Create
a
Gantt
chart
from
the
work
breakdown
structure.
Create
a
PERT/CPM
network
showing
the
interdependencies
of
the
different
activ
ities.
How
long
will
the project
take?
(Note:Don’t
forget
to
take
“elapsed
time”
into
account.)
Using
the
information
in
your
Gantt
chart,
as
well
as the
information
on
wage
rates and
cost
of
materials,
put
together
a
budget
showing
planned
total
expenditures
for
the
project.
Following
are cost
and
schedule
data
for aproject
that
is
underway.
