Abstract — As time goes by the needs and aspects of
competence and productivity of Human Resources (HR) are
increasingly diverse to form complex communication patterns. To
balance and fulfill those needs and aspects, there needs to be an
increase in performance, one of them is with enterprise architecture
(EA). This study raises the case of one manufacturing company
with a focus on the HR management function which has problems
regarding the composition and competency of HR that is uneven so
that HR productivity is low. One solution to this problem is by
designing an EA. The solution produced in this research is
expected to be able to meet the company's business requirements
which will then be able to help meet the goals of the HR
management function and also the company by considering aspects
of HR. The design method of this research EA uses TOGAF ADM
(The Open Group Architecture Framework) which is one of the
frameworks for designing EA by connecting business architecture,
data, applications, and technology. TOGAF ADM is flexible so it is
possible to proceed with a different framework. In this research, EA
design focuses on only three stages, namely the preliminary phase,
architecture vision, and business architecture. Business
architecture is a phase in the TOGAF ADM which acts as the main
component capable of sustaining further architecture. The business
architecture contains the definition of baseline architecture and
targeting which will be used as guidelines for the basis for the
development of integrated information systems for the HR
Management Function. Business architecture is very instrumental
in helping to handle the issues and risks that occur in the company,
so it can facilitate the company to make the right decision.
