3. Objectives
•
•
•
•
•
To recognize the importance of Services Science
Management and Engineering (SSME);
To explain what a service oriented, large and complex
system means;
To present the Galileo present status and the
preparation to its Early Services phase;
To describe the pragmatic approach taken and the
engineering activities needed for the provision of
Galileo services;
To suggest that beyond the obvious technological and
technical challenges, a service provision perspective
requires a conceptual paradigm shift much more
difficult to accept than that required by systems
engineering.
4. What is a Service System?
•
•
Service (or service-oriented) systems are systems
meant to provide value-added services through the use
of technology (mainly communications and computer
technologies);
A “service system” has been defined as a dynamic
configuration of people, technology, organizational
networks and shared information (such as languages,
processes, metrics, prices, policies, and laws)
designed to deliver services that satisfy the needs,
wants, or aspirations of customers.
5. Characteristics of Service Systems
•
•
•
•
•
•
Large and complex systems
Software intensive (several million lines of code)
Capabilities-based rather than platform-based
Organization and governance (human factor)
Technical performance is a prerequisite for production and
delivery of services, not a final objective
Requirements related to operations, in addition to technical
ones, assume a very high relevance:
Quality of Service (QoS)
Reliability, Availability, Continuity
Maintainability
Safety
Security
5
Flexibility
Expandability
Interoperability
Resilience
7. Large and Complex Systems (1/2)
• A large and complex system is a system composed of a
•
large number of interconnected elements, often developed
and deployed worldwide, which interact dynamically, giving
rise to emergent properties
Examples of complex systems supporting services for civil
applications include:
7
global satellite navigation systems
air traffic control systems
railway control systems
space systems such as the International Space Station or space
transportation and exploration vehicles
surveillance, Earth observation and Homeland security systems
electric power distribution systems
telecommunication systems
complex computer networks, including Internet.
8. Large and Complex Systems (2/2)
•
•
•
8
A complex system often integrates existing systems (or
parts of them) in an overall large-scale architecture
containing a large number of interfaces and implementing
multiple modes of operation, in a highly dynamic
environment
Large and complex systems require extensive logistics and
maintenance support capabilities
Large and complex space-based systems (e.g. Galileo)
are conceived to be in service for a long time; in this case
the evolution of the system (up-gradings and
modifications) has to be taken into account from the
beginning.
9. Specifying a Service System
•
•
•
•
9
Functional and technical performance:
System Requirements Document (SRD)
Operational requirements and scenarios:
Concept of Operations (CONOPS) document
Expected service behavior and non-functional
performance:
Service Level Agreement (SLA)
A typical SLA defines Key Performance Indicators (KPI’s)
and Key Quality Indicators (KQI’s), with target values and
target ranges to be achieved over a certain time period.
10. New Procurement Approach
•
•
•
•
Current systems engineering, project management and
acquisition practices still rely on their historical hardware
engineering and acquisition legacy;
Product-oriented, fixed-price, build-to-specification
contracts give the illusion of a delivery within the
allocated budget, but usually result in cost and schedule
overruns;
Many projects have difficulties integrating hardware,
software and human factor aspects;
Many projects fail to capture (and optimize) in their
acquisition processes the multifaceted aspects of the
systems they try to realize.

11. What is Galileo?
• EGNOS and Galileo are the key elements of the European
•
•
•
navigation “system of systems”, a strategic and critical
infrastructure of the European Union;
The Galileo global navigation satellite system, joint initiative by
the European Union and the European Space Agency, is one of
the most ambitious and technologically advanced service
systems being developed in Europe, by European industries and
with European resources;
While the system procurement and deployment proceed following
an incremental Implementation Plan, all steps are being taken for
the delivery of Early Services;
After a political decision of Vice-President Antonio Tajani, then
included by President Manuel Barroso in the agenda of the
European Commission, Galileo will start officially delivering Early
Services, i.e. the guaranteed and committed delivery of
capabilities to the community of potential customers/users, as
from the end of 2014.
16. Service means Commitment
“Je m’engage…”
The Galileo Early Services come from the political decision of VicePresident Tajani (then included by President Barroso in the agenda of
the European Commission) to start a guaranteed and committed
delivery of GNSS capabilities to users/customers in October 2014

17. Galileo Early Services: What?
Early services for OS,SAR and PRS will be provided
from 2014
Open Service (OS)
Public Regulated Service
(PRS)
Search and Rescue
Service (SAR)
Commercial Service (CS)
Delivery of a stable signal in space from a
number of satellites in orbit, allowing
ranging interoperable with GPS; time
broadcasting
Delivery of a stable secure signal in
space allowing Pilot Projects with EU
Member States
Guaranteed “forward link” which allows
the detection and localization of distress
signals; validation with Cospas-Sarsat
Initial demonstration projects with
potential service providers
The former “Safety-of-Life” Service
is being re-profiled:
Integrity Monitoring
Service
17
Provides vital integrity information
for life-critical applications

26. Services and "Spirit to Serve"
“Real Power is Service”
Pope Francis
“We serve our interests
best when we serve the
public interest”
T. Watson, Jr.
“Para servir, servir”
Josemaria Escrivá
“I slept and dreamt that life was joy. I awoke
and saw that life was service. I acted and
behold, service was joy”
Rabindranath Tagore
27. Conclusions (1/2)
•
•
•
•
•
Our economy is more and more depending on large,
strategic and complex service infrastructures, based on
large, strategic and complex systems;
The design of a complex service enterprise requires a
wide range of skills and expertise's, covering
organizational, engineering, social, legal and
contractual aspects;
A Services Science is indeed needed, but it has to
provide quick-winning and pragmatic answers;
The advent of a services economy imposes a radical
conceptual paradigm shift, more difficult to metabolize
than that required by a systems engineering
perspective;
The “spirit to serve” (call it “customer focus”, if you like)
is at the basis of all services.
