Advantages of Concurrent
Concurrent Manufacturing manufacturing
What is concurrent manufacturing?
Reduces time to market
All of the key people who work at each stage of the design and
manufacturing process working together to make sure that changes to Reduction in design modifications
one part of the process will not require changes to be made to another,
making sure the product is right the first time. Decreased design and manufacturing
· Aims to eliminate the need for design changes Improved product quality
and overcome production problems
Enhanced customer satisfaction
Flexible Manufacturing System
2 main features of FMS Advantages of FMS

manufacturing resources .
What is flexible manufacturing system?
Where several machines are linked together by a material-handling system such as computer-controlled robot .It brings
together new manufacturing technologies such as CNC or robotics to form an integrated system. Its different from an
automated production line because of its ability to process more than one type of product at the same time.…read more

"House of Quality" matrix
· Early in the development stage of a product, designers can use a function called
Quality function deployment (QFD) in order to create a more successful product.
QFD is a method that incorporates customer satisfaction into the development of
a product before it is manufactured
· A "House of Quality" matrix is used to translate customer requirements into a
number of targets to be met by the product.
Component Content
1. Customer requirements A list of requirements from customers doing customer surveys.
2. Technical requirements A technical specification is produced.
3. Planning matrix A plan of what the product needs in order to meet customer and
technical demands.
4. Interrelationship matrix A grid showing how technical requirements join with customer needs.
5. Technical correlation An analysis on how various requirements either support or contradict
each other, If contradictory then a compromise is needed.
6. Technical priorities, benchmarks, Quality targets against each technical requirement can be measured.

1. Product data management systems(PDM)
How does it work?
What is Product data management?
An information system used to manage the data for a Once the designer is satisfied with
product as it passes from design to manufacture. The data the component, the PDM system
includes plans, 3D models, CAD drawing, CNC will notify the next person to
programmes etc. A PDM also highlights when changes are perform their task on the product
made to one database so that any effects on other parts and once they are done they will do
can be determined. an electronic sign-off. The PDM
system will then notify the next
person and so on.
Advantages of Product data management
Reduced time to market as data is instantly available to all teams
for review where documents await sign-off
Improved productivity as changes to data are tracked and
managed automatically, reducing the time to search for
