This chapter explores the concept of non-value-added operations in
manufacturing (NVAA; non-value-added-activities) and how it affects part design. In
the past, parts were designed to be functional to the mission they would serve, usually
without regard to ergonomics, assembly method, and efficiency, as in the aftermarket.
The idea is to describe what currently are considered operations that do not add value
to manufacturing and to show examples of applied design, giving an idea of how the
designer or engineer should think when manufacturing a new product. They should not
only focus on functionality but also on the process, always contextualizing the different
technologies available, the laws in force and the market to which it is intended to be
introduced.
