        <p>In enterprise modeling focus has been on capturing the right level of information and how the models represent this information. This paper purposes a project, which aims to look at the stakeholder and their participation in the modeling process. The paper proposes a solution for how the stakeholders can be included in the process by drawing inspiration from knowledge of visual conceptual models, knowledge from industry modeling processes and digital interactive collaborative techniques. The result is a collaborative framework or methodology, which can make communication with models more exible and engage a wider audience in the creation and maintenance of conceptual models.</p>

      <title>Background</title>
      <p>
        One of the key tasks in Enterprise Architecture (EA) is to analyse the current
situation and existing challenges in the enterprise with the active participation of
domain experts and decision makers [12]. Two of the elicitation approaches used
in this phase are interviews and participatory modeling workshops [12]. After an
iteration of the aforementioned elicitation approaches, possibly in combination
with other approaches [12], modelers create conceptual models of the knowledge
captured [12]. The models are created using one or several di erent notations, e.g.
Business Process Model and Notation (BPMN) [
        <xref ref-type="bibr" rid="ref9">9</xref>
        ], Uni ed Modeling Language
(UML), ArchiMate[
        <xref ref-type="bibr" rid="ref8">8</xref>
        ] and/or other frameworks, e.g. Architecture of Integrated
Information Systems (ARIS), Department of Defense Architecture Framework
(DoDAF). One of the fundamental attributes of the methods and/or frameworks
is the ability to circulate the captured knowledge back to the domain experts
and decision makers, such that they can evaluate and use the created models.
      </p>
      <p>Enterprises operate in an ever-changing marketplace; this means that, if the
enterprises want to stay competitive, it is crucial that it rapidly responds to any
changes. Creating, changing and updating an di erent enterprise model can be a
challenging task, particularly as the number of stakeholders increases. The tasks
become even more complicated, if the stakeholders are in di erent departments
and/or subsidiaries. A third aspect, is that a change can be initiated by any of the

stakeholders, for which the model is relevant. This puts additional constraints
on the process, which is used to change and update a model.

      <title>State of the art</title>
      <p>
        Conceptual modeling of organizations is not a new concept. 2 of the pioneers of
this topic were Young and Kent in 1958 [
        <xref ref-type="bibr" rid="ref3">17,3</xref>
        ]. Through the years, the topic has
matured in complexity and application. In the 90s, the focus seemed to change
from the question of the 80s: \What are we modeling?" to the questions: \Why
are we modeling and how are we modeling?". Furthermore, the scope of the
conceptual models changed from relatively well de ned applications into vaguely
de ned conceptualized applications or organizations [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. With the widened scope,
there emerged di erent approaches for modeling the enterprise architecture for
example: ARIS1, DoDAF2 and Zachman3.
      </p>
      <p>
        Among the common assumptions for these frameworks, is the notion that
enterprise modeling, to a certain extent, is a collaborative process among modeling
experts and stakeholders (domain experts and decision makers) [
        <xref ref-type="bibr" rid="ref2 ref4">4,2</xref>
        ].
Furthermore, they promote the idea of a single, consistent record of the enterprise model,
which should allow for multiple viewpoints [
        <xref ref-type="bibr" rid="ref7">7</xref>
        ]. The EA3 cube [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ], which builds
on the Zachman framework, claims to be a holistic method to model the EA
in a current state and one or several potential future states. This single model
repository idea should improve the connection between the di erent conceptual
models and concequently contribute valuable understanding of the purpose and
usefulness of a model.
      </p>
      <p>
        Visual conceptual models can be created by using a wide range of di erent
modeling notations. Di erent modeling notations are usually used in di erent
contexts: UML in computer science and BPMN is usually used to model business
processes. In sociology, a boundary object is a piece of information, "which has
di erent meaning in di erent social worlds, but the structure is common enough
to more then one world to make them recognizable" [13]. Boundary objects can
be used to create understanding between di erent contexts [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Based on the
idea of boundary object, the question is how the current models and modeling
notations can be used to create boundary objects, which can facilitate contextual
information sharing across di erent knowledge domains. This should improve the
the coherency of the model repository and consequently the whole organization.
      </p>
      <p>
        Another aspect, which will in uence contextual information sharing is the
fact, that notations are di erent in their graphical construction and these
constructions have an in uence on how well, a model is understood by the
stakeholders [
        <xref ref-type="bibr" rid="ref11 ref5">11,14,5</xref>
        ]. Therefore, this aspect needs to be analyzed, if we are to create
conceptual models, which enhance cross-contextual communication.
      </p>
      <p>Information sharing is considered an important approach to increasing
organizational e ciency and performance [16]. With the advances in information

