Manufacturing by design is a fundamental part of the product. It involves optimizing product design for its manufacturing and assembly process, merging product design requirements with its production method. 

For an engineer, the design decisions and the manufacturing method are extremely important because from there, the manufacturing costs of a product are derived, and as we can all understand, the goal will always be to take them to the minimum possible. Therefore, focusing on design optimization benefits in reducing manufacturing costs. 

However, some engineers will follow the preset design to the end no matter if it is not the most appropriate. This means they never deviate from the structure and will follow it even if it fails or generates more costs.

This can lead to a bigger problem in the long run. Typically, during manufacturing design, there are times when it is necessary to deviate from the design or template, and when it happens, normally is because it was not designed for that particular equipment or environment.

Competition problems can also arise. I’ve heard of companies pushing their design to the point where they put the first-tier supplier out of business. And if that’s the case, why do they do it?  Some would say “They don’t see that their design doesn’t apply to all applications.” In the end, you need to deviate a bit from the design to make it fit or work in the required scope if you want it to be successful at the end of the day.

Overall, the manufacturing by design can be considered and developed in many different ways in order to ultimately produce the best quality product at the lowest possible cost. Therefore, if the design you carry out is done correctly and the changes you decided to make, make sense, the product will be the right one.
