Final answer:
EPM generally stands for Employee Performance Management, a method to evaluate and enhance worker productivity online, which is related to productivity improvements brought on by technological innovations like the transistor.
Step-by-step explanation:
The abbreviation EPM commonly refers to Employee Performance Management, which is a modern innovation utilized by management to assess and improve the efficiency and productivity of their workers, especially in an online environment. While this exact abbreviation does not appear in the provided reference material, the concept of EPM is deeply connected to the broader topic of productivity and technological change, which is frequently driven by both invention and innovation. Indeed, it's technological innovations such as the development of the transistor in 1947 that have permitted vast improvements in labor productivity by enabling smaller and more energy-efficient devices that allow workers to operate effectively from virtually anywhere.
In measuring productivity, factors besides the amount produced per hour of work can include the quality of goods or services, customer satisfaction, the effectiveness of communication and collaboration among workers, and the degree of innovation. Technological change is cited as a key driver of productivity improvements, which reinforces the importance of innovations like those seen in the realm of employee performance management tools.
