Final answer:
The question seems to refer to labor productivity factors, with technological change being a major driver. While the exact acronym 'L2R' is not defined, it likely pertains to improvements or updates in a technical field, which can be driven by reliability, innovation, and collaboration among technicians.
Step-by-step explanation:
The three technician drivers that directly impact the L2R update involve technological change, which is defined by a combination of invention and innovation. Technological change, such as the development of the transistor, has greatly improved labor productivity by enabling the miniaturization of electronic devices, reducing power consumption, and facilitating better communication and efficiency among workers. With this context, it is reasonable to infer that the drivers that most directly impact such updates could include aspects like Reliability, Innovation, and Collaboration; however, without specific context for L2R in the question, it is challenging to identify the exact three drivers from the provided options. It is important for technicians to keep up with technological advancements and also possess soft skills, such as good communication, that complement their technical skills.
