Table $1\mathrm{.}2$

The GE electrical assemblies. There is currently a process in place that uses $10$ operators to produce $200$ units per hour of product X$.$ On your first day of work, an operator tells you that the current process needs adjustment. You are thinking about whether to change the current process with new assembly methods that increase output to $300$ units per hour. However, the new method requires $14$ workers. You have the following:

$$ CURRENT PROCESS NEW PROCESS

OUTPUT $($UNITS $/$ HOUR$)200300$

NUMBER OF WORKERS $1014$

MATERIAL COST $/$ HOUR $$120$ $$150$

Workers are paid $$10$ per hour, and the overhead is $140\%($or $1\mathrm{.}4$ times$)$ of labor costs. Finished product X sells for $$20/$ unit. Use the information provided in Table $1\mathrm{.}2.$ What is the multifactor productivity of the current process?
