What document should a business analyst update for approved changes during an implementation project?

The most appropriate document for a business analyst to update for approved changes during an implementation project is a combination of both the traceability matrix and the process definition document.

The traceability matrix is critical because it links requirements to their corresponding implementation elements, ensuring that all aspects of the project are aligned with the initial specifications. When a change is approved, it is essential to update this matrix to reflect how those changes impact existing requirements, user stories, test cases, and other project components.

The process definition document outlines the current processes and workflows within the project. Any approved changes could involve modifications to existing processes or the introduction of new workflows. Updating this document ensures that all stakeholders have a shared understanding of how processes will function after the changes are implemented.

Updating both documents is vital for maintaining comprehensive and accurate project documentation, which aids in communication among stakeholders and supports effective project management. This approach ensures that all changes are properly tracked, enabling a smoother implementation and reducing the risk of miscommunication or errors later in the project. Other choices may address only one aspect, but the combination recognizes the interconnectedness of requirements and process documentation, making it the most thorough and effective approach.
