質問 # 78
A business analyst anticipates receiving requirements changes. What should the business analyst do to avoid scope creep?
- A. Define requirements baseline and implement a change control process.
- B. Refer changes to the project manager.
- C. Meet with the stakeholder and discuss timeline impact.
- D. Implement only the original requirements.
正解：A
解説：
According to the PMI Professional in Business Analysis objectives and content, scope creep is the uncontrolled or unauthorized expansion of the project scope due to the addition or modification of requirements without proper approval or justification. Scope creep can negatively affect the project's quality, schedule, cost, and stakeholder satisfaction. To avoid scope creep, the business analyst should define a requirements baseline, which is a set of agreed-upon and approved requirements that serves as a reference for further development and testing activities. The business analyst should also implement a change control process, which is a formal and systematic procedure for managing and documenting any changes to the requirements or scope. The change control process should include steps such as identifying, analyzing, evaluating, approving, communicating, and implementing the changes, as well as updating the requirements baseline and traceability matrix accordingly.

正解：A
解説：
Explanation

The requirements baseline also serves as a reference point for managing changes and measuring progress.

質問 # 80
A company wants to procure a tool to improve customer satisfaction and loyalty. Which of the following documents would provide basis for analyzing vendor products?
- A. Project charter
- B. Storyboard
- C. Survey
- D. Business case
正解：C
解説：
Explanation
A survey is a technique to collect information, opinions, or feedback from a large number of stakeholders, such as customers or users. A survey can help to measure the current level of customer satisfaction and loyalty, and to identify the needs and expectations of the customers for the tool. A survey can provide a basis for analyzing vendor products by comparing their features, benefits, and costs with the customer requirements.
The other options are not suitable for this purpose. A storyboard is a technique to visualize the user interface or user experience of a solution using sketches or mockups. A project charter is a document that authorizes the project and defines its objectives, scope, and stakeholders. A business case is a document that provides the justification for initiating a project based on its expected benefits, costs, and risks.

質問 # 81
A project team delivers a solution based on the approved requirements and is confident that it meets the defined acceptance criteria.
What should the business analyst do to obtain signoff?
- A. Contact the sponsor.
- B. Contact the stakeholder who provided the majority of requirements in the traceability matrix.
- C. Refer to the RACI matrix to identify who is responsible for signoff.
- D. No signoff is necessary.
正解：C
解説：
A RACI matrix is a tool that defines the roles and responsibilities of stakeholders in a project or a process. It clarifies who is Responsible, Accountable, Consulted, and Informed for each task or deliverable. The business analyst should refer to the RACI matrix to identify who is responsible for signoff, as this person has the authority and accountability to approve the solution and its testing results. Contacting the sponsor, the stakeholder who provided the majority of requirements, or the project manager may not be appropriate, as they may not be the designated person for signoff according to the RACI matrix. No signoff is necessary is incorrect, as signoff is an important step to confirm that the solution meets the requirements and acceptance criteria.

質問 # 82
A business analysis team has collected the main business requirements from the major stakeholders of a project. The team wants to be sure that each stakeholder has a clear understanding of the areas of analysis that will be in scope.
Which model should the team employ to ensure the most effective representation of analysis boundary?
- A. State diagram
- B. Entity relationship diagram
- C. Data flow diagram
- D. Context diagram
正解：D
解説：
Explanation
According to the PMI Guide to Business Analysis, a context diagram is a model that shows the boundaries of an area of analysis, such as a project, a system, a process, or an organization. A context diagram depicts the main entities or actors involved in the area of analysis, and the interactions or data flows between them. A context diagram can help to ensure the most effective representation of analysis boundary, as it provides a high-level overview of the scope and context of the area of analysis, and helps to identify the key stakeholders and their relationships. A context diagram can also help to communicate and validate the scope and context with the stakeholders, and to identify any assumptions or risks related to the area of analysis. A data flow diagram, a state diagram, and an entity relationship diagram are other models that can help to analyze an area of analysis, but they do not necessarily show the boundary or scope of it. References: PMI Guide to Business Analysis, page 158-159.

質問 # 88
The requirements traceability matrix should primarily be used to:
- A. identify the risks associated with dependent requirements.
- B. define a convention to map the requirements to their sources.
- C. ensure that all requirements have been met.
- D. address the responsibility owner for each requirement.
正解：C
解説：
Explanation
A requirements traceability matrix (RTM) is a tool that helps to track the relationship between the requirements and the product features, test cases, and other artifacts. It can be used to ensure that all requirements have been met by verifying that each requirement has a corresponding feature, test case, and acceptance criterion. A RTM can also help to identify the risks associated with dependent requirements, but that is not its primary purpose. A RTM does not define a convention to map the requirements to their sources, but rather uses an existing convention or standard. A RTM does not address the responsibility owner for each requirement, but rather shows the status and priority of each requirement. References: PMI Professional in Business Analysis (PMI-PBA)

- A. A configuration verification and audit system
- B. A change control board
- C. A configuration management system
- D. A requirements traceability matrix
正解：C
解説：
Explanation
A configuration management system is a standardized, effective, and efficient way to manage changes to project documentation. A configuration management system is a set of tools and processes that help to track, control, and update the configuration items (CIs) of a project, such as documents, requirements, designs, code, tests, etc. A configuration management system helps to ensure that the project documentation is consistent, accurate, and up-to-date throughout the project life cycle. It also helps to maintain the traceability and auditability of the changes made to the project documentation. A configuration management system typically includes the following components:
A configuration management plan that defines the scope, roles, responsibilities, policies, procedures, and standards for configuration management.
A configuration management database (CMDB) that stores the information about the CIs, their attributes, relationships, versions, baselines, and changes.
A configuration identification process that assigns unique identifiers and names to the CIs and their versions.
A configuration control process that evaluates, approves, and implements changes to the CIs and their versions.
A configuration status accounting process that records and reports the status and history of the CIs and their versions.
A configuration verification and audit process that verifies and validates the CIs and their versions against the requirements and specifications.
