        <p>Marketing sciences suggests that, with the maturation of the (digital) service economy, the notion of economic exchange, core to the economy, has shifted from following a goods-dominant logic to now following a servicedominant logic. Key to service dominance is the notion of value in use rather that value in exchange. Value is seen as being created in a process of co creation, involving resource integration. To design, and evaluate, different design options for value co-creation scenarios, a modelling framework is needed to capture such scenarios. The development of this framework is driven by different case studies.

      <p>Western countries have seen a transition from a goods-oriented economy to a
servicesoriented economy. Most, if not all, services delivered in the service economy are
actually digital services in the sense that they are obtained and / or arranged through a
digital transaction over information networks [16, 12]. As such, IT is also generally
seen as being the key enabler of the (digital) service economy [11].</p>
      <p>Marketing sciences [14, 4, 13] suggests that, with the maturation of the (digital)
service economy, the notion of economic exchange, core to the economy, has shifted
from following a goods-dominant logic to now following a service-dominant logic. Key
to service dominance is the notion of value in use rather that value in exchange. Value
is seen as being created in a process of co creation, involving resource integration, also
further blurring the distinction between consumers and producers.</p>
      <p>
        Combined with the digital transformation, the shift towards service dominance,
results in the creation of what might be called digital service ecosystems [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. In the (joint)
development / growth of such digital service ecosystems, infrastructural investments
(in people, infrastructures, processes, etc) need to be made by the participants in order
to prepare themselves for the actual co-creation of value. Such infrastructural
investments could e.g. include cultural / knowledge assets, as well as “institutions” in terms
of rules, norms, meanings, symbols, practices, and similar aides to collaboration [13],
social / contractual assets in terms of defined institutional arrangements [13], contracts
with partners in the value web, etc, as well as technological assets such as shared
technology platforms, etc.
      </p>
      <p>To ensure that such investments remain controllable, to manage coherence [15],
to ascertain if key quality concerns (e.g. sustainability, security, privacy, flexibility) are
met, etc., one generally suggests to use an design / architecture oriented approach [6, 9].
Such approaches typically involve modelling frameworks covering different aspects /
perspectives of the enterprise / digital service ecosystems, while also maintaining
coherence between these aspects / perspectives. Examples include ARIS [10] and
ArchiMate [5].</p>
      <p>As argued in [8], for value co-creation, it is important to take a holistic perspective of
the digital service ecosystems and its context. Concerns, such as sustainability, equity
between partners, etc, can only be considered sensibly at the level of the ecosystem
as a whole. During last year’s VMBO, we reported on work done, in the context of
the ValCoLa project, towards the development of a modelling framework language for
value co-creation [8], in particular the strategy we aim to follow in the development
of such a framework. One of the key messages was the need to use case studies in
the development of such a modelling framework. Contrary to e.g. the development of
ArchiMate [5], there is not (yet) a rich experience in the design of value co-creation
driven digital service ecosystems.</p>
      <p>In line with this, the remainder of this paper is concerned with early results
concerning one such case study in value co-creation, in terms of the ParkinsonNet4 concept
for improved healthcare for Parkinson patients (and their family) as pioneered in the
Netherlands.

        Background
Parkinson’s disease is a common and disabling neurodegenerative disorder [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. To
improve the quality of care, while at the same time reduced costs, for healthcare for
patients (and their families) suffering with Parkinsons disease, Dutch researchers in
the Parkinson’s domain have pioneered the concept of Parkinson networks. The Dutch
ParkinsonNet has indeed been able to achieve these goals [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ], triggering other countries
to try and copy the same model, such as Luxembourg.5
      </p>
      <p>
        The concept of a ParkinsonNetwork has introduced a new way of care, where
“specialised professionals and engaged patients work together to try to achieve optimal
outcomes” [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Key in this is that it introduces a “new “collaborative culture of care”
where specialised professionals and engaged patients work together to try to achieve

