The alignment between the business strategy of an organization and its related information technology (IT) strategy, infrastructure and processes remains important for both research and practice. Prior studies have shown that effective strategic IT alignment (SITA) leads to effective business value. When measuring the SITA, these studies focused on the overall information system (IS) of an organization. However, it would be useful for practitioners to evaluate, not only a global alignment, but also the alignment of a specific business software application, which could lead to business value as well. Previous investigations in the IS evaluation field, such as studies related to the Information Systems Success Model (ISSM), do not include strategic alignment factors. In this contribution, we address the issue of how to evaluate a business software application using SITA factors. To identify SITA factors, we selected a set of scientific papers and documents from practitioners related to strategic alignment and we used them as input for a coding process. We followed the thematic analysis method for coding and we obtained a hierarchical structure of SITA factors. From this structure, and based on the Strategic Alignment Model (SAM), we built an emergent alignment model that clarifies relations between a business software application and first the organization’s strategies (business and IT), second the organizational structure, and third the processes and operations of the IT department. The model reveals that all relations, except those between business strategy, organizational structure and business operations, are appropriate for evaluating the strategic alignment of a business software application.
