Design specification design specifications describe how a system performs the requirements outlined in the functional requirements depending on the system, this can include instructions on testing specific requirements, configuration settings, or review of functions or code.
Design documents include information about the programmatic design of the application under development this design information has limited usage but is necessary to document the intellectual.

There may be many levels of design documents (eg, system- or component-level) a technical specification describes the minute detail of either all or specific parts of a design, such as: the signature of an interface, including all data types/structures required (input data types, output data types, exceptions. Ideally, an agile document is just barely good enough, or just barely sufficient, for the situation at handdocumentation is an important part of agile software development projects, but unlike traditionalists who often see documentation as a risk reduction strategy, agilists typically see documentation as a strategy which increases overall project risk and therefore strive to be as efficient.
Design documents are incrementally and iteratively produced during the system development life cycle, based on the particular circumstances of the information technology (it) project and the system development methodology used for developing the system. Systems design is the process of defining the architecture, modules, interfaces, and data for a system to satisfy specified requirementssystems design could be seen as the application of systems theory to product developmentthere is some overlap with the disciplines of systems analysis, systems architecture and systems engineering.
