In an effort to streamline client interaction processes, a business is transitioning to a sophisticated platform designed for this purpose. The analytics division requires permissions to generate reports and review client data, while the account management division needs the ability to engage with and alter client records. What is the BEST strategy for assigning the appropriate level of system access in accordance with each division's responsibilities?
Institute a policy where access is determined by the seniority of the personnel within the organization
Grant all divisions the same level of access to simplify management of the new platform
Allow division heads to grant access as they see fit for their respective teams
Utilize a predefined set of roles that are specific to user job functions to regulate access within the platform
