I am a newly graduated mechanical engineer working for a small solar installation company. Right now we focus mostly on system installation but my boss is interested in expanding to manufacture some of our own products. He has some experience in manufacturing but not in engineering. Thus it will fall to me to develop the science behind our products.
Naturally I've taken some courses which discuss some of the methodology behind this but really there is no substitute for experience (which I lack).
My question to this forum is: How would you get started if you had to build a product from scratch? Where should I be spending my time?
