This chapter presents a case study of digital transformation for supplier selection at a leading Vietnamese restaurant chain through a pragmatic constructivist perspective focusing on four dimensions: facts, possibilities, values, and communication. This perspective provides a theoretical framework for analyzing the success of digital transformation for supplier selection. The findings show that the restaurant chain faced challenges in operational efficiency (e.g., resource allocation) and control issues, which were derived from manual processes, personal relationship-based decisions, system shortages, and inconsistent evaluation criteria. The possibilities offer the restaurant chain solutions to overcome these challenges with employment of various technological infrastructure, including E-ticket, E-process for task management, E-bidding for supplier sourcing, the Delivery in Full on Time (Difot) for evaluating supplier performance, and SAP integration to manage supplier data. These digital elements enable the restaurant chain to standardize its supplier selection process and improve its monitoring procedures. The underlying value for this transformation is fair competition among suppliers, leading to better operational outcomes. Digital transformation enhances objectivity and transparency of the supplier selection process, resulting in higher operational efficiency and supplier quality. These three dimensions are realized through communication with two key factors: coordination across the restaurant chain's departments for reconciliation of diverse objectives and knowledge sharing through internal staff development and supplier engagement programs. This case study provides rich descriptions of digital transformation for supplier selection in the context of the restaurant chain through the lens of pragmatic constructivism.
