Explanation
The following considerations should be considered regarding the data model for the broker web portal:
The Broker Assistant should be modeled as a Contact. Then, leverage Contact to Multiple Account features if this assistant needs to work for multiple brokers. This is because Contacts are records that represent individuals who are associated with an account. By using Contacts, the consultant can capture the personal information of the broker assistants and relate them to their employers. By using Contact to Multiple Accounts features, the consultant can enable a contact to have relationships with multiple accounts and specify different roles and start and end dates for each relationship.
Brokers need to be modeled as Account and Contact individually, as each broker is a legal entity in Salesforce. Then, use a Group to model their company. This is because Accounts are records that represent business entities or organizations that are involved in business transactions with your company. By using Accounts, the consultant can capture the business information of each broker and treat them as legal entities in Salesforce. By using Contacts, the consultant can capture the personal information of each broker and relate them to their accounts. By using Groups, which are records that represent collections of accounts or contacts that share financial goals or characteristics, the consultant can model the broker company and associate multiple brokers with it

Action Plans are a feature that allows users to create templates for common client processes, such as loan approval, account opening, or financial review. Action Plans can create repeatable tasks and automate the task sequences when executed. When an action plan is created from a template for a specific target record, such as an account or an opportunity, items that have no assigned user are assigned to the owner of that target record. Action Plans can also enhance collaboration and productivity by automatically assigning task owners and deadlines for specific client processes.

Explanation
Discovery Framework is a scalable assessment framework that financial institutions use to gather and evaluate customer information through digital and human channels. Some of the things to consider regarding Discovery Framework are:
Discovery Framework creates highly capable forms with integrations and advanced logic. The forms can be customized with various types of questions, validations, calculations, branching, and integrations with external systems1.
Discovery Framework can create both standard and hierarchical questions. Standard questions are single-level questions that can be grouped into sections. Hierarchical questions are multi-level questions that can have subquestions based on the answer to the parent question2.
FSC Discovery Framework allows archiving questions. Archiving a question removes it from the active question pool and prevents it from being added to new forms. Archived questions can be restored if needed3.
