Northwestern
Mutual, its subsidiaries and affiliates offer insurance and investment products
and advisory services that address client needs for financial protection,
capital accumulation, asset distribution and estate preservation. Products
include permanent and term life insurance, disability income insurance,
long-term care insurance and annuity plans for personal, business, estate
planning and pension markets; trust services; mutual funds and other
securities. Northwestern Mutual Financial Network is the sales and distribution
arm of the company, with more than 350 sales offices and 7,800 financial
representatives across the United States.
The company’s home offices are located in Milwaukee, Wisconsin where about
4,400 corporate employees reside. This campus comprises three buildings. The
oldest was built in 1912, the newest was built in 1990. A new campus in
Franklin, Wisconsin is scheduled to open in 2004.
There are many functions of the company that require Northwestern Mutual’s
employees to come together in a timely fashion every day, including extensive
training programs for finanicial representatives and employees, call center
representatives, as well as conferences and meetings.
On any given day in the corporate headquarters, there are approximately 600
scheduled meetings that occur. These meetings may include anywhere from three
to thirty people. There are 153 conference rooms spread throughout the
facility. The flow of people through those spaces is managed through a central
software program. It is important that meetings start and finish on time in
order to keep the flow of business smooth, efficient, and productive.
A hard-wired synchronized clock system was installed in all Northwestern
Mutual’s buildings during a renovation that occurred in 1976. Through time the
number of company clocks in the system grew to about 350 throughout the
facility, six to a floor, hung so that everyone in a given work area could see
them. The idea was that everyone would have the correct time and no one would
have the clocks to blame for tardiness to a meeting.
All of the wall clocks in the hard-wired system were connected to one another
and to a “master” unit via electrical conduit. They were synchronized to each
other when the master delivered an electrical impulse periodically throughout
the day.
While this was a good idea and worked for a while, it was an imperfect system.
The rate of failure among the clocks throughout the building was high and
synchronization from one building to another was consistently off by up to five
minutes.
The clocks used in the system were older mechanical clocks (as opposed to
quartz cloks that are now considered standard). So the drift factor, or time
that clocks would lose between synchronization signals, was high. At any given
moment in time about 25%, or more than 85 of the clocks in the system, were off
by three to five minutes. And the further away from the master, the less strong
the signal, which also affected the time drift for clocks in an entire zone of
the building.
When the time changed twice a year the master would convey the revised time. At
those times there were about 50 clocks that failed to make the change. If a
manager wanted to hang another clock within his/her work area there would be
debates about where the clock could be placed or the expense related to
extending electrical conduit to the new location.
Maintenance expenses were incurred to monitor the clocks throughout the
building daily, to reset the 85+ that were off every day, to repair mechanical
movements that wore out, to install additional clocks, and to reset clocks that
failed to “spring forward or fall back” when the time changed. Nerves were
frazzled as meetings would start late, productive time was wasted, and business
managers registered daily complaints to facilities managers about clocks not
keeping time.
In sum, synchronized time was a good idea, but the time system they had was
causing grief, costing the company money in terms of maintenance and lost
productivity, and was diverting managers’ attention from more important issues.
In 2000, Northwestern Mutual saught a better solution to alleviate the issues
of an imperfect time system. The company approached Primex Wireless, which is
part of a 30-year-old company specializing in the clock industry as well as an
innovator in wireless synchronized time solutions.
Primex had pioneered the development of wireless analog clocks using radio
frequencies in the United States. Northwestern Mutual was one of the first
customers to implement the Primex Wireless GPS Clock System, the most precise,
most reliable wireless synchronized clock system available.
The system consists of a master unit, which includes a GPS receiver, a 16 x 12”
casing, and a 46” high FM antenna, and the freestanding, battery-operated
analog wall clocks. The master captures the official time signal from US Global
Positioning Satellites and transmits the time to the clocks via a local FM
frequency. You can have as many clocks in a system as you need. There is no
load diminishment for the number of clocks. The area that the transmitter
covers may vary depending on the building and other frequency interferance
factors such as rf-shielded rooms or terrain.
Northwestern Mutual installed its master unit in an inconspicuous location in
the atrium of its main building and the clocks were hung right over the
junction boxes where the old hard-wired clocks were previously positioned.
Installation of the system was easy and accomplished in only 10 days. Five
masters cover all 350 clocks that are spread throughout four buildings in the
headquarters campus, including clocks installed in the basement and
sub-basement.
Since the Primex Wireless GPS Clock System was installed, all 350 clocks in the
system have run in perfect synchronization—to the second. The facilities
mangers are now freed up to attend to more important issues. Repair issues are
non-existant, the clocks never need to be adjusted, and they self-adjust for
Daylight Saving Time.
There is a large improvement for the facilities managers. According to Greg
Junek, Manager of Facility Technical Services, “We used to get 7 calls a week
from managers angry about clocks being off somewhere in the building. Now there
are none. And if someone is late to a meeting, they can’t blame the clocks!”
