Results of the study showed that in the home garden industry companies like MMI have tried using MIS and has seen good results, the MIS managed to bring about improvements on the business processes of MMI in terms of customer satisfaction, operational management and financial investment. MIS increased the motivation of the employees as it reduced the burden of the workload. The customers are satisfied with the use of MIS, it also save time and has reduced discrepancies and mistakes caused by human error. The MIS helped the MMI's employees accomplish their tasks quickly and more effectively.
