The research aims to study how capital management affects the economic performance of manufacturing firms. The study aims to examine the relationship between liquidity, measured by working capital (WC), and company viability, measured by Return on Total Assets (ROTA). The investigation is important as it can help managers find a balance between liquidity and business performance. The study uses secondary data from various national and international sources such as publications, books, and research papers. The research paper aims to assess how (WC) impacts the sustainability of businesses. Correlation analysis and regression analysis are commonly used statistical techniques to study the relationship between variables. These methods allow researchers to examine the relationship between multiple variables and determine its nature and strength. Regression analysis is a method used by researchers to determine how one variable predicts or influences another. Correlation analysis allows researchers to measure the strength and direction of the relationship between variables without implying causation. Regression analysis and correlation analysis are important tools in empirical research that help understand the relationship between variables and aid in data interpretation. The study examined the relationship between a dependent variable and ROTA using regression analysis, as well as a set of independent variables. The study examines several independent variables, including the ratio of current assets, the rapid ratio, the inventories turnover rate ratio, the liquidity ratio, the revenue ratio, the total assets ratio, and the net assets ratio. Regression analysis is used to determine the relationship between ROTA and independent variables. Correlation analysis, or correlation study, is a statistical method used to measure and assess the relationship between two variables, while considering the influence of other factors. (WC) is crucial for businesses as it enables them to manage daily operations, cover regular payments, handle unexpected expenses, and purchase necessary manufacturing inputs. The study aims to emphasize the importance of effective (WC) management in various organizations and its impact on profitability. Managing (WC) effectively is crucial for efficient operations and can lead to increased revenue and profitability for a company (Smith, 2019). Jones et al. published a study in 2017. Effective (WC) management is crucial for businesses as it allows them to optimize cash flow, mitigate liquidity risks, and improve financial performance. Effective (WC) management practices can improve a company's profitability by reducing financing and inventory holding costs and improving its ability to meet short-term obligations (Brown & Howard, 2015). Businesses need to focus on effective (WC) management strategies to improve financial performance and achieve sustainable growth (Johnson & Smith, 2020). The research highlights the importance of various aspects of (WC) management, including supply administration, receivables management, inventory management, and payable management.
