A project uses subcontracted resources from a sister company. What should the project manager do to ensure the subcontracted resources are smoothly integrated?

Facilitating a working session to review the ground rules is the most effective approach. This allows for active participation from the subcontracted resources, ensuring they understand and agree to the established norms and expectations. This collaborative review fosters buy-in and helps integrate them into the project team's operational framework, preventing misunderstandings and promoting smooth collaboration. Simply sharing the ground rules (option A) is passive and doesn't guarantee understanding or acceptance. Scheduling a formal meeting to cover mission and vision (option B) is important for overall project alignment but doesn't specifically address the practical aspects of team interaction and behavior. Organizing a team-bonding exercise (option C) can build rapport but is less direct in establishing operational guidelines than a focused working session on ground rules.
