If a two-tier employment model is required with only single assignment, what option is suitable for configuration?

The appropriate configuration for a two-tier employment model with only a single assignment would be a combination of Single Assignment or Single Assignment with Contract.

In a two-tier employment model, organizations aim to distinguish between different categories of employees, often between local and global roles, or between different types of employment agreements. A Single Assignment structure allows for each employee to have only one main job role, streamlining management and simplifying reporting structures. Including "Single Assignment with Contract" expands the flexibility by permitting the addition of contract terms which might be necessary depending on the organization’s needs, covering aspects such as temporary roles or specific project-based agreements.

This configuration ensures that the organization aligns with the desired strategic approach while maintaining clarity in assignments and contracts applicable to each employee. The other configurations suggest options that introduce complexity or arrangements not suited to a two-tier model solely focused on single assignments.
