問 6
- ア
正解 A workflow system is a system that defines on a computer the flow of a company’s routine administrative procedures itself — drafting an application form → confirmation by a superior → ringi (circular) approval and authorization → filing — and automatically routes the document (as electronic data) to the next person in charge. Choice ア, “When purchasing equipment, conduct the entire sequence of steps over the network, from drafting the application documents through to ringi (circular) approval,” is exactly an example of digitizing the approval process of “who → passes it to whom → in what order,” and is a typical use of a workflow system. Because nobody has to carry a paper ringi document around from desk to desk, you gain benefits such as a shorter time to final approval, visibility of progress (where the document is currently held up), and a record of the approval history. Therefore the correct answer is ア.
Incorrectイ
Linking information on material procurement, production, sales, and logistics in an integrated way to cut wasteful inventory describes SCM (supply chain management). It is a mechanism for optimizing the whole “flow of goods and information” across companies and departments, so both its purpose and its target differ from a workflow system, which routes in-house application and approval procedures.
Incorrectウ
Exchanging commercial transaction data such as quotations and purchase orders between your company and its customers over a network describes EDI (Electronic Data Interchange). EDI is a mechanism that standardizes the format and procedures of transaction data exchanged between companies; it is not a workflow system that defines an in-house approval route and routes documents along it.
Incorrectエ
Procuring just the necessary parts in just the necessary quantity from the preceding process in line with the production status of one’s own process describes the just-in-time method (kanban system). It is a production-management approach that holds no work-in-process inventory, and it has nothing to do with a workflow system, which routes administrative procedures electronically.
ここがポイント
- Workflow system = a mechanism that digitizes the flow of routine in-house administrative procedures such as application, review, and final approval, and automatically routes documents to the people involved. Its main benefits are faster approval and visible progress.
- Telling confusable terms apart: SCM = optimizing the entire supply chain from procurement through logistics; EDI = electronic exchange of commercial transaction data between companies; just-in-time (kanban system) = a production method that procures only what is needed, when it is needed, in the quantity needed.
