The "Final Build" section of the Creative Engineering Design Process is meant to evaluate the results of all your work from the perspective of marketing - how to get your product into the eyes and hands of your customers
This means taking a step back and ensuring you have no strayed too far from your original product requirements and desired outcomes
Additionally, performing final testing of your product not just from a functionality standpoint but also from usability, marketability, longevity, and all other perspectives of product analysis
The results of the "Final Build" portion of Creative Engineering Design Process should be a marketable product
Focusing on specific markets rather than trying to universally appeal to everyone is a fundamental principle in product marketing for several compelling reasons. This targeted approach is often encapsulated in the concept of "market segmentation" and is critical for the efficient allocation of resources, maximizing marketing impact, and ultimately achieving commercial success.
