Product-Service Systems 設計のためのコンテキストのモデル化手法

Abstract

Recently, value-in-context has become a key concept in enhancing the value of Product-Service Systems (PSS). The philosophy of value-in-context is that the value of products and services varies depending on the contexts where customers use the products and services. Based on this philosophy, products and services should apply to customer requirements depending on context. Context where customer uses the products and services is very often different from context assumed in design phase. Therefore, assumed value is very often not created. Creating or changing customer’s context is effective for solving this problem. To create or change customer’s context, PSS provider needs to change elements of “Ba” where customer uses products and services. However, it is difficult to make an appropriate choice of elements of “Ba” designers create or change. To support the appropriate choice, this paper proposes a framework for extracting customer’s context. The proposed method supports designers to understand relationships among value-in-context and elements of “Ba”.
