IPA IP 2026 Question 12
A question IPA Japan published in 令和8年度 ITパスポート試験 公開問題 問12, translated into English. ITPEC is based on the same exams.
Company A decided to visualize its business processes by using a flow diagram in order to identify issues in its own business processes and review them. Which of the following is the most appropriate notation that Company A uses in creating the flow diagram?
Explanation
WFA (Work Flow Architecture) — a notation built for drawing the flow of business operations.
WFA draws a business process as a flow diagram: the departments or roles in lanes, the tasks as boxes, and arrows for the order of the work and for the documents and data passed between tasks. Seeing who does what, in what order, shows where work waits, repeats or is handed over needlessly, so it suits finding issues and reviewing a process. BPMN and swimlane activity diagrams are other notations for the same purpose.
Answer (d)
Why not others:
- •(a) — a CRUD diagram is a matrix of which process creates, reads, updates or deletes which data; it shows data use, not the flow of work
- •(b) — DMM (Diamond Mandala Matrix) is a matrix technique for organising and analysing ideas and relationships, not a flow diagram
- •(c) — an E-R diagram models data as entities and the relationships between them, with no order of tasks
Key rule: To model the flow of business operations use a flow notation (WFA, BPMN, activity diagrams); CRUD diagrams and E-R diagrams describe data, not process.
