A. Functional Knowledge
Functional knowledge is what functions the product would
realize and how to realize them. The initial design intent of a
product is to satisfy the design requirements, and to realize the
required functions. Designers should use the knowledge they
have got and their experience to fulfill these functions.
Functional knowledge can help users understand the products
on the whole. What’s more it makes the designer’s intents and
the ways to realize their intents clear.
