Present here is a supply chain of a pharmaceutical company in the form of a sequencing flow chart. The entire diagram deals with how a drug is manufactured and reaches a patient passing through various channels along the way. In this particular diagram, we see two manufacturers- API and Excipient. Both are involved in manufacturing and packaging of the drug which is supplied to the primary wholesaler. The primary wholesaler in turn supplies to the secondary wholesaler. Next, the secondary wholesaler supplies manufactured drugs to hospitals and pharmacies and it finally reaches the patient. Such pictorial flow charts prove effective in explaining complicated and comprehensive information. In one glance all the details can be easily understood by anyone.
