A company is trying to design new carbon monoxide detectors that register carbon monoxide at a level of 5 parts per million (ppm). The company engineers decide that the detector needs improvement and start designing new versions. They develop each new version based on new ideas and the features that worked in the previous one. They continue testing each new version in the process. Which process does this best describe?

A company is trying to design new carbon monoxide detectors that register carbon monoxide at a level of 5 parts per million (ppm). The company engineers decide that the detector needs improvement and start designing new versions. They develop each new version based on new ideas and the features that worked in the previous one. They continue testing each new version in the process. Which process does this best describe?

making trade-offs

the iterative design process

process and system optimization

evaluating advantages and disadvantages

the iterative design process

Explanation:

The Iterative design is a circular design process which comprises of models that are regularly evaluated and improved  based on the results of testing of previous models or versions.

Hence, when the company is involved in developing a new version of the carbon monoxide detector by evaluating the older  versions and continue testing each new version, they are involved in the circular process of iterative design.
