Abstract

Indonesian micro, small, and medium enterprises (MSMEs) are moving into digital commerce, but the move remains scattered. National statistics show that 94.76% of e-commerce businesses sell through instant-messaging applications and only 17.23% through a marketplace platform, while 48.03% still arrange delivery themselves and cash remains the dominant settlement method. Multi-sided marketplace platforms can consolidate this activity, but designing them is architecturally demanding. Existing enterprise architecture (EA) studies also seldom verify whether every fundamental descriptive dimension of the enterprise has been addressed. This study proposes a completeness-driven EA for a multi-sided e-commerce marketplace. It integrates the TOGAF Architecture Development Method (ADM) as the design process, ArchiMate 3 as the modeling language, and the Zachman Framework’s 5W1H ontology (What, How, Where, Who, When, Why) as an explicit completeness lens. Within a Design Science Research approach, the artifact is developed across TOGAF ADM Phases A to D and evaluated through architectural consistency checking, gap analysis, and a structured completeness assessment that maps every model element onto a perspective-by-aspect matrix under a stated population rule. Of the 24 cells assessed, 20 are fully populated, 3 are only partially populated, and 1 is weak. The What, How, Where, Who, and Why aspects are answered at all four perspectives, while the temporal When aspect accounts for every cell that falls short. The study contributes a reusable blueprint for marketplaces that advance SME digitalization, an escrow mechanism modeled end-to-end including its dispute path and regulatory driver, and a replicable procedure for assessing architectural completeness.
