What are the disadvantages of subcontracting?

Subcontracting can lead to reduced control over the quality of work, as the primary contractor may have limited oversight of subcontractors' practices. It can also result in communication challenges and misalignment of goals, potentially affecting project timelines and outcomes. Additionally, relying on subcontractors can create dependency and increase overall costs if not managed effectively. Lastly, there may be legal and liability concerns if subcontractors fail to meet contractual obligations.
