Comprehensive and Detailed Explanation From Exact Extract of Documents:

The disadvantage of subcontracting is less control over performance. The L5M5 study guide (p.156)

notes that while subcontracting allows access to specialist expertise, it creates additional risks for

project delivery, as the main contractor remains accountable for subcontractor performance.

Problems such as delays, quality issues, or non-compliance can occur, and these are more difficult to

manage indirectly. Increased costs (A) are not always true since subcontracting can be cost-effective,

while lower quality (B) depends on subcontractor capability. Compliance with the law (D) is a

requirement, not a disadvantage. Procurement professionals must carefully manage subcontractors

through clear contracts, monitoring, and accountability measures.
