Explain why specialization leads to an increase in labor productivity?

Specialization is one of the most successful ways to increase productivity. Such high efficiency is due to the fact that, constantly performing the same work, people begin to do any manipulations faster. As a result, the rate of production of the same goods increases significantly. Also, the employee delves into the production process well and begins to notice his own mistakes and shortcomings. As a result, the quality of the goods produced improves and the value for consumers grows.