initiators of ParkonsonNetworks have a need to use such insights and / or capitalise on
their own experiences.</p>
      <p>
        Condering the broadness of the stakeholders involved in the “running” and
“growing”, of a ParkinsonNet, it is key to take a value co-creation perspective, thus ensuring
that the goals of all relevant stakeholders are met sustainably. This resulted in the
strategy to:
1. At a generic level identify:
– generic stakeholder types for ParkinsonNetworks,
– generic potential value flows between the stakeholders,
– any generic “rules of the game”.
2. At the more specific level (of a specific network) identify / specialise:
– specific stakeholder types for ParkinsonNetworks,
– specific potential value flows between the stakeholders,
– specific “rules of the game”?
3. Articulate growth strategies:
– How to grow a sustainable ParkinsonNetwork?
– Are there different stages?
– Different roles of stakeholders during different stages?
– Is it possible to make changes to the rules of the game?
An example, of a “rule of the game”, and how this may differ between countries, is the
fact that in the Netherlands, health insurance companies provide a better coverage of
the costs, when patients use a health professional from the ParkinsonsNetwork. Based
on experiences within the network, there is evidence that the overall costs of
Parkinson disease related health care is lower when patients receive care via the network [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ].
This enables to insurance companies to let patients essential “share” in these financial
benefits, making it more attractive for patients to seek health care from the network. In
Luxembourg, however, such differentiation of refund of medical costs is not allowed
due to the “free choice” principle, which allows patients to freely choose which
(relevant) health care professional should treat them.
      </p>
      <p>From the perspective of the ValCoLa research project, answering the above
questions also provide(s/d) insights into the modelling concepts needed in a modelling
framework for value co-creation.</p>
      <p>
        For the identification of stakeholders, Figure 1, as provided in [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ], served as one
of the inputs. However, additional stakeholders are involved as well, for example,
insurance companies, government agencies, funding agencies, etc. Figure 2 provides an
overview of the resulting landscape of potential stakeholders. The role (or even
presence) of these stakeholders may differ from country to country.
      </p>
      <p>In identifying the typical stakeholders and their goals, we soon realised that there
where goals (and even stakeholders) that pertain to the running activities of the
network (e.g. patients needing care, health care professionals looking job satisfaction by
being more effective in providing healthcare, etc) and those that pertain to growing the
network (e.g. insurance companies, governments, health care organisations, etc).</p>
      <p>The overview of the relevant stakeholders, at a generic level, is shown in Figure 3.
For each of the arrows shown in Figure 3, a further analysis was made (at the generic</p>
      <p>Parkinson network
level) regarding the potential value flows between the involved actors. An overview of
this analysis is provided in Figure 4.</p>
      <p>
        The inclusion of re-usable, value co-creation driven, strategies to grow
ParkinsonNetworks results in a need to have a framework to “codify” such strategies. To this
end, we will use the underlying structures as used in the ISPL (Information Services
Procurement Library) [
        <xref ref-type="bibr" rid="ref2">2, 7</xref>
        ] as a starting point. In particular, in terms of its situational
analysis, risk analysis (in terms of the latter), and heuristics to select / define risk
mitigation strategies and project delivery strategies.

      <p>Conclusion and next steps
In this paper, we discussed the early results of an ongoing value co-creation case study,vin
terms of the ParkinsonNet concept for improved healthcare for Parkinson patients (and
their family) as pioneered in the Netherlands.</p>
      <p>
        We are now in the process of (1) better documenting the potential stakeholders
and their potential value exchanges (based on a literature study on papers dealing with
the development of Parkinson networks), (2) more broadly validating these with the
domain experts, (3) making the “reasoning structure” used in ISPL [
        <xref ref-type="bibr" rid="ref2">2, 7</xref>
        ] suitable to
capture different growth strategies for ParkinsonNetworks, in particular by adding the
role of value co-creation between stakeholders, and (4) capturing (and comparing)
successful / failed strategies in growing ParkinsonNetworks explicit in terms of the former
“reasoning structure”
