“TechCo” Company is an online retailer of electronic devices with more than 100 000 customers. In order to enhance their customer service performance and increase revenue, TechCo established a new BI department to assist them in turning information into insights and then actions.
Core challenges being faced by the company were related to digging information timely from its database. TechCo was having multiple online application running on various database types, and a large extent of its data was fetched from excel sheets and files. They were looking for a data visualization solution that, apart from addressing these primary challenges, could also enable the company to know the status of its site-wise stock inventory, project-wise and site-wise stock value, part family-wise stock inventory and overdue invoices.
Ten years worth of transactions collected through their website, helped them to get insight into other products the customers are most likely to purchase. They identified them by classifying their customers using charts, and by exploring the existence of trends, concentrations and outliers. They designed dashboards with Visual Analytics and distributed them across all senior managers to monitor performance.
This data mining process was established using many steps: First they had to understand the business, and then understand the data, after that prepare the data, and then build the model, and finally deploy it.
