Where must Product Service Codes be identified?

Product Service Codes (PSCs) must be identified within Contract Line Items because these codes are essential for classifying and describing the products and services being acquired under a contract. The PSCs serve as a standardized coding system that helps in identifying the specific products or services, enabling better tracking, reporting, and management of federal purchases.

Including PSCs in Contract Line Items ensures clear communication regarding the nature of the goods or services, which is crucial for contract compliance, performance evaluation, and financial management. This classification facilitates data analysis, assists in procurement planning, and aligns with the federal government's initiatives for efficient acquisition.

While the other options mention important documents and processes related to contracting, they do not specifically serve as the designated location for PSC identification. Contract Performance Reports, Project Management Plans, and Summary of Requirements focus on different aspects of contract management and do not inherently require the listing of service codes as part of their standard content.
