Design Need
1. In hierarchy of design need, functionality come first
before reliability. The design of the product must
meet basic functional needs even before being able
to perform consistently.
2. Later, Usability comes in to play. The term of usability
can be simplified as making a product easy to use.
3. Creativity is one of the last aspects of design in
hierarchy of design need. If the creativity criteria is
achieved although the criteria of useable, reliable,
functional product are not accomplished, the
product is still not acceptable in the market. It is
important to ensure that each criteria must fulfill
based on the biggest weightage at the hierarchy of
design need.
