2. Process 3.1.3 has outputs but no
inputs. Unless
you are David Copperfield, this
is
a
miracle! In this case, the
input
flows were
likely
forgotten.
3. Process 3.1.1 the inputs are insufficient to produce the output. We call this a gray
hole. There are several possible causes including:
o
Misnamed process
o
Misnamed inputs and/or outputs
o
Incomplete
facts.
Gray
holes are
the
most common errors
–
and
the
most
embarrassing.
Once
handed to a programmer, the input data flows to a process (to be implemented as a
program) must be sufficient to produce the output data flows.
