Process costing works well whenever relatively homogeneous products:

a$.$ pass through a series of processes and receive similar amounts of manufacturing costs.

b$.$ pass through a series of simultaneous processes and receive different amounts of manufacturing costs.

c$.$ pass through a single process with no ending work$-$in$-$process inventory.

d$.$ pass through a series of simultaneous processes, and manufacturing costs are incurred in the beginning of only the first process.
