Customizing information systems is a pivotal process that tailors ICT (Information and Communication Technology) systems to the unique needs and interests of businesses. These systems proactively scan resources, analyze data, and present information to meet user needs. Customization is the process of adapting software, hardware, or IT components to align with a business's specific requirements. This enables organizations to optimize their IT infrastructure, streamline workflows, and support specific processes. The phases of customization involve identifying business goals, configuring software, developing bespoke solutions, enhancing the user interface, data integration, workflow automation, and creating custom reporting and analytics tools. Thorough testing, quality assurance, documentation, training, and regular maintenance ensure that customized information systems fulfill requirements and adapt to evolving business needs
