It is worth noting that Smith did not advocate labor division at any price and "". The appropriate level of task division was defined through experimental design of the production process. In contrast to Smith's view which was limited to the same functional domain and comprised activities that are in direct sequence in the manufacturing process, today's process concept includes cross-functionality as an important characteristic. Following his ideas, the division of labor was adopted widely, while the integration of tasks into a functional, or cross-functional, process was not considered as an alternative option until much later.
