3. Introduc+on
• A
SoS
can
be
successful
only
if
its
cons+tuent
systems
have
business
strategies
and
technical
roadmaps
that
are
sufficiently
aligned
• Our
focus
of
study
is
Ecosystems
that
interact
to
form
the
ecosystem
of
the
SoS
• We
address
a
plaMorm-­‐based
SoS
• Systems
are
managerially
and
opera+onally
independent
but
are
designed
on
a
shared
plaMorm
of
common
services
3

4. Health
of
the
SoS
Ecosystem
• The
SoS
must
an+cipate
updates
to
the
cons+tuent
systems
and
will
feedback
bug
reports
and
change
requests
to
the
appropriate
ecosystems
• The
health
of
this
new
ecosystem
– The
confounding
effects
– Inter-­‐ecosystem
dependencies
4

5. Health
of
the
SoS
Ecosystem
• Produc6vity
– The
produc+vity
of
the
ecosystem
surrounding
a
SoS
is
+ed
to
the
produc+vity
of
the
ecosystems
surrounding
the
cons+tuent
systems
• Niche
Crea6on
– The
niche
crea+on
oTen
begins
in
the
ecosystem
surrounding
one
of
the
cons+tuent
systems
– A
new
niche
recognized
in
an
individual
system’s
ecosystem,
probably
will
be
judged
to
have
less
risk
than
at
the
SoS
level
niche
• Robustness
– In
the
SoS
ecosystem
with
rela+onships
to
several
different
ecosystems,
there
are
oTen
mul+ple
possible
ways
of
providing
a
specific
feature
5

6. Health
of
the
SoS
Ecosystem
• Cohesiveness
– The
cons+tuent
systems
in
an
SoS
must
fit
well
together
– Over
+me
the
individual
systems
evolve
and
may
require
addi+onal
glue
code
to
interoperate
6

7. Example
• Connected
Vehicle
Reference
Implementa+on
Architecture
(CVRIA)
– A
connected
vehicle
has
wireless
connec+ons
to
other
devices
– At
any
instant
in
+me
the
SoS
is
composed
of
interac+ng
traffic
infrastructure,
vehicles,
and
people
• Produc+vity
– There
are
a
large
number
of
infrastructure
products
designed
to
be
compa+ble
with
the
CVRIA
• Niche
crea+on
– The
CVRIA
ecosystem
is
crea+ng
a
number
of
new
research
ini+a+ves
in
the
area
of
safety
of
connected
vehicles
7

8. Example
• Robustness
– Government
ownership
of
much
of
the
traffic
infrastructure
ensures
that
the
ecosystem
will
remain
robust
further
encouraging
ac+vity
• Cohesiveness
– Exis+ng
traffic
regula+ons,
constraints
described
in
the
CVRIA
result
– Society
for
Automo+ve
Engineers
(SAE)
standards
ensure
the
cohesiveness
of
this
ecosystem
8

9. Challenges
• Community
Alignment
– Management
of
different
rules
and
behavior
standards
among
the
groups
in
the
individual
ecosystem
communi+es
• Management
of
Mul+ple
Markets
– The
ecosystems
should
support
the
SoS
and
other
applica+ons
and
be
present
in
different
markets
inside
and
outside
the
SoS
• Architectural
Decisions
– Architectural
decisions
must
be
separated
into
those
that
support
all
applica+ons
on
the
system-­‐of-­‐systems
and
those
that
support
only
those
applica+ons
within
a
single
ecosystem
– Management
of
all
dependencies
among
several
projects
to
sa+sfy
different
niche
markets
9

10. Conlcusion
• We
iden+fied
one
new
characteris+c
of
ecosystem
health
– Cohesiveness
• Cohesiveness
reflects
the
integra+ve
nature
of
the
SoS
and
its
ecosystem
• Future
work
– Do
addi+onal
literature
searches
– Do
interviews
with
engineers
designing
SoS
for
recurring
use
of
specific
criteria
for
evalua+ng
the
health
of
the
ecosystems
suppor+ng
a
SoS
