What term refers to installing and maintaining a product after sale, including training?

• A. After-sales support
• B. Warranty service
• C. Field service
• D. Customer care

Answer: (C)

Field service is the term that refers to installing and maintaining a product after sale, and it often includes training the customer on how to use and care for the product. This work is typically performed on-site at the customer’s location by service technicians, covering activities like installation, preventive maintenance, diagnostics, repairs, upgrades, and the training needed to operate the product effectively. That combination—on-site setup, ongoing maintenance, and customer training—is what distinguishes field service from other post-sale terms.

After-sales support is broader and can include remote help and general assistance, not necessarily on-site. Warranty service deals with repairs or replacements covered under warranty terms and doesn’t inherently include setup or training. Customer care focuses on the overall relationship and satisfaction rather than the technical servicing of the product at the customer site.
