Organizational change has been a key component in enhancing performance and
organizational design. Previous process-oriented organizational change met
hods, however, focused on simplifying process flow without examining how it
affects other organizational elements. Since an organization consists of s
everal interdependent elements, a change within an organization can affect
the other dependent organizational elements. Lack of coordination within an
organization can result in unexpected poor performance and high coordinati
on cost. In this research, we suggest a coordination theory approach to org
anizational process change by applying the Massachusetts Institute of Techn
ology Process Handbook with simulation technique. For the validity test, we
applied the Process Handbook to a real hospital. From the application case
, we saw that the proposed approach is useful in minimizing the risk of the
change project by validating change alternatives using simulation techniqu
e, coordinating the dependent organizational elements, and managing change
effects on other organizational elements. In this article, we discuss the p
roposed method and the transformation of a new organizational design to the
workflow system development.
