Abstract— PT.XYZ is a gas oil manufacturing company,
which produces offshore oil and gas drilling equipment. In
supporting its business processes, this company uses a separate
module application which causes data flow to be interrupted and
results in the company experiencing delays in managing data and
getting information on time. Based on the analysis of the
problem, the researcher will design an integrated enterprise
information system architecture for sales, finance, raw material
procurement, production, project plan, and inventory. The
method used is the TOGAF ADM 9.2 framework which consists
of four phases, namely the vision architecture, business
architecture, information system architecture, and technology
architecture phases. This enterprise architecture design produces
a blueprint as a guideline or framework in the development of
information systems at PT. XYZ. The overall result of this
research is to produce an enterprise architecture information
system design.
