ABSTRACT
This paper outlines the evolution of Service Design from its origin within Interaction Design to its current
state of development, which is strongly affected by the growing complexity and collaborative nature of
service projects and social demands. The paper aims to provide a platform to ground the current state
of the discipline, to offer a critique of what has been achieved to date, and to outline the main research
questions that could drive Service Design Research in the near future.
Keywords: Service Design, Service Design research
1 INTRODUCTION
While Service Design is now recognised in much of the design community and service-design related
initiatives, events and research projects are growing in number, any attempt to precisely dene what
Service Design is and what it does are more difcult tasks. Design practice is quickly evolving -
stretching the borders and questioning the underlying bases of this emerging specialisation. This paper
stresses the importance of, and provides a rst platform to start a reection on, Service Design. We need
to understand where Service Design comes from, where we have been in the last two decades and where
we are now to better drive future research directions and make them meaningful to the current challenges
design is dealing with.
Without any intent to be exhaustive, this paper outlines the evolution of Service Design from its original
connection with the Interaction Design discipline and practice to its current state, which is strongly
inuenced by the growing of complexity and collaborative nature of service projects and society
demands. The analogy between designing ‘interactions’ (user - device interface) and designing ‘service
interactions’ or ‘service encounters’ (user – service interface) is at the core of Service Design’s identity
and practice. What has been gradually changing in the last decade is the context and nature of the
interactions that Service Design has been dealing with: from one-to-one to many-to-many interactions;
from sequential to open-ended interactions (Winhall, 2004); from within to amongst organisations.
Buchanan (1994) talks about ‘third order’ and ‘fourth order’ design to represent this recent need to move
where strategic decisions are made in order to be in a position to inuence future directions.
While ‘scaling up’, Service Design is also ‘reaching out’ and ‘deepening in’; this means that when both
the complexity of challenges and the objects of design become larger, design needs to collaborate with a
wider number of stakeholders and professions, but also to work ‘within’ service organisations and users
communities to provide tools and modes to deal with change and complexity on a daily basis.
The following sections will briey track this evolution, providing a platform to critique what has been
achieved to date, and what are the main research questions that could drive Service Design Research in
the near future.
2 DESIGNING SERVICE INTERACTIONS
As Richard Buchanan has asserted “design problems are ‘indeterminate’ and ‘wicked’ because design has
no special subject matter of its own apart from what a designer conceives it to be” (Buchanan, 1992: 16).
This means that the object and the practice of design depend more on what designers perceive design is,
than from a stable denition elaborated by a scientic community.
Building on this lack of ‘determination’ Service Design emerged as a contribution to a changing context

and to what a certain group of informed thinkers (notably Morello, 1991; Hollins, 1991; Manzini, 1993;
Erlhoff et al., 1997; Pacenti, 1998) started to perceive and describe as a new design agenda. In the ‘90s
the growing economic role of the service sector in most of the developed economies was in a clear
contrast to the practice and culture of design, which still focused on to the physical and tangible output of
the traditional industrial sectors.
During this rst decade Service Design research has been mainly dedicated to articulating and
legitimating why design could and should work on services. Only with the introduction of the Interaction
Paradigm, Service Design has started to build its own identity and legitimacy to work in this area. The
Interaction Paradigm in Service Design refers to the set of concepts, values and tools that derive from the
interpretation of services and of Service Design, starting from the area and the moments of interaction
between the user and the supply system (Sangiorgi, 2004). This area and the moments of interaction have
been referred to in different ways, such as: service interface, service encounters, touch-points, moments of
truth, etc.
The perspective that looks at services from the interaction point of view, is different from the one that
was trying to dene services as ‘products’ (Mager, 2004; Hollins, 1991) and therefore as objects of a
design process. Hollins and Mager, suggesting that services should be designed with the same attention to
‘products’ (see concept of ‘total design’), place the focus on the process (design management), with less
emphasis on the specicity of services and therefore of design contribution.
By contrast, the introduction of the interaction perspective has enabled a deeper understanding of
the nature of services and of Service Design, opening up a liaison with the schools, research and
methodology of Interaction Design. This perspective was proposed for the rst time in the PhD research
by Elena Pacenti (1998) who dened Service Design as the design of the area, ambit, and scene where
the interactions between the service and the user take place. She made an analogy between the design
of advanced interactive devices and the design of services, suggesting a shift from the interpretation of
services as complex organisations to one of services as complex interfaces to the user. This contribution
helped to position Service Design (focused on the service interface) between Service Management
(focused on service organisation) and Service Marketing (focused on service offering and market).
