Choosing your production process
As you begin to consider your options for manufacturing
your new product, you might be surprised by the various
choices you can make . Of course, if you are ready, willing
and able to jump in with both feet, you can start and run
all of your own production processes . But you also have
the option of outsourcing either some or all of the steps
of production .
As an alternative to beginning a manufacturing operation
from scratch, you may want to work with other people
or businesses that can perform some of the operations
in the process . Perhaps you want to have various parts
made for you by other parties while retaining for yourself
the responsibility for assembly of the final product . Or
perhaps you want to make parts that can be assembled
by someone else .
You will want to structure your
methods of production in
a way that makes sense for your product . You can choose
between three basic methods of end-to-end production —
the job method, the batch method and the flow method .
Or you can segment the processes among various parties
or enterprises in a flexible manufacturing network .
End-To-End Production.
Here are your options:
•
Job production
calls for one person, or a few persons
working together, to perform the entire production
process . For example, teddy
bear production can be
done by giving one worker all the necessary raw materials
and tools to make a teddy bear from start to finish .
•
Batch production
, on the other hand, allows for more
specialization, and there may be different workers
doing different tasks as batches of parts or pieces are
completed . With our teddy bear example, one person
may cut the cloth, another may sew, another may stuff
the bear, and another may attach the eyes and nose . This
might be done in batches so that bears can be produced
in different colors and designs .
•
Flow production
can be visualized
by thinking of your
typical assembly-line system . The product is built up
through many segregated stages, and after each stage
it is passed directly to the next stage where it is built up
again . It is similar to batch production, except that it is
typically broken down into smaller, simpler tasks that are
performed by different workers one right after the other
(or performed by machines along an assembly line) .
Henry Ford introduced this style of production to the
automobile industry .
•
Manufacturing Process Management
(MPM) is a collec-
tion of technologies and methods used to define how
products are to be manufactured . A cornerstone of MPM
is the central repository for the integration of all these
tools and activities, which aids in the exploration of alter-
native production line scenarios . This can make assembly
lines more efficient with the aim of reduced lead-time to
product launch, shorter production times and reduced
work-in-progress inventories, as well as allowing rapid
response to product changes .
Flexible Manufacturing Networks.
Doing it all on your
own isn’t always the best option . Collaboration with other
companies can often achieve
better economic results
than going it alone . Flexible manufacturing networks
allow businesses to develop joint solutions for shared
challenges/opportunities . Networking firms can combine
resources to gain economies of scale; share knowledge,
technologies and resources; and enter markets beyond
their individual capability .
Large firms often outsource some component fabrica-
tion and sub-assemblies to improve their flexibility in
meeting customer requirements . Consequently, they
look
for smaller, specialized producers to supply their
