Think

jumps,

in

...
and

use

loops
...
for
...
the
...
cyclic
...
development
...
process
...
of
...
the
...
IMS
...
The
...
IMS-manual
...
is
...
aimed
...
at
...
guiding
...
the
...
user
...
through
...
the
...
whole
...
megasite
...
management
...
process;
...
from
...
the
...
initial
...
screening
...
to
...
the
...
final
...
definition
...
of
...
the
...
remediation
...
scenarios
...
and
...
long-term
...
site
...
management
...
plan.
...
The
...
IMS-manual
...
helps
...
the
...
user
...
to
...
distinguish
...
the
...
areas
...
of
...
the
...
megasite
...
with
...
the
...
highest
...
risk
...
and
...
set
...
up
...
priorities
...
for
...
the
...
level
...
of
...
risk
...
reduction,
...
degree
...
of
...
decontamination
...
and
...
consequently,
...
related
...
investments
...
on
...
the
...
basis
...
of
...
risk
...
assessment
...
for
...
the
...
area.
...
This
...
process
...
can
...
often
...
minimize
...
the
...
costs
...
of
...
the
...
project
...
and
...
maximize
...
its
...
effectiveness
...
by
...
channelling
...
investments
...
into
...
the
...
most
...
endangered
...
areas
...
of
...
the
...
site.
...
To apply risk-based
...
management
...
at
...
the
...
specific
...
megasite
...
the
...
user
...
is
...
advised
...
to
...
follow
...
the
...
stepwise
...
sequence
...
given
...
by
...
the
...
IMS-manual.
...
The
...
"big
...
jumps"
...
are
...
the
...
four
...
different
...
sections,
...
listed
...
at
...
the
...
left.
...
These
...
sections
...
are
...
subdivided
...
by
...
different
...
steps.
...
In
...
practice
...
the
...
user
...
may
...
find
...
him/herself
...
looping
...
back
...
to
...
earlier
...
steps,
...
in
...
order
...
to
...
use
...
new/better
...
information
...
or
...
new
...
insights.
...
The
...
IMS
...
provides
...
information
...
and
...
guidance
...
but
...
does
...
not
...
dictate
...
the
...
final
...
outcome
...
of
...
the
...
process.
...
The
...
IMS
...
is
...
structured
...
as
...
a
...
multi-level
...
approach.
...
It
...
provides
...
sufficient
...
information
...
to
...
the
...
technical
...
megasite
...
managers/site
...
owners/stakeholders
...
to
...
judge
...
upon
...
applicability
...
of
...
the
...
IMS
...
on
...
the
...
particular
...
megasite.
...
Detailed
...
information
...
and
...
reference
...
to
...
decision-support
...
tools
...
are
...
available
...
for
...
the
...
technical
...
experts/consultants
...
to
...
carry
...
out
...
specific
...
tasks
...
needed
...
to
...
establish
...
an
...
integrated
...
risk-based
...
management
...
plan.
