Step-by-step explanation:
In the given scenario, Pho Nyguen, who is a manufacturing mechanic, identifies that the molds used for creating plastic jar lids are wearing out more quickly than expected. Upon this realization, Pho has taken the initiative to contact her manager to request a reorder of these essential parts. In this context, Pho has played the role of a monitor.
Monitors in a business environment are responsible for overseeing and assessing different aspects of the production process or operational workflow. They keep an eye on the status of equipment, the progress of work, and other indicators of performance or quality. When they identify an issue, such as prematurely wearing out manufacturing molds—which are essential for producing items like take-out trays, foam packaging peanuts, CD cases, foam-walled drink cups, and other thin-walled and moldable parts—it is their duty to report this to the relevant authorities within the company to ensure that the production process can continue smoothly without prolonged interruptions.
