Explanation
The business analyst should focus on scheduling an all-day collaboration workshop with both teams to resolve their differences. This will allow the teams to come to a common understanding of what a qualified lead is and how they can work together to improve the lead qualification process.
Here are some additional details from Salesforce Certified Business Analyst documents and resources that support the answer:
Mapping historical lead data from each team and building charts to highlight similarities is not likely to be effective in resolving the disconnect between the teams. This is because the teams may have different definitions of what a qualified lead is, and the data may not be able to resolve these differences.
Evaluating the team's skills and experiences to determine how they can better align is not likely to be effective in resolving the disconnect between the teams. This is because the teams may have different definitions of what a qualified lead is, and the evaluation is not likely to change these definitions.
Scheduling an all-day collaboration workshop with both teams to resolve their differences is the most likely to be effective in resolving the disconnect between the teams. This is because the workshop will allow the teams to come to a common understanding of what a qualified lead is and how they can work together to improve the lead qualification process.
In conclusion, the business analyst should focus on scheduling an all-day collaboration workshop with both teams to resolve their differences. This will allow the teams to come to a common understanding of what a qualified lead is and how they can work together to improve the lead qualification process.

The best practice for identifying which stage in the sales process the industry standard due-diligence should be embedded is to develop a process map as a base, work with stakeholders to understand the trigger point, and locate the stage. This practice helps to:
Develop a process map as a base: This provides a visual representation of the sales process, showing the steps, inputs, outputs, roles, and decisions involved in each stage.
Work with stakeholders to understand the trigger point: This helps to elicit feedback and insights from the stakeholders who are familiar with or affected by the sales process, and identify when or why the industry standard due-diligence is needed or required.
Locate the stage: This helps to determine where in the sales process the industry standard due-diligence should be embedded, based on the trigger point and the business logic. References:

A cross-functional flowchart is a type of diagram that shows the steps of a business process across different roles or departments. It is useful for evaluating a business process at a high level and in detail, while also keeping regulatory considerations in mind. A cross-functional flowchart can help to identify who is responsible for each step, how information flows between different functions, and where there are gaps or inefficiencies in the process. It can also help to ensure compliance with regulations by showing how controls and checks are implemented in the process. References:
