Objective: The purpose of this study is to propose a method for assessing the state of information technology (IT) deployment in libraries. This is achieved by developing a sample organizational architecture model based on the TOGAF framework. By leveraging the findings of this assessment, libraries can improve alignment between IT and business processes. As a result, system effectiveness can increase while operational costs decrease. To illustrate the applicability of the proposed approach, the library of Astane Qods Razavi is selected as a case study.

Methodology: This research is applied in nature and follows a case study approach. The method is implemented using TOGAF (Version 10) and the ArchiMate modeling language. First, the required data are collected through the review of library documents and related reference materials. Then, the gathered information is documented using standard TOGAF artifacts, including catalogs and matrices. Next, multiple architectural views are created using ArchiMate to support the visualization of the resulting organizational architecture implementation. Finally, the proposed model is evaluated using key performance indicators and verified according to its capability to support TOGAF’s Architecture Development Method (ADM) .

Findings: After implementing the “current state” phase of organizational architecture in the selected library, the study identified and categorized the library’s main business processes. In addition, the research documented and mapped the various IT tools used by the library, along with the nature of their relationships to library services. Using ArchiMate, multiple architectural views and representations were designed to produce a precise visual depiction of the organizational architecture documentation and its links to IT-supported services and process execution. Overall, the developed artifacts clearly show how IT is utilized to support operational workflows and service delivery within the organization.

Conclusion: The combined use of TOGAF and ArchiMate provides a structured and systematic toolset for analyzing, documenting, and designing information architecture in libraries. The proposed model can serve as a practical guide for other libraries and information centers that aim to establish organizational architecture. Such an approach enables a more transparent understanding of the current status of IT deployment and supports more informed decision-making for architectural improvement.

In turn, this facilitates system integratio, improves service quality ,and strengthens the alignment of IT capabilities with organizational missions. Ultimately, the adoption of the proposed method can lead to higher productivity, greater process transparency, reduced duplication of efforts, and improved overall service quality for stakeholders.