The Service Interface is the tangible and visible part of a service that a user can experience, beyond the
so-called ‘line of visibility’. It is made up of people, products, information and environments that will
support the user experience. Adopting a theatre metaphor, Service Designers are described as ‘directors’
that “manage the integrated and coherent project of all [these] elements that determine the quality of
interaction” (Pacenti, 1998: 123). Livework (London-based service design studio) describes Service
Design as the “design for experiences that reach people through many different touch-points, and that
happen over time”. Service Design therefore iteratively moves from designing intangible experiences to
designing the tangible elements that enable the desired experiences to occur in a coherent way.
This correlation and analogy between Interaction Design and Service Design has been further developed
both on a methodological and practical way. As Holmlid (2007) points out “the service perspectives
become a challenge to interaction design, and technology usage becomes a challenge to service design”.
A set of design tools have been then adopted and adapted mainly from interaction design disciplines
and practices, including such things as drama, scenarios, service interface analysis (Mager, 2004),
storyboards, ow charts, storytelling (Shelley, 2006), use case (Morelli and Tollestrup, 2007), scripts,
personas, role play, experience prototypes, etc. These tools and methods support the design practice and
at the same time contribute to the visualisation and testing of the service experience and interface - from a
general description to detailed implementation specications.
It should also be recognised that, so far, little attention and research has been dedicated to evaluating
what determines the quality of service interaction and how design contributes to this quality as well as to

its innovation. As Hoepy and Parker have said in “Journey to the interface” (2006) “being able to assess
the quality of the experiences is as important as knowing the efciency of the operations”. In addition
the so-called “service relationship” or “delivery” innovation (Green et al., 2001), which is where design
mostly intervenes, is one of the most diffuse kind of innovation in the service sector. However, because
of the interactivity dimension of services, which means that services are co-produced with users and are
often highly bespoke or customised, innovations are often made ‘on the y’ and are, therefore, difcult
to reproduce and measure. For this reason, new modes to evaluate innovation, mixing quantitative with
qualitative measures, are under investigation (http://www.innovationindex.org.uk). Service Design
scientic and professional community should participate to this ongoing discussion: a new interpretative
framework is required to depict and explore a new theory of service innovation that merges contemporary
innovation theory (that is more focused on the process/product dichotomy) with the contributions and
models of the user-design driven approach (Maffei et al., 2005).
3 SCALING UP AND REACHING OUT
The rst evolutions of the interaction paradigm have focussed mainly on the acknowledgment that the
design of service interactions cannot be separated from the overall service system and organisation; nor
can it be separated from the user context. Service interactions do not occur in a vacuum, they are highly
inuenced by the specicity of the situation. In the same way Interaction Design has developed studies
and theories to contextualise and locate interactions within wider systems and practices (Bødker, 2008),
Service Design has explored the contextual and systemic dimension of services in different ways and
adopted different theories in order to build conceptual models and theoretical frameworks that support
designers. These models and frameworks enable the designer to observe, understand and visualise
complex social systems of service organisations.
One research project has explored the application of Activity Theory to the analysis and design of services
(Sangiorgi, 2004; Sangiorgi and Clark, 2004). In a similar way to Interaction Design (Kaptelinin and
Nardi, 2006), Activity Theory has provided a framework to go beyond one-to-one (user-service interface)
and sequential interaction models (service scripts) to include wider systems of action and interactions.
In this framework, service encounters are described as mediated by the situated instrumental (service
evidences) and social (people, rules and roles) conditions (the service interface), but are also located in
the wider Activity Systems to which each service participant belongs. The benet of this approach is that
the encounters and potential conicts among service participants can be better understood when their
behaviour is situated within their wider context of action; the success of designing good services can be
increased by synchronizing the perspectives, goals and existing practices of service participants.
The same concern about synchronising multiple perspectives in Service Design, appears when describing
services as the result of a co-production among different stakeholders. Ramirez and Mannervick (2008)
talk about the shift from the design of ‘moments of truth’ to the design of ‘Value Systems’, from
‘Interaction Design’ to ‘Navigation and Enclave Design’. The main idea is to co-produce value for and
with users and a wider system of actors, the so-called ‘network of scope’. This approach is similar to
the one proposed by the Product Service System (PSS) literature, when talking about Solution Oriented
Partnerships (Jegou et al., 2004). PSS are described as the result of a “social construction, based on
‘attraction forces’ (such as goals, expected results and problem-solving criteria) that catalyse the
participation of several partners” (Morelli, 2006: 2). In particular when “dealing with complex challenges
of sustainable development, the designer can become a connector between multiple stakeholders, teasing
out issues and nding common values” (Brass and Bowden, 2008).
The need for design to work on a systemic level has increased the number of tools generated with the
scope of mapping out the potential system of actors, facilitating a conversation and co-designing and
visualising possible and desirable scenarios. Tools such as the ‘Activity System map’ (Sangiorgi, 2004),
the ‘service ecology’, the ‘map of interaction’ (Morelli, 2006), the ‘system organisation map’ or the
‘motivation matrix’ (Jegou et al., 2006) are part of these research studies.

