Final answer:
The material cost per unit is not needed to compute equivalent units of production. Measurements imperative for this computation include percentage completion of work-in-process, units transferred out, and units started and completed. Other productivity measures include output quality, unit labor costs, and revenue per employee.
Step-by-step explanation:
The item not needed to compute equivalent units of production is D. the material cost per unit. When calculating equivalent units of production, the focus is primarily on quantifying the units in terms of their stage in the production process, not on their individual cost components.
Regarding other measures of productivity, metrics such as output quality, unit labor costs, and revenue per employee offer additional perspectives beyond the amount produced per hour of work. Such metrics can provide a more comprehensive understanding of productivity in various contexts.
