Deck 3: Computer-Aided Design and Drafting Cadd

Question 1

Describe Web-based coordination.

Answer 1

. Web-based coordination uses the power of sophisticated PDM systems in conjunction with the Internet to simplify and streamline document management and team communications. Database management products allow designers, drafters, product suppliers, manufacturers, contractors, and owners to communicate and coordinate throughout the entire project, regardless of the location of each participant.

Question 2

Define product life cycle management (PLM).

Answer 2

. PLM is the method of managing the entire lifecycle of a product from the initial concept, through development and manufacture, to discontinuing or replacing the product.
