Software Systems Installation

The following table lists country code and the order to remittance (OTR) time for a firm’s software installations
for the last 76 installations (from first to last). OTR is the time it takes after an order is received until the system
is installed and payment is received (remittance). Because this company does business internationally, it also
notes the country of installation using a country code. This code is listed in the first column.
