Anesthetic gases called Desflurane supplied by distributor Company to the hospitals. These anesthetic gases transferred to the patients in a controlled manner via medical devices named Vaporizer (VAP) which are integrated to the anesthesia devices; used especially in operating rooms. Updated hospital VAP inventories are reported to the head office by the sales team on a monthly basis. By tracking the monthly gas consumption of the VAP's, we are calculating the efficiency of devices per hospital. Thus, the performance metrics of the sales team can be evaluated. Which device; belongs to which hospital and under whose responsibility, device manufacturing date etc. can he easily observed at first look. However, missing/false statements have a huge negative impact on inventory, efficiency and performance indicators.
