Derive: relationship between two requirements, used when a requirement is derived from another requirement.
This type of relationship is appropriate to link the requirements on different levels of abstraction. For example, a solution requirement derived from a business or a stakeholder requirement.

When validating requirements, assumptions are defined so that the associated risks can be managed.
Assumptions are considered to be true without proof for the purposes of planning and analysis, but they carry inherent risks if they prove to be incorrect. By defining assumptions clearly, business analysts and project teams can identify potential risks early in the process and develop strategies to address them, ensuring that the project remains on track and can adapt to any changes in circumstances.
References: The importance of managing risks associated with assumptions is discussed in various business analysis resources, including the Business Analysis Body of Knowledge (BABOK) and materials related to the ECBA certification provided by the International Institute of Business Analysis (IIBA). These resources emphasize the need for clear definition and management of assumptions during the requirements validation process123.

Business analysts are tasked with gathering requirements and ensuring clear communication between stakeholders and the project team. This includes identifying the most effective communication channels to facilitate elicitation activities such as interviews, workshops, surveys, and document analysis.

Traceability is a tool used in business analysis to track the life of a requirement from its origin through its development and specification, to its subsequent deployment and use, and through periods of ongoing refinement and iteration in any of these phases. It allows business analysts to determine the impact of changes in requirements by providing a clear path of how each requirement is connected to others, which is essential for assessing the consequences of changes.

When proposing design options, a number of opportunities to improve the operation of the business may occur and are compared.
Some common examples of opportunities include:
- Increase Efficiencies: automate or simplify the work people perform
