Figure 13
The diagram illustrates two different interaction models between Actor A and Actor B. First Model (on the left): Actor A is represented in a box with three roles or responsibilities, labeled C, A, and R, indicating the different responsibilities within the interaction. Actor A initiates an action with a Transaction (T) that moves to Actor B, who completes the transaction. The diamond shape representing T indicates the exchange or process that occurs between the two actors. Second Model (on the right): This model features Actor A sending a transaction to Actor B, but the transaction is conditional or incomplete. The dotted arrow from Actor B suggests that the transaction is not fully executed or finalized, and Actor B may be in a decision-making or pending state.Examples of construction flaws (ECFs) experienced by the panel of experts
