Chapter 19. Make design changes

Knowledge may give weight, but accomplishments give luster, and many more people see than weigh.

- Lord Chesterfield

By now you will have hopefully taken your product from early idea all the way to satisfying your first customer. You’ve learned a lot about the whole process, and probably, like I did, you’ve made a few mistakes along the way. I hope, none of them was serious. You have learned of a few defects relating to your product.

There is no time like the present to look at how those product defects might be addressed by making design changes to your product.

Although the first batches of your product satisfied your Version One objectives, it is possible some or all of the molds will have to be remade to address the product design problems you have discovered. Even if your first shot at design produced a good enough product, the next stage will be to lower the unit product costs by increasing the number of cavities.

You can look at this in one of two ways.

(a) Your product is good enough and making changes to the design might break it, or

(b) Since you are recreating the molds anyway, you should squeeze in a few needed improvements.

Only you can know which path to take, but I would err on the side of leaving the product alone and go off looking at your next product. But, if there are significant design issues with your product, then you may have no choice but to redesign the product. Just remember that, by fixing one problem, you may create another

Cost of this stage: $0. Costs so far: $77,800
