Solution 3

List down the elements of process model in hierarchical order:

State whether the following statements are TRUE or FALSE:

1.	A process stage usually operates independently from other process stages.	[	]
2.	A process operation describes a minor processing activity.	[	]
3.	In a process model, the procedure for making a product does consider the actual equipment for performing the various process steps.	[	]
4.	A process operation results in chemical and/or physical change in the properties of the material being processed.	[	]
