Which of the following does a commercial, off-the-shelf system usually require?

A commercial, off-the-shelf system, often called a COTS solution, is a ready-made product purchased from a vendor rather than built from scratch. Because it is already designed, tested, packaged, and supported by the vendor, it usually requires only minimal customization to meet business needs. A project manager should expect configuration, integration, user setup, training, and limited tailoring, but heavy customization can increase cost, schedule risk, maintenance complexity, and vendor-support limitations. Cloud infrastructure may be used for some COTS products, but it is not always required. A privacy assessment may be required depending on the data handled, but not universally. A dedicated IP address is a technical requirement that depends on architecture and security design, not on COTS itself.
