qualified it as significant. Finally on the supply and
finances department there were just three new
transactions proposed to be integrated in the current
steps of the product acquisition process. All-in-all,
the number of new items identified was quite small
compared to the vast amount of transactions that
kept stable during this whole year.
On question 21 we tried once again to receive
input by the members of the organization on how
DEMO was appropriate for the modeling, by asking
them if they found the models of their departments
concise and unambiguous. Every collaborator that
answered to this question confirmed this quality.
Questions 28 and 29 aimed at reinforcing the
comprehensiveness quality while confirming if all
collaborators agreed with all the listed transactions
in the models deeming them as needed or even as
essential.
With questions 30 and 31 we intended to find
any eventual discrepancy between the collaborators'
perception of reality compared to the modeled
transactions. No interviewed person had a different
perception of what was modeled, further reinforcing
the comprehensiveness quality.
Question 32 intended to capture the validity of
the work produced nearly one year before, and how
it was still applicable to the current reality. Even
though some collaborators and documents used
changed, all eleven interviewees agreed that all
models still correctly described the reality of the
organization.
Question 35 aimed to get a perception on the
relevance given to the DEMO models by the
collaborators. The answers here varied, and although
most collaborators said yes, three couldn’t find any
reason for the models to be relevant and another one
stated that their activities were already so mechanic
that the models were of little use.
Question 37 had the intention to obtain the
predisposition to use these models to explain
someone who was not familiarized with the
organization and their new tasks. Answers were
somehow similar to the previous question. Most
collaborators said yes, but one questioned the ability
of someone new to understand these models,
although another also mentioned that the actor
transaction diagram, would be a good model to
explain the procedures without complications. Still
another person that also said “no” mentioned also
that the models could be complicated, and it would
be more profitable time wise to show them the real
operations in practice.
With questions 38 and 39 we intended once more
to validate one of the claimed qualities of DEMO
models, and their perception by the organization's
members. To do so, we asked if the models gave a
comprehensive and summarized view of the
organization's operation. All interviewees answered
yes, and when asked why they thought like that,
there was little variation in their answers. Most
replies focused on how everything was
discriminated and properly summarized, others
stated that it was properly diagrammed and reflected
their department of the organization, one also
mentioned that it gave a generalized view of
everything, and finally it was also stated that it
clearly reflected step by step the processes of each
collaborator and their respective tasks.
The objective of question 40 was to validate the
level of abstraction used in DEMO and understand
to what extent this is assimilated by the collaborators
of an organization. Ten out of the eleven
interviewees answered that it was useful to use this
level of abstraction, while one said otherwise. When
asked why the responses showed the understanding
of the reasons as they were mostly based on the fact
that the organization is in constant change, new
employees join, old employees leave and the
documentation is also under constant updates,
therefore this level of abstraction allowed for the
models to remain correct after a long period of time,
and still reflect the reality of the organization, as
also demonstrated in the previous questions of the
interview. Although most answers were centered in
these aspects, one of the collaborators had a very
different opinion that may reflect some difficulty
understanding the method, as the reason used to
justify the “no” was that this level of abstraction
makes it difficult to give proper credit to a
collaborator when its due, because no person names
are used, but instead only the organizational
functions.
The last question of this interview focused on
determining if the collaborators found important the
fact that, in the models, there was a differentiation
between the initiator and executor roles as well as
the specification of each transaction's main steps of
request, promise, execute, state and accept. Nine of
the answers were positive, eight focused on how this
helped indeed to clarify the responsibilities, and how
important it is to know who is responsible for what
within each department. One answer had a different
justification: the organization needs to be well
explained so that information does not get lost, and
this way of modeling did exactly prevent that. There
were two collaborators on the “no” side, one stating
that there was no need for this differentiation in their
department because a single collaborator usually did
