Chapter 5, a variety of ways to organize processes, known as general
layout types, are discussed. One of the most common is the
process-oriented layout, also known as a functional or jobshop
layout. Washburn
Guitars, manufacturers of over 150,000 guitars,
banjos, and mandolins, annually, provides an excellent example of a process-oriented
operation or job shop. |

| A very traditional departmentalized layout is used at Washburn and
it allows them to produce guitars
ranging from one-of-a-kind custom instruments to batches of standard
products. This approach is a great example of a classic intermittent flow |

| The functional departments at Washburn provide excellent examples
of the result of this type of layout.
Each is quite specific in what it is
capable of doing. The departments perform those specific tasks, however,
on a variety of products. Washburn’s
painting department, for example, is capable of painting and finishing any
of its products. |

| Likewise,
it’s assembly and testing department can assemble and test any of its
broad range of products |

| Like
many process-oriented businesses, Washburn sometimes must deal with queues
of products that build up in front of its work centers. Part of Washburn
management's challenge is to schedule the orders in front of Washburn’s
various functional departments. Different
priority rules are used to maintain order due date performance and to
provide guidance to employees managing the queues. The task of identifying
priorities, and occasionally interrupting them because of emergencies and
rush orders, is a critical part of managing the flow of orders in a job
shop. |

| Many job
shops have incorporated technology as a means of achieving a balance
between volume and flexibility. Washburn utilizes a very expensive Computerized Numerically
Controlled (CNC) machine to drill holes for the fret boards, bodies, and
electronic for all of the guitars.
This machine, a workcenter all by itself, is like
any expensive asset in that it needs to produce high quantities in
order to spread out its cost and maintain an economical cost per unit
produced. |

| Many job
shops strive to gain the type of flexibility and speed that can be
achieved through the use of a CNC machine. This type of manufacturing is
often referred to as a flexible manufacturing system. |
