The visualization depicts a business process model (BPMN) diagram for a credit scoring system. It illustrates the interactions between three participants: a frontend bank, a credit scoring bank, and a scoring service. The process outlines how a credit score request is handled and the different paths it can take depending on score availability and processing time.

Here's a breakdown of the process:

**1. Frontend Bank (Topmost pool):**

* Starts with a blank start event.
* Receives a scoring request.
* **Request Credit Score:** Sends the request to the credit scoring bank.
* Can receive either a 'delay information' or a 'credit score' from the scoring bank.
* If delay information is received:
    * **Report Delay:**  Notifies the customer about the delay.
    * Waits to receive the 'credit score'.
* Once the 'credit score' is received:
    * **Send Credit Score:**  Forwards the score to the customer.
* Ends with a terminate end event, marking the 'scoring request handled'.

**2. Credit Scoring Bank (Middle pool):**

* Receives the 'scoring request' from the frontend bank.
* Forwards the request to the scoring service.
* Receives the 'credit score' from the scoring service.
* Sends either 'delay information' or 'credit score' to the frontend bank, depending on the response from the scoring service.

**3. Scoring Service (Bottom pool):**

* Receives the 'scoring request' from the credit scoring bank.
* **Compute Credit Score (Level 1):** Performs an initial credit score calculation.
* **Score Available?**: Checks if a sufficient score can be calculated immediately.
    * **Yes:** 
        * **Send Credit Score:** Sends the calculated score to the credit scoring bank.
    * **No:**
        * **Report Delay:** Informs the credit scoring bank about the delay.
        * **Compute Credit Score (Level 2):** Performs a more comprehensive credit score calculation (possibly involving external data sources, indicated by the note "inkl. ID for message queuing").
        * **Send Credit Score:** Sends the final score to the credit scoring bank.
* Ends with a terminate end event, indicating the 'scoring request handled'.

**Key elements and notations in the diagram:**

* **Pools:**  Represent the different participants (frontend bank, credit scoring bank, scoring service).
* **Lanes:** (Not explicitly shown, but implied by the pools) Represent different departments or roles within a participant.
* **Events:**  Circles representing the start and end of a process or subprocess.
* **Activities:** Rectangles representing tasks performed within the process.
* **Gateways:** Diamonds representing decision points or parallel paths.
* **Message Flows:** Dashed arrows depicting the exchange of information between participants.
* **Sequence Flows:** Solid arrows showing the order of activities within a process.

This BPMN diagram effectively visualizes the flow of information and tasks involved in processing a credit score request, including handling potential delays and different levels of credit score computation.
