Medro and Mariana were one day going through their OM notes from GUST. They were reading about the production system and looking at the production system diagram. Their notes were not complete because the professor talked too fast, so they couldnt write everything down. They were
looking at the dotted lines on the figure and wondered what they meant. If you were there with them, what would you say these lines mean?

a. information obtained from monitoring

b. information obtained from feedback

c. information of the standard to be followed

d. corrective action if needed for control purposes

e. none of the above
