The business analyst should find a middle ground where both stakeholders are satisfied with the field names, as this would ensure that the requirements are accurately captured and reflect the needs of the business. The business analyst should facilitate a discussion between the stakeholders to understand their perspectives and preferences, and help them reach a consensus on the field names. This would also foster collaboration and trust among the stakeholders, and avoid potential conflicts or confusion later in the project. References:

Explanation
A possible reason why the test cases failed is missing test script details. Test scripts are step-by-step instructions on how to execute each test case. They should include the expected inputs, outputs, and results for each step. Missing test script details could lead to confusion, errors, or inconsistencies among testers, resulting in failed test cases. Missing test org access details is not a likely reason why the test cases failed because it would prevent testers from accessing the sandbox or test environment, not from executing the test cases.
Missing test result details is not a likely reason why the test cases failed because it would affect the reporting or documentation of testing outcomes, not the execution of test cases. References: 1

This answer explains that an activity box marked "C Customer" means that the customer should be consulted.
In a process map that uses Universal Process Notation (UPN), an activity box is a symbol that represents a task or an action that is performed in a business process. An activity box can be marked with a letter to indicate the role or the resource that is responsible for performing the task or action. The letter C stands for consult, which means that the resource should be asked for input or advice before or during the task or action. References:
