What is Design?
The word “design” is often used as a generic term that refers to anything that was made by a conscious human effort.
Design is also a process that is used to systematically solve problems.
Definition of DESIGN
transitive verb
1: to create, fashion, execute, or construct according to plan
: devise, contrive
2 a : to conceive and plan out in the mind <he designed the perfect crime>
b : to have as a purpose : intend <she designed to excel in her studies>
c : to devise for a specific function or end <a book designed primarily as a college textbook>
3 archaic : to indicate with a distinctive mark, sign, or name
4 a : to make a drawing, pattern, or sketch of
b : to draw the plans for <design a building>

What is an Engineering Design Process?
A design process is a systematic problem-solving strategy, with criteria and constraints, used to develop many possible solutions to solve or satisfy human needs or wants and to narrow down the possible solutions to one final choice.
