SYSTEM SPECIFICATIONS

A system specification describes the operational and performance requirements of a system, such as a computer. It is considered a high-level document that dictates global functions.

System specifications help to define the operational and performance guidelines for a system. It may outline how the system is expected to perform, and what that may include. Key specifications may include interface definitions, document design rules and functional areas.

When purchasing software or a computer, system specifications may be outlined during the evaluation process and agreed upon during the payment process. The specifications may determine security access. Many organizations will offer templates and resources to help facilitate the adherence of system specifications. In some cases, system specifications can be quite specific and difficult to follow without these guidelines
