In manufacturing facilities, line supervisors monitor production lines and managers must
be able to contact each other and other employees immediately to check the status of
various operations and solve problems that regularly arise. A division manager in charge of a particular business unit, for example, is certainly anxious to ensure that the plant is getting
products ready to ship in time to make revenue numbers. If a part of the orders for that
period is at risk of not being completed in time, fixes can be considered and put in place to
keep manufacturing on schedule.
A VoWLAN system makes communications in manufacturing extremely beneficial
because managers are constantly on the move. In many cases, a manufacturing plant will
have an existing wireless LAN in place, making the deployment of a VoWLAN extremely
feasible. Even if the installation of wireless access points is necessary, the VoWLAN
solution is still worthwhile because of the monetary benefits associated with immediate
communications. In this situation, the value of the company to shareholders depends on
effective communication among stakeholders in the manufacturing process. A VoWLAN
solution allows managers to communicate immediately and solve problems to keep
production in line with sales.
Toy manufacturer benefits from a VoWLAN system
The managers at a toy manufacturer were having trouble communicating with each other.
For example, the manufacturing line for a particular toy would begin having mechanical
troubles, which would require the manufacturing line supervisor to shut down production
until someone could perform necessary repairs. This plant is large, and a single centralized
maintenance group takes care of many production lines. The line supervisor would use his
office phone to call the maintenance chief, who would then need to track down the right
mechanic to fix the problem. The issue was that "phone tag" would result, causing
significant delays. Often an hour or more would elapse before this coordination would be
done and a mechanic would be notified that he needed to work on the problem. Meanwhile,
the company would be losing $500,000 each hour the production line was shut down.
Something had to be done to speed up communications needed to coordinate maintenance
when problems arise on one of the production lines.
To solve the problem, this company installed a wireless LAN throughout the manufacturing
plant to support the use of VoWLAN phones. All managers, supervisors, and maintenance
staff were equipped with VoWLAN phones. A production line supervisor can now call the
maintenance chief directly via VoWLAN phones. The maintenance chief may be out of his
office assisting one of the mechanics and still be able to receive the call immediately. The
maintenance chief can use the VoWLAN phone to coordinate the right mechanic to fix the
problem. Because everyone carries the VoWLAN phone with them at all times, telephone tag
is no longer an issue, and communication is immediate. This time savings significantly
reduces downtime of the production lines, which in turn improves the company's profits.
