1 - THE DEVELOPMENT PHASE
The entire design team then sets off to conduct a second test, called "the field development test," accompanied by internal and external ambassadors, and hiking enthusiasts.
This involves testing the bag's basic functions and features and choosing between 2 versions.
When the team returns, it formalises the technical requirements and then Luc, the prototypist, produces a 2nd prototype.
The team then goes to China, where the bag is produced, so they can incorporate any industrial constraints into the planning process.
