PSS MAIN CHARACTERISTICS
ROOTED IN A SATISFACTION-BASED ECONOMIC MODEL
each offer is developed/designed and delivered in relation to a
particular customer “satisfaction” (unit of satisfaction)
STAKEHOLDER INTERACTIONS-BASED INNOVATION
radical innovations, not so much as technological ones, as
new interactions/partnerships between the stakeholders of a
particular satisfaction production chain (life cycle/s)
INTRINSIC ECO-EFFICIENCY POTENTIAL
innovation in which is the company/companies’ economic and
competitive interest that may leads to an environmental
impact reduction (system eco-efficiency: decoupling the
creation of value from resources consumption)

Carlo Vezzoli
SYSTEM DESIGN FOR ECO-EFFICENCY:
A DEFINITION
“the design of the system of products
and services that are together able to
fulfil a particular customer demand
(deliver a “unit of satisfaction”), based
on the design of innovative interactions
of the stakeholders (directly and
indirectly linked to that “satisfaction”
system) where the economic and
competitive interest of the providers
continuously seeks environmentally
beneficial new solutions.”
[Vezzoli et al., 2014]

Carlo Vezzoli
A. “SATISFACTION-SYSTEM” APPROACH
design the satisfaction of a particular demand
(satisfaction unit) and all its related products and
services
SYSTEM DESIGN FOR ECO-EFFICIENCY:
NEW APPROACHES AND SKILLS

Carlo Vezzoli
THERE IS NOT ONE SINGLE PRODUCT TO BE
DESIGNED (ASSESSED), BUT RATHER ALL THE
PRODUCTS AND SERVICES (AND ALL THE
RELATED PROCESSES) ASSOCIATED WITH THE
FULFILMENT OF A PARTICULAR (CUSTOMER)
DEMAND OF SATISFACTION
... A “SATISFACTION UNIT” COULD BE DEFINED

Carlo Vezzoli
SATISFACTION UNIT:
(a car):
functional unit: trasportation of 1 persosn per 1 km
(possible with a car)
satisfaction unit 1: 1 person having access to his/her working
space (per 1 year)
satisfaction unit 2: 1 person having access to public services
delivering personal documents (per 1 year)
. ...
(possible even with other mixes of products and services)
a satisfaction unit require an approach at the same time:
. deeper (more products, services, stakeholders to be considered)
. more narrow (looking at one particular customer satisfaction)

Carlo Vezzoli
SATISFACTION APPROACH IN DESIGN
IS TO THINK MORE ON BEING (SATISFIED),
RATHER ON HAVING (PRODUCTS TO BE
SATISFIED)
[Ehrnelfeld, Sustainability by design, 2008]

B. “STAKEHOLDER CONFIGURATION” APPROACH
design the interactions of the stakeholders of a
particular satisfaction-system
NEW APPROACHES AND SKILLS

Carlo Vezzoli
[a parallel with product design: it imagines and defines
the technical performance and aesthetic characteristics of
“components” – materials/shape - and their
“connections” – joining elements - to respond to a set of
“requirements” ]
systems design for eco-efficiency: it imagines and defines
“connections” – interactions/partnerships –
between appropriate
“components” – socio-economic stakeholders –
of a system, responding to a particular
“requirement” - social demand for satisfaction -
design the interactions of the stakeholder of a

C. “SYSTEM ECO-EFFICIENCY” APPROACH
design such a stakeholder interactions (offer
model) that for economic and competitive
reasons continuously seek after environmentally
beneficial new solutions
NEW APPROACH AND SKILLS

Carlo Vezzoli
> CRITERIA AND GUIDELINES ARE NEEDED
> METHODS AND TOOLS ARE NEEDED to orientate
design towards system eco-efficent stakeholder
interactions
NOT ALL PSS ARE ECO-EFFICENT!
C. SYSTEM ECO-EFFICENCY APPROACH
design such a stakeholder interactions (offer
model) that for economic and competitive reasons
continuously seek after environmentally beneficial
new solutions

FOR DECISION MAKING (DESIGNING)
identify the (environmental) design PRIORITIES:
> CRITERIA relevance (relative) per system type
> most promising stakeholders’ INTERACTIONS
types (criteria related GUIDELINES)
INTERRELATIONS BETWEEN ENVIRONMENTAL
CRITERIA (AND RELATED GUIDELINES)
FOR A GIVEN SATISFACTION SYSTEM:
- some have HIGHER RELEVANCE than others
- can be SYNERGETIC or CONFLICTING
