Manufacturing Process Management allows you to manage manufacturing
planning and execution, using information generated in the design stage.
The manufacturing planning model includes several interrelated process and
operation types, as follows:

Manufacturing process
A set of manufacturing process operations and other manufacturing
processes that are closely related to each other. It is a mechanism to group
operations into logical groups. It also maintains constraints on the order
of execution between subprocesses and process operations.
The process structure is the model of the complete manufacturing plan,
and describes how and where the product is manufactured. It contains
information about which plant structure elements are used and where.
It establishes links between the product, plant layout, and the resources
necessary to produce the product.
Operations and resources can be shared by several processes. You can
define multiple views of a process to allow for different manufacturing
requirements.
You can also vary the generic bill of process (BOP) by defining and
applying variant or revision rules.

Process operation
A process operation represents one controlled step in the process and
contains the work done in one work area; technically, it is a leaf node
in the process structure. Optionally, you can break a process operation
into steps called activities. Examples of process operations include an
NC machining operation on a single machine tool and an operation to
assemble several components into a structure.

Operation activities
A breakdown of manufacturing process operations into activities, each
with an associated start time and duration. The total time of an operation
is calculated from the start time and duration of each activity.

Workstation
A unique location within the factory to which you can assign
manufacturing operations, for example, a paint spraying booth.

Plant
A manufacturing facility in which operations and processes are executed.
The plant structure is hierarchical structure of work areas of the factory
in which the product is manufactured. Its definition is independent of, but
related to, the manufacturing processes that are performed in it.

Work area
Any element in the plant structure such as a factory, line, section, work
cell, or station. Typically, a work area is assigned to one process operation.
A work area is defined by a location on the shop floor and the process
capability it provides.
To group resources further, your organization may define a hierarchy of
work areas. For example, a plant may include a welding line, a lathe
workstation, a milling workstation, and an inspection workstation. The
welding line may contain a welding workstation and a welding work cell.
You configure each work area with standard equipment, and you can
further configure equipment that is needed to execute a specific process
operation. The process designer tries to use as much standard equipment
in the work area as possible. If additional equipment is needed, the
process designer provides work instructions on how to configure the work
area with the additional equipment. For example, an NC machining
center may be pre-loaded with standard tools that are commonly used on
the machine. If a process operation requires tools that are not pre-loaded,
the operator loads them on the machine when the particular process
operation is executed.

Product structure
The product structure defines the as-designed product. It is created by
the design engineers in a CAD system such as NX® and managed by
Teamcenter. Manufacturing Process Management allows you to take the
as-designed product structure, create alternative manufacturing views of
the product and attach process definitions as necessary. (Optionally, the
product structure may contain definitions of manufacturing features.)

Operation setup
The model of an operation-specific configuration of an environment in
which processes and operations are executed. It describes how consumed
items, resources, and a standard work area are utilized to perform an
operation.

Consumed items
Components in the product definition that are consumed by a
manufacturing operation.

Consumed material
Items that are consumed by a manufacturing operation but are not part of
the product definition, for example, glue or paint.

Raw material
The initial in-process model before any manufacturing operation is
performed.

In-process model
The state of the product at some stage in the manufacturing process
after an operation is executed. The raw material is the initial in-process
model for the first process operation in the manufacturing process. Any
subsequent in-process model is created by attaching a work instruction to
the in-process model.

Resource
The equipment needed for the execution of manufacturing processes, and
may include machine tools, robots, and weld guns. A single resource can
be used in several operations and processes.

Work instructions
Documents that describe how work should be performed. A work
instruction documents the procedure by which an operator should perform
an activity. Instructions may be printable or accessed from a Web page.
Manufacturing Process Management allows you to create and manage work instructions in many of the applications. You can also create
templates to ensure work instructions appear in a standard format.

Manufacturing feature
A set of entities and parameters that define generic manufacturing data.
For example, a weld point and its normal location comprise a feature that
describes where two points may be welded together. All such features
should be associated with a process.
