This document summarizes a case study on the sustainability of Indonesia's national eProcurement system. Key findings include:
1) Sustainability was determined by technical, legal, and managerial factors that were interlinked in a "triple-helix" model.
2) Regulations, training, and technical standards ensured the system was learned, standardized, and integrated into procurement practices.
3) A permanent in-house IT team and incremental development helped maintain the system's alignment with user needs over time.