and communication technology, sharing information across organizations can
become even more e ective. We have seen, how the internet has become a powerful
information sharing tool in software development [15]. The question is, how can
the internet and particularly mobile applications, support the usage of visual
conceptual models in contexts, where these haven't been used before.</p>
      <p>To summarize, the application space of conceptual models has continually
increased since the 80-ties, in context, scope and size. A number of di erent
frameworks have been proposed in order to manage and make the enterprise
architecture models actionable. Given the increased application space of
conceptual models and possibilities introduced by mobile devices, I will propose a
research project, which aims to use conceptual models for cross-contextual
communication. The rest of this paper is structured as follows: Section 3 describes
the problem I intend to address, section 4 describes the methodology, section 5
describes the expected contributions and sections 6 and 7 describe the current
status and the plan for the future.

      <title>Proposed Solution</title>
      <p>Given the overview of enterprise modeling and visual conceptual models
presented in section 2 and the background description in section 1. I conclude that,
this area presents considerable exploration opportunities. Furthermore, I
envision that my solution will take the path of empirically founded research, which
will demonstrate and provide evidence for the stated claims.</p>
      <p>The goal of this research project is to e ectively and e ciently engage the
stakeholders and modelers in cross-organizational collaboration, such that the
organization can rapidly respond to any changes in the marketplace. I propose
that we position the visual conceptual model at the heart of the conversation,
such that the message is also the medium. I will elaborate with the following
question:
1. How can visual conceptual models be used to communicate changes in an
enterprise and how can all the relevant domain experts and decision makers
be included in the communication?</p>
      <p>From section 2, responding to rapid changes in the enterprise through
stakeholder participation and using conceptual models to communicate the required
changes, has not been researched before. To explore the di erent aspects, I have
chosen to break, the overall question, down into the following sets of questions:
1. What are the main phases of a modeling process in a enterprise context?
(a) Which stakeholders are involved in each phase?
(b) What is their motivation?
(c) Which tools are used in the each phase?
2. What do we know about comprehension of visual conceptual models?
3. What do we know about collaborative creation of visual conceptual models?</p>
      <p>First, we need to establish, what the di erent phases are in a modeling process
in a certain context, which stakeholders are involved, their motivation and which
tools they use. This is necessary, in order to establish an initial state or the
current state of a airs. Dialog with modelers, seems to indicate that there are 3
di erent phases: knowledge elicitation, model creation and circulation. I have not
been able to nd any empirical evidence for this statement, therefore it would
be interesting to see, if this holds true.</p>
      <p>Secondly, there are several di erent visual conceptual modeling languages,
e.g. UML, BPMN and Event-driven Process Chains (EPC). I have chosen to
base my focus on empirical studies regarding visual aspects of UML. The intent
is to identify the existing knowledge about visual aspects of UML models and
their correlation to human comprehension. This knowledge could be used as
a building block, when evaluating visual aspects and their in uence on visual
conceptual model construction.</p>
      <p>
        Enterprise modeling is a collaboration between modelers and stakeholders
(see section 2). The keyword is collaboration and this will add the third
dimension to this research project. In [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ], the author explores the topic of
subjectoriented business process modeling and how this can enable people to represent
their knowledge about their individual ways of performing parts of a cooperative
work process. This article provides and interesting insight into mental models
and their externalizations. In [15], the author examines the role of social media
artifacts in collaborative software development. The thesis de nes the role of
social media artifacts as the timely dissemination of scenarios and concerns to a
diverse audience ... triggered by questions from users or articulation work. The
question is, can we draw inspiration from social media artifacts, subject-oriented
modeling techniques and boundary objects to enhance cross-enterprise
communication with visual models, such that it improves stakeholder participation and
the quality and the relevance of the enterprise models?

