Data has emerged as the new currency, and businesses across industries are increasingly turning to data analytics to gain insights, make informed decisions, and gain a competitive edge. The banking industry, as a data-rich sector, stands to benefit significantly from leveraging data analytics tools and techniques. It is for this reason that this study looked at Analysing the Effectiveness and Usage data analytics in business management within commercial banks operating in Lusaka Zambia. A mixed-methods approach was used to gather comprehensive insights and a total of 100 employees from 10 different commercial banks in Lusaka made up the sample size. Regression analysis as well as descriptive statistics was used to establish relationships and give context to the observed data. The study observed that data analytics greatly improves banks' capacity to efficiently segment their clientele, enabling more specialised services and higher levels of customer satisfaction. The study also found that data analytics is essential for developing and visualising a number of indicators for the inefficiency of numerous internal and external processes and observed that data-driven insights should be increased as they enhance decision-making processes pertaining to risk assessment and mitigation techniques, which is crucial for preserving financial stability and compliance among institutions. It was observed that a well-educated workforce is essential to effectively leverage data analytics thus to optimise the use of data analytics banks should greatly improve their ability to make strategic decisions by emphasising ongoing professional development and incorporating analytical techniques into every aspect of company management.
