This article examines a key legal issue related to the integration of system analysis, information management, and decision-making, focusing on data privacy. The study employs a literature review, comparative analysis, and policy analysis to investigate the current legal frameworks, approaches taken in different jurisdictions, and potential solutions. Our findings reveal that inconsistencies in data privacy regulations and challenges in compliance significantly impact stakeholders in these fields. We propose several potential solutions, including the harmonization of data privacy laws, the adoption of privacy-enhancing technologies, and the implementation of education and training programs. Policymakers and stakeholders should adopt a proactive approach and foster international cooperation to create an environment that enables innovation while safeguarding individual privacy rights. This article contributes to the understanding of the legal challenges and implications in the rapidly evolving fields of system analysis, information management, and decision-making.
