The next responsibility of many design engineers is prototyping. A model of the product is created and reviewed. Prototypes are usually functional and non-functional. Functional prototypes are used for testing and the non-functional are used for form and fit checking. This stage is where design flaws are found and corrected, and tooling, manufacturing fixtures, and packaging are developed.
Once the prototype is finalized, after many iterations, the next step is pre-production. The design engineer, working with a manufacturing engineer and a quality engineer reviews an initial run of components and assemblies for design compliance.This is often determined through statistical process control. Variations in the product are correlated to aspects of the process and eliminated. The most common metric used is the process capability index Cpk. A Cpk of 1.0 is considered the baseline acceptance for full production go-ahead.
The design engineer may follow the product and make requested changes and corrections throughout the life of the product. This is referred to as "cradle to grave" engineering.
These duties may also be shared with industrial designers depending on who is more qualified for each task.
