively test the potentiality of the proposed
approach. The choice for an IT internal project with
medium complexity allowed us to work with low
pressure of schedule, facilitating the revisions and
experimentation that were necessary. During the
process, we could observe the expectations and
results reached with new approach, illustrated below
in their comments.
“... It is based on the way communication is
carried through, clarity of meanings, etc.
(Semiotics). Normally we have difficulty to
communicate with non technical people and use
technical terms”.
With the discussion occurred by the end of the
Planning phase, we understood that they accepted
the approach and that it added value to their
development process, mainly in the activities of
requirements eliciting, one of our research focus.
“We are leaving a situation in which we make
the thing and think about it later. When the process
finishes we realize that it could have been done in a
different way”. “If we think earlier we don’t make
many mistakes”.
By the end of the Analysis phase, we observed
that the methods had been well assimilated and had
brought an improvement in their process of
understanding the problem and its context. In a
different way that they use to work, the new
approach led the group to discussions beyond the
technical questions:
“After the training I didn’t feel confident. The
confidence came with the practical works... The
documentation is complete, with a sequence that
allows to have a problem definition and
documentation of its context”.
By establishing the Solution Proposal as a
document that links the Planning and the Analysis
we covered the gap that we had observed in other
case studies (Simoni e Baranaukas, 2003b).
The outcomes of this case study allows us to say
that it was viable to introduce the concepts and
methods of the Organisational Semiotics into a
system development cycle that, according to
comments and observations, generated an adequate
documentation in volume and content, treated the
department of information system as a whole,
including the technical system.
4 CONCLUSION
Studies in user requirement eliciting need to address
how people understand the world and how to
represent this understanding.
The results of the case studies suggest that the
involved people had good understanding of the
approach, which allowed them to practice the
methods proposed by Organisational Semiotics and
MEASUR (PAM, SAM and NAM), mapping
elements of the analysis to interface prototypes and
data base.
Finally, the work that was initiated in the
company continues, to verify the influence of the
approach in the quality of the software application,
and brings us the perspective of new projects in
partnership.
