Explanation
The best practice to establish benchmarks to evaluate existing processes is to show tangible impact from changes to processes. Benchmarks are quantifiable measures that can be used to compare current performance with desired performance or best practices. They can help CK evaluate how effective its sales processes are, identify gaps or opportunities for improvement, and measure the results or benefits of process changes.
Proving processes are out of date and require a new solution is not a best practice, but a potential outcome of benchmarking. Comparing processes against CK's closest competitors is not a best practice, but a possible source of benchmarking data. References:

This answer states that scheduling a one-on-one meeting with the new employee to get an alternative perspective from a beginner's mind is what the BA should do when responding to the new employee's input.
A beginner's mind is a mindset that is open, curious, and eager to learn, without any preconceptions or biases.
A beginner's mind can help the BA to discover new insights, ideas, or opportunities that might otherwise be overlooked or dismissed by more experienced or knowledgeable stakeholders. Scheduling a one-on-one meeting with the new employee can help the BA to listen to their input, understand their perspective, and appreciate their contribution.

The information that the business analyst should gather during the initial discovery meeting is the limitations of the current support process. The initial discovery meeting is a meeting where the business analyst meets with the key stakeholders and sponsors of a project to understand their needs, expectations, goals, challenges, and pain points. The business analyst should gather information about the limitations of the current support process to identify the gaps, issues, or opportunities for improvement that the project aims to address. The business analyst should also gather information about the scope, budget, timeline, deliverables, roles and responsibilities, and success criteria for the project. The employee review cycle for the support team is not information that the business analyst should gather during the initial discovery meeting. The employee review cycle is a process that evaluates the performance and development of employees on a regular basis. It is not relevant to the project scope or objectives and does not help identify the limitations of the current support process. The contact information for key stakeholders is not information that the business analyst should gather during the initial discovery meeting. The contact information for key stakeholders is a detail that can be obtained before or after the meeting, but it does not help understand the needs or expectations of the stakeholders or the limitations of the current support process.

The group that the business analyst should include early in the scoping process is stakeholders. Stakeholders are individuals or groups who have an interest or influence in the project outcome, such as customers, users, sponsors, managers, team members, etc. Stakeholders should be involved early in the scoping process because they can help to define the project vision, goals, objectives, requirements, expectations, and success criteria.
Stakeholders can also help to identify any risks, issues, assumptions, or constraints that may affect the project scope. Involving stakeholders early in the scoping process can help to ensure alignment, engagement, and satisfaction with the project outcome. References:
