Analyze the diagram and look for errors:

a$)$ Look for omissions $-$ what should be there but is not? Omissions could be whole symbols, labels or parts of labels.

b$)$ Look for unnecessary elements $-$ what is there that should not be$?$ The diagram may need minor remodeling.

c$)$ Look for correct usage of elements $-$ what elements are not being used in the correct way? In what way should they be used?

d$)$ Look for proper responsibility $-$ what activities belong in what place? Where should they be$?$

e$)$ Look for correct logic$/$flow$/$use of elements to describe the business process $-$ does the flow make business$/$logical sense?
