as the Sanno-dai Shiki flowchart, the JMA flowchart, and the NOMA flowchart are major business process
modeling methods because they enable people to trace flows from the starting point to the end point with a
finger, and it is easy to share information when discussing it face to face, and they are thus suitable for a
bottom-up-style organization. By this feature, Japanese companies can realize effective bottom-up-based
business process improvement.
However, it is sometimes difficult to maintain business processes effectively because they are not usually

Japanese companies have used widely spread business flowcharts (not containing hierarchical layers) on sheets
of A0 size, for drawing up their business processes. For some Japanese companies, it is difficult to think about
top-down layered business processes, and this situation sometimes makes it difficult to develop e-business
process modeling schemes. Corresponding to this issue, the authors propose a modeling tool to support interorganizational
the interorganizational process flow adjustment described in the following chapters.
