A process map is a visual representation of a business process that helps to engage stakeholders, identify improvements, and start the change process. By creating a process map, the business analyst can understand the current state of the process, identify pain points and opportunities for improvement, and communicate the findings and recommendations to the stakeholders. A process map also helps to initiate the change process by providing a baseline for measuring the impact of the proposed solutions. References:

Email Proof is the User access and sharing feature that would be used for the following use case: it is the first time a user logs in and they need to be sent an email with a way to authenticate their email. Email Proof is a security feature that requires users to verify their email address when they log in for the first time or change their email address. 2 FA, Single Sign-On, and Login Link are not User access and sharing features that would be used for this use case.

Explanation
The initial steps that the business analyst should take to help determine why the order management and fulfillment process is slow are:
Work with stakeholders to identify relevant processes, such as order placement, order confirmation, order processing, order shipping, order tracking, etc.
Select a key process with defined start and end points, such as order processing, which involves verifying customer information, checking inventory availability, allocating products, generating invoices, etc.
Collaborate with process owners and users to create a current state process map, which shows how the order processing process is currently performed in Salesforce, what steps or activities are involved, what inputs or outputs are used or produced, what decisions are made, what roles or systems are interacted with, etc.
These steps help to establish a baseline for measuring the current state of performance, identify pain points and opportunities for improvement, and align with the desired business outcomes. References:
