Which type of field cannot be universally required?

Universal Containers has two types of applicants, hourly and salary. There are separate record types for each. While all members of the human resource department need to be able to view all applicant records, only the hiring Manager and VP of HR should be able to create salary applicant records.
What should the app builder recommend to meet this requirement?

Representatives at Universal Con use salesforce to record information for new Leads. When new prospects are added, an outbound message is sent to SAP with the Lead's info.

Universal Containers uses Contracts for agreements with customers. A sales manager is required to provide approval for contracts and director approval for any contract over $10,000.
Which two options should an app builder use to ensure all contracts route for the correct approval and also prevent the sales rep from making changes to the record while it is being approved?
