This stepwise approach to mastery of a craft, which includes the attainment of some education and skill, has survived in some countries to the present day. But crafts have undergone deep structural changes since and during the era of the Industrial Revolution. The mass production of goods by large-scale industry has limited crafts to market segments in which industry's modes of functioning or its mass-produced goods do not satisfy the preferences of potential buyers. As an outcome of these changes, craftspeople today increasingly make use of semi-finished components or materials and adapt these to their customers' requirements or demands. Thus, they participate in a certain division of labour between industry and craft.
