SEQUENTIAL AND CONCURRENT ENGINEERING
Sequential engineering is a
linear process in which each
step of the engineering process
is performed in a specific order.
It typically involves a single
engineer working on a single
task at a time.
Concurrent engineering is an
iterative process in which
multiple engineers work on
multiple tasks at the same
time.

20. SEQUENTIIAL ENGINEERING CONCURRENT ENGINEERING
Sequential engineering is the term used to
describe the method of production in a linear
format.
Concurrent engineering is a non-linear product
or project design.
Different steps are done one after another. Several teams within an organization work
simultaneously to develop new products and
services.
After it is completed it is left alone and
everything is concentrated on the next task.
Different task are tackled at the same time and
not necessarily in the usual order.
Time consumption for marketing is more. Time consumption for marketing is less.
Decision making done by only group of experts. Decision making involves full team involvement.

COMPUTER AIDED DESIGN
Computer-aided design (CAD) is a way to digitally create 2D drawings and 3D
models of real-world products before they're ever manufactured. With 3D CAD, you
can share, review, simulate, and modify designs easily, opening doors to innovative
and differentiated products that get to market fast.

COMPUTER GARPHICS
Computer graphics refers to a
technology that generates images
on a computer screen. It's used in
digital photography, film and
television, video games, and on
electronic devices and is
responsible for displaying images
effectively to users.
