IRDBTC
1) Identify a need
2) Research a problem
3) Design a solution
4) Build a prototype
5) Troubleshooting and redesigning
6) Communicating the solution
Identifying the cause of any problems in a design is an example of
troubleshooting
An example of troubleshooting and redesigning used by early engineers when building the early computer mouse was
Steel ball changed to/was replaced with rubber because steel was noisy and dirt got in it.
After engineers identify the need they must
research the problem
A working model used to test a design is called a
Prototype
The first step in the technology design process is to
identify a need
