      <abstract>
        <p>Digital Innovation Hubs (DIHs) support businesses in their digital transformation, providing technological, educational, and financial services, as part of a rich ecosystem of stakeholders. Being quite new-born organisations, the offering of DIHs very often doesn't follow a common standard pattern. To support DIHs' daily activities both with customers but also in cross-regional initiatives and to define a sustainable offering matching the customer needs, a structured suite of approaches (called METODIH and grounded on the well-known and widely adopted D-BEST reference model) is proposed. The approach provides four basics tools: service portfolio analysis, customer journey analysis, digital transformation pipelines, and business and governance models. In particular, the paper introduces the addition to the D-BEST model of the Remote macro-class in the artificial intelligence domain. As a result, the DR-BEST model, based on six macro-classes, is presented as an improved version of the D-BEST, i.e., the previous standard framework for classifying DIH service portfolios.</p>

      <title>1. Introduction</title>
      <p>
        To boost the digital transformation of European enterprises [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ], Digital Innovation Hubs (DIHs)
are playing a key role, by helping companies to become more competi-tive with regard to their
business using digital technologies and by promoting cooper-ation among them [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ]. The objective is
to ensure that every company can take ad-vantage of digital opportunities, by providing them with a
different set of services also depending on the assets and competences characterizing each DIH
(access to technical solution and facilities, funding opportunities, support for training and skills
development) [
        <xref ref-type="bibr" rid="ref3">3</xref>
        ]. The DIHs offering is not addressed only to enterprises (identified as possible
technology users), but also to technology providers, students, and policy makers, by managing a
network of stakeholders, enhancing collaborative projects [
        <xref ref-type="bibr" rid="ref4">4</xref>
        ].
      </p>
      <p>
        To this regard MIDIH project [
        <xref ref-type="bibr" rid="ref5">5</xref>
        ] conducted a preliminary analysis about tools and methods
required to support DIHs in shaping their offering according to the ecosys-tem requirements. The set
of tools and techniques elaborated in MIDIH and grounded on the original
Ecosystem-TechnologyBusiness (ETB) model [
        <xref ref-type="bibr" rid="ref6">6</xref>
        ], was initially im-proved and validated in the DIH4CPS project, under the
name of the Data-driven Business-Ecosystem-Skill-Technology (D-BEST) reference model [
        <xref ref-type="bibr" rid="ref7 ref8 ref9">7–9</xref>
        ].
The DIH4CPS project developed the D-BEST Suite composed of the framework to con-figure DIHs
service portfolios, the method to analyse the DIHs’ customer journeys and the coupling of the
ECOGRAI method [
        <xref ref-type="bibr" rid="ref10">10</xref>
        ] with the D-BEST model to develop KPIs for cross-collaboration among
      </p>
      <p>DIHs. Finally, in the AI REGIO project, the D-BEST Suite proposed by DIH4CPS evolved in the
METHOdology for DIHs (METODIH) composed of four tools: service portfolio analysis, customer
journey analysis, digital transformation pipelines, and business and governance models. METODIH
was developed and tested by the network of 13 DIHs belonging to AI REGIO, who developed further
components to better answer to the needs of a specific domain (i.e., the artificial intelligence (AI)).
The most important novelty has been the addition to the five main macro-classes of services
composing the D-BEST model of the Remote dimension. The paper has the aim of introducing both
the METHODIH approach and the extended taxonomy of the DR-BEST reference model, which
repre-sents a key tool to run the service portfolio analysis. Indeed, this paper aims at provid-ing a
more detailed understanding of the Service Portfolio analysis, which represents the first step of the
methodology and has been adopted both by AI REGIO’s DIHs and Didactic Factories (DFs).</p>
      <p>The paper is structured as follows. Section 2 presents the METHODIH approach and its four
modules, and Section 3 shows the DR-BEST. Section 4 reveals the results of the DR-BEST model to
the AI REGIO network and Section 5 concludes the paper.</p>

      <title>2. METHODIH approach</title>
      <p>
        Paragraph METHODIH is a METHOdology for DIHs defined within AI REGIO project [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ],
aiming at supporting DIHs with a structured approach, providing four basic tools to define a
sustainable offering matching their customer base needs:
• the Service Portfolio Analysis, to configure DIHs service portfolio according to a common
framework, to facilitate DIHs collaboration and to stimulate the definition of new services to
get an extensive portfolio,
• the Customer Journey analysis is proposed to understand typical needs, ex-pectations and
interaction workflows by the various ecosystem stakeholders. Customizable templates for six
different customer types (Technology Pro-vider, Technology User, Student, Policy Maker,
Start-up, Experimenter) are provided, consisting in five-steps journeys that describe the main
stages of the digital transformation process. A fundamental step in this analysis is the
identification of blocking points where DIH should support the customer.
• the Digital Transformation Pipelines: to combine the demand (customer needs) with the
offering (service portfolio), and to define in a structured way the customer interaction with the
DIH and the steps to be pursued to imple-ment the evolutionary pathway and overcome
blocking points. The temporal component is a fundamental aspect in a definition of service
pipelines. If tai-lored on specific customers’ profiles, pipelines are transformed in success
stories to reinforce the catalogue of best practices to be followed.
• the Business and Governance Model: to guide the DIH in the definition of a model to describe
its business, that takes into account the complexity of a its customer base and a
multistakeholder network, including sustainability for cross-regional activities. One specific
dimension is the Governance, that takes into account the complexity of the collaborative DIH’s
activities.

