Strategies for EVALUATION

Why do designers evaluate their work ?

Designers evaluate their work for a number of reasons.

1. To find out how successful their products are.

2. To find out if it is possible to improve their products.

Producers and designers attempt to improve their products continually in

order that they are the most successful products on the market.

Can you think of products that are continually improved?
