Stephanie Essington, staff benefits specialist,
has recently completed a thorough training
program in employee benefits counseling and is
eager to put her newfound knowledge to good use
in her company. Her company has recently adopted
a new medical benefits package that offers
several choices with regard to levels of
coverage, flexibility of benefits, deductible
level, and range of services and providers.
Stephanie is not new to this type of counseling,
but the previous medical benefits program was far
less complex than the new one. Since completing
her training, Stephanie feels confident that she
can explain all of the options available to the
employees, but she is finding that most of the
employees she has counseled so far have not been
excited about the new system. They seem to be
struggling with the many options and combinations
of benefits, and Stephanie feel she needs to be
much more specific with regard to her suggestions
to employees. She is considering developing a
computer program that would allow her to create
multiple scenarios ranging from worst case to
best case for each employee. Shortly after
beginning her detailed analysis for this
application, she runs into several roadblocks.
Her requests to the IS department for employee
salary and personnel data are taking up to a day
for responses. Further, she is finding that much
of the information she receives is outdated or
even conflicting. Finally, the calculations
necessary to perform this scenario analysis are
quite complex, and although she is a fairly
proficient spreadsheet user, she fears that the
development of the application may be a little
beyond her programming skills. She knows that a
slight flaw in the calculations could have a
major negative effect on the decision process.