      <title>Methodology</title>
      <p>In order to evaluate and validate the outcome of this project, I plan to use a
empirical approach. The idea is to conduct an ethnographic study in a enterprise
setting, such that I can establish a initial state or more formally a null hypothesis.
In this study, I plan to observe, how models are created and continually updated
in an enterprise. The strength of this approach is that it gives very precise insights
into a certain context and population. A weakness is that the insight gained,
might be in uenced by aspects, which are outside the scope of the research.
Nevertheless, the intent is to nd a model of the process, which is used to create
conceptual model.</p>
      <p>In order to establish a foundation regarding visual aspects of conceptual
models and their correlation to human comprehension, I plan to conduct a Structured
Literature Review (SLR) on the empirical studies of visual aspect of UML
models. This will provide the basis for me to explore, how visual aspects a ect
communication with models. The strength of conducting a SLR is that the literature
is searched in a structured manner, which done properly could be repeated.</p>
      <p>
        It is clear that in any collaboration, there are human factors, which a ect the
collaboration paradigm [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ]. It is therefore, important to consider and evaluate
factors, which can in uence the communication with models. In particular, it is
important to identify any social factors, which could in uence the participation
in collaboration. To identify and human factors, the plan is to conduct a
qualitative interview study, with stakeholders involved in the ethnographic study.
      </p>
      <p>
        Technical solutions, which could be used to enable cross-enterprise
collaboration; such as social networks [15], blogs[15], wikis [15] or digitally augmented
table-tops [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ] is another area, which inspiration can be drawn from. The plan is
to develop a mobile application (phone or tablet) in order to evaluate di erent
collaboration approach. These approaches will draw inspiration from the before
mentioned social artifacts. The mobile application is expected to be a part of
the product portfolio of QualiWare ApS.

      <title>Expected Contributions</title>
      <p>The expected contributions of this research project are the following:
1. A Structured Literature Review on empirical research of visual aspects of</p>
      <p>UML models.
2. A case study, which studies the process of conceptual modeling in a given
context.
3. A study that focuses on the visual aspects, which a ect</p>
      <p>comprehension/understanding of conceptual models.
4. A study that focuses on which stakeholder aspects, which can in uence
participation in conceptual model creation.
5. A framework for creation and maintenance of conceptual models in a
distributed environment.
6. A mobile application, which implements the framework in 5.
The contributions above have relevance in di erent elds. The SLR has relevance
in the UML and empirical research communities in computer science. A study
on how conceptual models are created in industry, could provide an interesting
insight in a wide range of di erent conceptual modeling communities; e.g BPMN
and EA. An study into, which aspects can in uence stakeholders participation
in a modeling process can provide profound insight, for the development of a
collaborative framework and also a base for the evaluation of the same framework.
The framework aims to answer the overarching question of this thesis and as
such its focus is on the aspects, which motivate and engage stakeholder
participation in the collaborative creation of visual conceptual models and providing
the functionality for updating and continually evaluating the created models.
The mobile application is the concrete instantiation of the framework and is
intended to empirically evaluate it.</p>
      <p>The insight gained form this research project could potentially contribute to
a wide range of di erent modeling communities, because the question of this
thesis can be applied to software development, information systems and obviously
enterprise modeling.

      <title>Current status</title>
      <p>The emphasis of this project has, up until this point, been 2 di erent activities.
The rst activity is an SLR. The SLR aims to identify, which visual aspects of
UML models have been evaluated empirically, in addition to the identi cation,
the SLR aims to collect and map the results from the di erent studies. This
should result in a condense overview of the empirical studies, which have been
conducted and also identify areas, that could be explored further. The SLR
will also provide valuable insight into, which visual aspects could in uence the
understanding and communication with visual models.</p>
      <p>The second activity has been the development of a mobile application with
the primary functionality of showing stakeholders the conceptual models, which
address their concerns. The application also provides functionality, such that
the stakeholder can provide feedback and/or request a change to be made to a
given visual model. The rst version of the application was demonstrated in a
industrial conference hosted by QualiWare on the 05 - 06.05.2015.

      <p>The table 7 shows the current time-line for this project. The time line is split up
in to half-year periods where the major focus points of that period are described.
The focus of the time-line are the research activities, which are planned in that
half-year. Industrial and academic commitments such as courses and other
activities are not considered. At this early stage of the project the time-line is
subject to possible changes.
