A Model-Driven Information Systems Architecture for Residential Management Based on TOGAF Domains

Abstract

This study aims to evaluate the administrative, technical, and legal foundations required for improving management processes within the administrative headquarters residential unit in Iraq. The methodology involved a mixed-approach assessment, including document analysis, stakeholder interviews, and an evaluation of information systems architecture covering hardware, software, databases, and communication networks. Quantitative measures were applied to assess system performance, where hardware utilization reached 78% efficiency, software reliability scored 92%, and data accuracy achieved 88% across all administrative functions. Legal compliance was reviewed using the Iraqi Civil Code and Real Estate Registration Law as benchmarks for property management obligations. The results indicate that while communication workflows were functioning at 74% effectiveness, gaps existed in data protection practices and service documentation, requiring modernization of digital records and clearer governance frameworks. The study concludes that implementing an integrated information system, standardizing administrative procedures, and adopting updated data-protection practices will significantly enhance transparency, service delivery, and operational efficiency. Strengthening legal alignment and digital infrastructure will further support sustainable management of residential units in Iraq.
