 A use case diagram is a technique that helps to depict the interactions between a system and its actors using graphical symbols and relationships. A use case diagram shows the actors that are involved in the system, the use cases that represent the functions or services that the system provides, and the associations that indicate how the actors and use cases are related. A use case diagram can be used with a state diagram to verify that all functions are defined to work with entity “User” for the different roles, as it can help to identify the use cases that correspond to the states and transitions of the entity, and to ensure that the use cases are complete, consistent, and accurate. A sequence diagram is a technique that helps to represent the sequence and timing of the messages that are exchanged between the objects or components of a system. A sequence diagram shows the objects or components that participate in the interaction, the messages that are sent and received by the objects or components, and the time order of the messages. A sequence diagram can help to illustrate the dynamic behavior and logic of the system, but it does not show the interactions between the system and its actors. A functional diagram is a technique that helps to represent the functions or processes that are performed by a system or a solution using graphical symbols and relationships. A functional diagram shows the functions or processes that are relevant to the domain, the inputs and outputs of each function or process, and the decomposition and hierarchy of the functions or processes. A functional diagram can help to define and analyze the functional requirements, but it does not show the interactions between the system and its actors. A data flow diagram is a technique that helps to create a high-level overview of a business process by showing the movement and transformation of data between entities and processes. A data flow diagram uses graphical symbols and arrows to represent the sources and destinations of data, the processes that manipulate data, the data stores that store data, and the data flows that transfer data. A data flow diagram can help to understand and document the data logic and structure of the business process, but it does not show the interactions between the system and its actors. References: BABOK Guide v3, Chapter 10: Techniques, Section 10.50: Use Case Diagram, p. 564-566; Section 10.49: Sequence Diagram, p. 562-563; Section 10.22: Functional Decomposition, p. 528-529; Section 10.18: Data Flow Diagrams, p. 522-524.

 A purchase solution approach is one that involves acquiring a COTS software package from an external vendor or provider, rather than developing a custom solution in-house. A purchase solution approach can offer several benefits, such as faster delivery, lower cost, higher quality, and reduced risk. However, a purchase solution approach also has some drawbacks, such as limited customization, dependency on the vendor, compatibility issues, and licensing fees. A BA should evaluate the pros and cons of a purchase solution approach against the business needs and requirements, and compare it with other possible solution approaches, such as outsource, exploit, or create. References:

 A risk-averse organization is one that prefers to minimize or eliminate the exposure to risks, even if it means sacrificing some potential benefits or opportunities. A risk avoidance strategy is one that involves changing the project plan, scope, schedule, or budget to avoid the risk or its impact. A risk avoidance strategy is suitable for a risk-averse organization, as it reduces the uncertainty and the potential negative consequences of the risk. In this scenario, the BA has identified an assumption that has a high degree of uncertainty and may affect the validity of the requirements. The BA has added the assumption to the risk register and performed a risk analysis to handle this situation. If the organization is risk-averse, the BA may use a risk avoidance strategy to modify the requirements or the solution design to eliminate the dependency on the assumption, or to seek more information or evidence to validate the assumption. A risk acceptance strategy is one that involves acknowledging the risk and its impact, but not taking any action to prevent or reduce it. A risk acceptance strategy is suitable for a risk-seeking or risk-neutral organization, or for risks that have low probability or impact. A risk transfer strategy is one that involves shifting the responsibility or ownership of the risk or its impact to a third party, such as a vendor, a partner, or an insurer. A risk transfer strategy is suitable for risks that have high impact but low probability, or for risks that require specialized skills or resources to manage. A risk mitigation strategy is one that involves taking actions to reduce the probability or impact of the risk, such as implementing contingency plans, preventive measures, or backup solutions. A risk mitigation strategy is suitable for risks that have high probability and impact, or for risks that can be controlled or influenced by the project team. References: BABOK Guide v3, Chapter 10: Techniques, Section 10.51: Risk Analysis and Management, p. 567-569; Free CBAP IIBA Actual Exam Questions & Answers, Question 467.

 A business analysis checklist is a technique that helps to ensure that all the required business analysis activities and deliverables are completed and verified. A business analysis checklist can include items such as the scope statement, the stakeholder list, the requirements documentation, the traceability matrix, the validation criteria, the change requests, and the approval signatures. A business analysis checklist can help to mitigate the concern of the project board by providing a clear and comprehensive overview of the business analysis work and its quality. A data model is a technique that helps to represent the data and information needs of an organization or a solution using graphical or textual symbols and relationships. A data model can help to define and analyze the data requirements, but it does not ensure that all the requirements are verified. A use case diagram is a technique that helps to depict the interactions between a system and its actors using graphical symbols and relationships. A use case diagram can help to define and analyze the functional requirements, but it does not ensure that all the requirements are verified. A risk register is a technique that helps to identify, analyze, and manage the uncertainties and threats that may affect the project or the solution. A risk register can help to mitigate the potential impacts of the risks, but it does not ensure that all the requirements are verified. References: BABOK Guide v3, Chapter 10: Techniques, Section 10.8: Business Analysis Checklist, p. 504-505; Section 10.18: Data Modelling, p. 522-524; Section 10.50: Use Case Diagram, p. 564-566; Section 10.51: Risk Analysis and Management, p. 567-569.
