This research paper presents a management proposal for McDonald's, outlining strategies to leverage big data for enhanced business performance. The paper identifies key areas within McDonald's operations where big data applications can be implemented. It proposes three primary big data approaches: General Content Analysis, Sentimental Analysis, and Cluster Analysis. General Content Analysis focuses on summarizing customer feedback to identify areas of improvement. Sentimental Analysis delves into customer opinions to gauge their satisfaction levels, while Cluster Analysis categorizes McDonald's outlets and regions based on content and sentimental analysis results. The proposal emphasizes the importance of customer experience and perception in the fast-food industry, suggesting these analyses will help McDonald's better understand customer needs and improve its brand image. The paper also provides background information on McDonald's, its business priorities, and challenges related to big data adoption and governance. The aim is to provide McDonald's with a data-driven approach to improve customer satisfaction and business strategies.
