From Prototype to Product - A Practical Guide for Electronic Engineers

Universities and colleges are very good at giving their students a solid grounding in the technology so that graduates can produce prototype designs that work. What they are not taught is how to turn those prototypes into commercial products that sell at a price that generates a profit for their companies.


“So I set out to help graduates by putting down on paper some of my experiences over the last 30 years. As well as talk about the successes I include many mistakes that were made and how these could have been avoided.”


Seggy T Segaran has been involved with product design for nearly 36 years. This book is based on the experience gained in launching more than 30 products in that period. He is currently Technical Director at Tele-Products Ltd, a company he founded more than 25 years ago.