4 DEEPENING IN
Service Design is also ‘deepening in’, meaning that, while scaling up the object of intervention, Service
Design is also starting to work more closely with and within organisations and user communities. This
seems to reect a general shift in the perception of ‘creativity’ itself as no longer the province of a few
specialisations, but as a capacity that permeates every part of modern life and draws upon the knowledge
and skills present in every organisation (Cox, 2005). Working with and within service organisations and
user communities generally aims at making people aware and able to use their existing creativity to deal
with change and complexity and co-develop innovative solutions.
The European research project EMUDE has investigated this kind of creativity, identifying examples
of ‘social innovation’ and exploring ways design could support and empower this emerging approach
to sustainable solutions. Manzini talks about the need to develop ‘enabling solutions, i.e. systems
that provide cognitive, technical and organisational instruments so as to enable individuals and/or
communities to achieve a result, using their skills and abilities to the best advantage and, at the same
time, to regenerate the quality of living contexts, in which they happen to live’ (Manzini, 2007: 6).
A similar consideration was developed by the RED team at the Design Council (now Participle) as a
reection on pilot projects such as Activmob (Vanstone and Winhall, 2006); the co-developed service
was actually a platform, with a set of rules and tools to ‘enable’ people to create their own way to keep
themselves active and healthy. In a key paper RED talks about ‘Transformation Design’ (Burns et al.,
2004) as a new discipline aiming at generating lasting changes in terms of their ability to change and spur
innovation in communities and organisations for socially progressive ends. Dott07 initiative has been the
consequent development of these researches, which worked with and within communities in the North
East of England to explore new and more sustainable ways of carrying out familiar, daily-life activities.
As for the other projects, the focus was on participatory approaches to design, using existing capacities,
resources and relationships as inspiration and sources for design.
The call for ‘creativity’ is also particularly strong within the businesses and public sectors. The latest
innovation studies on services highlight the need to create a permanent innovation culture within
organisations. Instead of focusing on single innovation projects, leaders are called to focus on building
innovation programmes (Tekes, 2008). On a professional level, this call has already had signicant
answers by service design studios such as Enginegroup with the design of a ‘social innovation lab’
for Kent County Council or as Thinkpublic that co-developed with staff from Birmingham North and
East NHS Primary Care Trust a prototype for a ‘Clinic to Go’, a portable carry kit containing all the
information required to set up a community clinic.
When the object of design becomes the way organisations conceive and redesign their own services,
Service Design needs to become more familiar with the dynamics and issues of organisational change.
Junginger (2007) suggests that if designers know about the different ways organisations change they
will be able to reect on their own design efforts: “the ability to assess their own work in the context of
organizational change allows designers to take on ever more important roles within the organization”.
Considering a ‘transformational change’ as the one that deeply affects an organization’s values and beliefs
(Rousseau, 1995 cited in Junginger 2007), the main question is how and when Service Design does have a
‘transformative’ effect on service organisations and how this can be evaluated.
5 CONCLUSIONS
This paper has briey described some of the main areas where Service Design is currently working on
and that represent the main ambit of Service Design driven innovation (Sangiorgi and Pacenti, 2008).
Although the number of initiatives and practitioners are starting to grow in this eld, there remains a lack
of theory. Furthermore, the development of the discipline seems to be mainly driven by and through a
reection on what practitioners do. This results in a strong emphasis on methodologies, with less focus
on the development of foundational theoretical frameworks. As a result Service Design currently lacks
a strong sense of research direction, which is reected by the limited number of (academic) publications

in this area. Here, the author has provided an overview of the main areas in which Service Design is
operating - which could be used as a basis for reecting on where to develop research directions in
Service Design.
The three areas of practice and investigation outlined above can be summarised as Interactions,
Complexity and Transformation. In turn, these could correspond to three main research areas that warrant
more detailed investigations:
1) Interactions: what is ‘quality’ in service interactions and how it can be designed and/or evaluated,
2) Complexity: what are the qualities and dynamics of ‘systems’ and what is the scale and mode of
intervention of Service Design
3) Transformation: how and when Service Design has a ‘transformative’ impact on service organisations
and user communities.
Service Design research is in its infancy. At this point in its development it has the opportunity and
responsibility to 1) investigate the above areas 2) relate them to existing knowledge and experience
developed in other similar Design Research areas such as Interaction Design, Participatory Design,
Experience Design and System Design 3) explore these emerging areas in collaboration with other
disciplines and theoretical frameworks that could support and enrich the practice and theory of Service
Design, such as Behavioural Science, Organisational Theory, Innovation Studies, Science and Technology
Studies, etc..
