Explanation
This answer states that using who, what, and why is what each user story should include for optimizing a very manual process in its Salesforce org. Who refers to the persona, which is a fictional representation of a typical user or stakeholder who will use or benefit from a feature or a functionality. What refers to the goal, which is what the user or stakeholder wants to accomplish with the feature or functionality. Why refers to the value, which is why the user or stakeholder wants to accomplish the goal, and how they will measure success. Using who, what, and why can help the BA to write effective user stories that capture and prioritize the requirements, and align them with the stakeholder value and expectations.

The tool that would help UC understand the existing functionality of all of its reporting tools is a capability model. A capability model is a visual representation of the core capabilities or functions that an organization performs or delivers to achieve its strategic objectives. A capability model helps to identify and organize high- level process areas that span across different departments or teams, as well as highlight any gaps or overlaps in functionality. A capability model can also help to prioritize and scope Salesforce projects based on business value and impact.
In this case, UC can use a capability model to map out all of its reporting tools by their capabilities or functions, such as data sources, data integration, data analysis, data visualization, data sharing, etc. This would help UC understand what each reporting tool can do or provide, how they relate or differ from each other, and where there may be redundancies or inefficiencies in their reporting processes.

Explanation
Annotated process flows are a great way to illustrate the vision of a solution to stakeholders. They can show the current state of the process, the proposed changes, and the benefits of the changes. This can help stakeholders understand the solution and why it is needed.
Here are some additional details from Salesforce Certified Business Analyst documents and resources that support the answer:
Annotated process flows are process flows that include additional information, such as notes, comments, and explanations.
Modifications to an existing process are changes that are made to an existing process.
Stakeholders are people who have an interest in the success of a project.
In conclusion, annotated process flows with modifications to an existing process are a great way to illustrate the vision of a solution to stakeholders. They can show the current state of the process, the proposed changes, and the benefits of the changes. This can help stakeholders understand the solution and why it is needed.
An artifact that can help the business analyst illustrate the vision of a solution to stakeholders is annotated process flows with modifications to an existing process. Annotated process flows are diagrams that show how a process works step by step, with notes or comments that explain the logic or rationale behind each step. They can help the business analyst show how the lead routing and qualification process will change or improve with the new solution, and invite feedback or validation from stakeholders. Detailed user stories with technical documentation about the existing process are artifacts that can help the business analyst capture the requirements or specifications of the new solution, but not illustrate the vision of it. Collected pain points from people who follow the existing process are artifacts that can help the business analyst understand the problems or needs of the end users, but not illustrate the vision of the solution.
