Minitab is astatistical software which is used to analyse data for quality improvement. Associated with Minitab are uniquely designed products which help professionals improve their business processes. This software is used by companies world-wide in order to deliver a quality product. Examples include Ford Motor Company, which used Minitab as a statistical tool to launch the Ford Fiesta; the Riverview Hospital Association Lean Six Sigma team used Minitab to perform data analysis to identify patient groups who were scoring lower on patient satisfaction survey question. Also, Boston Scientific’s medical device manufacturer used Minitab to analyse data that would validate the pouch-sealing process used to package guide wires. In this manuscript, we intend to compile an analysed data-based report for the sales of rice in Zimbabwe. The report is based on the data supplied by Afro Foods Management requesting the likely sales of rice in Zimbabwe for the first three months of 2011. We use Minitab to analyse the data and then fit the best Autoregressive Integrated Moving Average [ARIMA] model and Explanatory model built using the previous data of the sales of rice. The results showed that, for short periods, ARIMA model is the best.
