How Lego builds a new Lego set
https:/
In addition to production, packing, packaging, and marketing, Lego has a host of teams that work directly with designers, including a function testing department, a safety department, an engineering department, and a textile department. There’s even a dedicated “building instructions” department and a “model quality” team, each of which sits with designers and watches them build. They make sure the build process stays fun, the instructions make sense, and the model stays stable enough that there’s little chance it breaks while you build it.
