Abstract
The
complexity
of
software
development
projects
makes
estimation
and
management
very
difficult.
There
is
a
need
for
improved
cost
estimation
methods
and
new
models
of
lifecycle
processes
other
than the
common
waterfall
process.
This
work
has
developed
a
new
simulation
model
of the
spiral
development
lifecycle
as
well
as an
approach
for
using
simulation
for
cost
and
schedule
estimation.
The
goal
is
to
provide
a
tool
that
can
analyze
the
effects
of a
spiral
development
process
as
well
as a
tool
that
illustrates
the
difficulties
management
faces
in
forecasting
budgets
at the
beginning
of a
project
which
may
encourage
more
realistic
approaches
to
budgetary
planning.
A
new
discrete
event
process
model
of the
incremental
spiral
development
lifecycle
approach
was
developed
in
order
to
analyze
the
effects
this
development
approach
has on the
estimation
process
as
well
as
cost
and
schedule
for a
project.
The
input
data
for the
key
variables
of
size
,
productivity
, and
defect
injection
rates
in the
model
was
based
on
analysis
of
Software
Engineering
Laboratory
data
and
provided
for
analysis
of the
effects
of
uncertainty
in
early
project
estimates.
The
benefits
of
combining
a
separate
system
dynamics
model
with a
discrete
event
process
models
was
demonstrated
as was the
effects
of
turnover
on the
cost
and
schedule
for a
project.
This
work
includes
a
major
case
study
of a
cancelled
NASA
software
development
project
that
experienced
cost
and
schedule
problems
throughout
its
history.
Analysis
was
performed
using
stochastic
simulation
with
derived
probability
distributions
for
key
software
development
factors.
A
system
dynamics
model
of
human
resource
issues
was also
combined
with the
process
model
to
more
thoroughly
analyze
the
effects
of
turnover
on a
project.
This
research
has
demonstrated
the
benefits
of
using
a
simulation
model
when
estimating
to
allow
for
more
realistic
budget
and
schedule
determination
including
an
interval
estimate
to
help
focus
on the
uncertainty
of
early
estimates.
