CASE ANALYSIS

Scenario

Modeling the online banking transaction process at a high level using IDEF0 methodology.

Key decisions

  • Used signal nodes to represent IDEF0 arrows
  • Edge labels differentiate ICOM types (input, control, output, mechanism)
  • Single function block A0 encapsulates the core transaction process

When to reuse this

Applicable when a high-level functional decomposition is needed, often for business process or system analysis using IDEF0.
