According to the IIBA, a data flow diagram is a technique that shows where data comes from, which activities process the data, and if the output results are stored or utilized by another activity or external entity1. A data flow diagram consists of four basic elements2:

Data flow: A data flow is a line that represents the movement of data from one point to another. It can be labeled with the name or description of the data.

External entities: External entities are rectangles that represent the sources or destinations of data outside the system boundary. They can be people, organizations, systems, or devices that interact with the system.

Data process: A data process is a circle that represents a process that transforms data by performing some operation on it. It can be labeled with the name or description of the process.

Data store: A data store is an open-ended rectangle that represents a place where data is stored or retrieved. It can be a database, a file, a queue, or a memory.

Among these elements, the one that represents a process that transforms data by combining it with other data is concatenation. Concatenation is a type of data process that joins two or more data flows into one data flow. For example, a concatenation process can combine the first name and last name data flows into a full name data flow3. References:

Linked is not a valid relationship type among requirements. Requirements can have different types of relationships, such as derivation, satisfaction, verification, refinement, traceability, dependency, conflict, or overlap1. These relationships can help to analyze the impact, consistency, completeness, and quality of the requirements2. However, linked is not a specific or meaningful term to describe how requirements are related.

The other options are valid relationship types among requirements:

Necessity is a relationship type that indicates that a requirement is essential for achieving a goal or satisfying a need3.

Cover is a relationship type that indicates that a requirement addresses or fulfills a stakeholder need or expectation4.

Subset is a relationship type that indicates that a requirement is a more detailed or specific version of another requirement5.

 The scenario describes a task that involves creating a business process model (BPM) for the error-handling process on the website. The BPM is a technique used by business analysts to visualize and document the activities, flows, and roles involved in a business process. The BA has two sources of information for this task: the workshop results and the instruction manual. The BA should use both sources to create the BPM, but also identify and resolve any discrepancies in process between them with the stakeholders. This would ensure that the BPM is accurate, consistent, and aligned with the stakeholder needs and expectations.
