For this purpose, the study is designed in four parts. In the first part of the study; qualifications of information and quality of information, in the second part; information on cost management and strategic cost management issues are given. In the third chapter, national and international academic studies on strategic cost management and information quality are presented and the study methodology is explained. In the last part of the study, the data were analyzed using the SPSS 29.0 program. Questionnaire method was used as data collection tool in the study. The scope of the study consists of businesses whose shares are traded in Borsa Istanbul in 2019-2020. In this context, a questionnaire was applied to 216 enterprises. The reliability analysis of the obtained data was calculated with the Cronbach Alpha method. For the descriptive statistics of the study; frequency analysis, in statistical analysis; independent samples t-test from parametric tests, one-way analysis of variance, post-hoc analysis-tukey test; Chi-square independence test was used from non-parametric tests. In order to test the research model, multiple regression analysis was performed and the results of the hypotheses were given. As a result of the research, it has been revealed that enterprises mostly use the normal costing method (80.1%) from the traditional cost management systems, and the kaizen costing approach (56.9%) from the strategic cost management approaches. However, the most important obstacles to the use of strategic cost management approaches by the companies participating in the research are; lack of support from top management for activity-based costing and kaizen costing; for the target costing and quality costing approach, the firm's product/service structure is not suitable; for the just-in-time costing approach, it has been determined that there is insufficient knowledge of the personnel for the costing approach, and a lack of knowledge about the methods for the product/service life cycle costing approach. In the companies participating in the research, the statements of financial position and the profit or loss and other comprehensive income statement for the period are the tables most used in the decision-making process; top management is informed about costs, usually monthly; businesses have more ability to separate costs directly and indirectly; businesses obtain more product and activity-level cost information; with the cost management system/approach they use, businesses can calculate cost deviations of activities and direct labor wage/time deviations at a higher level than other production cost deviations; that the level of implementation of the cost leadership strategy of the enterprises is higher; information management processes are generally considered 'important' for businesses; it has been determined that businesses see increasing profitability with an effective cost management as the most important factor and that businesses benefit positively from the cost system/approach and information quality dimensions they use. In addition, while the most important information expected to be obtained by cost management in enterprises was about 'preparation of budgets', the information provided by the cost management used by the enterprises at the highest level was about 'control of costs'.
