12.1: Introduction

As described in Unit 1, one of the most important parts of the engineering design process is iteration.  Once a design has been completed and a solution implemented, the solution must be tested and improved until it is acceptable.  This improvement is done using the process of iteration, where steps of the design process are repeated over and over (iterated) to produce the best result.

Students should review Step 11 of the Engineering Design Process from Unit 1 for more details on iteration.