      <title>3. The DR-BEST Reference Model</title>
      <p>
        The Service Portfolio analysis is performed by the DIH starting from a structured approach
proposed, called DR-BEST analysis. The framework has been conceived for the DIHs, to define their
as-is service portfolio and to identify in their offering the gaps to be filled. Services are classified
according to a 3-levels taxonomy and this has a twofold advantage: on one side it shows a full picture
of the possible services that a hub could provide and on the other, it guarantees that services are
presented in a standard and comprehensible way. The macro-classification (level 1 of the taxonomy)
groups services in six different classes (Data, Remote, Business, Ecosystem, Skills, Technology),
from where the name DR-BEST comes; for each class, level 2 and level 3 are defined to better detail
and classify the type of activity. In AI REGIO, the first version of taxonomy adopted was the
DBEST (without the “R”), as previously com-ing from MIDIH and DIH4CPS projects results [
        <xref ref-type="bibr" rid="ref7 ref8">7, 8</xref>
        ].
Then, to better describe the DFs offering (that typically have a more technological approach with
respect to DIHs) and in response to increasing need of remote support (mainly related to the Covid-19
restrictions), the D-BEST service taxonomy has been enriched, including also the “R” class of
services and becoming DR-BEST. The DR-BEST catalogue (Figure 1) con-tains in total 69 different
services as level 3, distributed over the six classes.

          While a complete overview of the five macro-classes typically composing the D-BEST model is
provided in [
          <xref ref-type="bibr" rid="ref7 ref8 ref9">7–9</xref>
          ], this paper wants to present the Remote dimen-sion, introduced mainly for the DFs
operating in the AI domain. This class contains all the services that a DIH/DF may provide from
remote to enable experimentation and that don’t require the physical interaction with the customer.
The sub-classes identified cover different degrees of DF-customer interaction, including four type of
assets that can be put at disposal: data space (Real Time Industrial Data Platform, Assets
Administration Shell, Assets Data Marketplace), ICT as a Service (Software as a Service, Platform as
a Service, Infrastructure as a Service), Digital Twin (FEM/CFD/FSI simulation, Discrete event
simulation, Ambient virtualization), Assets as a Service (Teleoperation, Monitoring platform, Avatar).

      <title>4. Results in AI REGIO project</title>
      <p>
        The AI REGIO Ecosystem is based on a Network of 13 DIHs and 10 DFs and the purpose is to
extend it within the end of the project. Both DIHs and DFs have been invited to compile their own
Service Portfolio, leveraging on the DR-BEST model, with a threefold objective: i) to reason about
their offering describing it according to a standard framework; ii) to identify strengths, weaknesses
and areas to be enhanced, just by evaluating the gaps of their Portfolio; iii) to foster collaboration with
other DIHs, comparing the Portfolios and sharing competences. Having at disposal the DIHs
Portfolios of services, described according to a common pattern, has allowed to populate the AI
REGIO portal [
        <xref ref-type="bibr" rid="ref11">11</xref>
        ], conceived as a collaborative platform to over-come the fragmentation of regional
actors and to make their offer more visible and coherent. Figures 2 and 3 are extracted from the AI
REGIO portal – Service Market-place, showing respectively the Service Portfolio of the DIHs
Network and DFs Net-work, according to the DR-BEST taxonomy.
      </p>
      <p>The DIH Network provides a total of 311 services, whose 30% is covered by Eco-system services;
Business and Ecosystem offering cover together the 63% of the Port-folio denoting the strong attitude
of DIHs in brokerage and financing activities and in Community management and organization of
dissemination and promotion events.</p>

      <p>On the other side, DFs present a different profile: even if Business and Ecosystem services still
represent a large portion of the Portfolio, they together cover only the 40% of the total number of
services, with a predominant percentage of educational and technical offering. Actually, by definition,
a DF has a didactic component (that is, Skill related) and it is a Factory (that is, equipped with a
facility where it is possible to test new technological solutions).</p>

      <title>5. Conclusions</title>
      <p>The paper provides an overview of the METHODIH framework with a specific fo-cus on the
Service Portfolio analysis, which is the first step for DIHs willing to follow the methodology. It
presents a concrete application inside the AI REGIO ecosystem, involving both Digital Innovation
Hubs and Didactic Factories, having the opportuni-ty of describing their current portfolio in a
structured way as well as starting reason-ing on Remote offering (that is getting more a more relevant
in last years).</p>
      <p>Finally, the DR-BEST analysis allows the DIHs/DFs to define their own profile in the perspective
of collaborative activities: in the context of the paper the analysis has been shown only at Network
level to provide a general picture of the two communi-ties; however, at single DIH level, the Service
Portfolio analysis is very useful to put in light which are the strongest areas of competence and those
to be better improved, outlining the DIH profile.</p>
