What Method is to Achieve the Purposes of Systems-of-Systems Having Different Boundaries as System-of-Systems for Each Organization?

Abstract

In an enterprise, designing system-of-systems (SoS) is required to assume and clarify each organizationspecific viewpoint for the SoS, in order to solve problems within their budgets and benefit. The previous study suggests that designing the IT system as to achieve different purposes depending on the various positions is difficult. To solve the above problems includes two difficulties which must solve at least. One difficulty is that if the organizations do not have enough conversation among organizations, the organizations cannot reduce the range of what we do now know the ‘unknown unknowns'. Another difficulty is that to achieve two (or more) purposes at the same time. Therefore, the purpose of this study is to reduce misunderstanding at the time of SoS design in different positions that have each different purpose, in order simultaneously to achieve the purposes of SoSs which have different boundaries defining as SoS for each organization. We will propose a design method which assumes the purpose of this study, includes steps to make it that can commonize design by two positions. To evaluate the proposed method, we actually applied the proposed method to the processes for the order for sales and the maintenance for the product in the manufacturing industry.
