Womack, Jones and Roos in the book The Machine That Changed the World detailed that early automobiles were craft produced.
For example, in some mass-production automobile manufacturing facilities, craftsmen rework flawed, mass-produced vehicles to give the appearance of a quality product.
The production of many crafts have a high technical demand, and therefore require full-time specialization of the skill-set in the form of workshops, or verbal, hands-on training.
Craft-specialization explores how portable goods are integral to the social relations of a community, and links groups of people together through the creation of tangible items.
[4] These communities are often tight-knit, with strong linkages to materials produced and sold, as well as mutual respect for fellow tradesmen in the market place.
