Using JMP Graph Builder, we plotted the total number of transactions against months of 2016-2017 (e.g. January 2016 coded as period ‘1’, January 2017 coded as period ‘13’)
From Figure 5, we discovered a sharp increase in number of approved transactions processed during the from January to October 2016. After that, there was an overall decrease in number of approved transactions, with sudden dips in November to December 2016, and April to May 2017. Additionally, the number of rejected transactions has been increasing towards the end of 2017. This signals potential issues, and exploratory analysis was conducted to assess performance of merchants contributing to the less optimistic trends towards end of 2017.
