Documentation development may involve document drafting, formatting, submitting, reviewing, approving, distributing, reposting and tracking, etc., and are convened by associated standard operating procedure in a regulatory industry. It could also involve creating content from scratch. Documentation should be easy to read and understand.
Historically, most classes of technical documentation lacked universal conformity for format, content and structure. Standards are being developed to redress this through bodies such as the International Organization for Standardization(ISO), which has published standards relating to rules for preparation of user guides, manuals, product specifications, etc. for technical product documentation.
Requirements should be validated before the software product as a whole is ready (the waterfall development process requires them to be perfectly defined before design starts; but iterative development processes do not require this to be so and allow their continual improvement). Examples of artifact validation:
An ICD is the umbrella document over the system interfaces; examples of what these interface specifications should describe include: The inputs and outputs of a single system, documented in individual SIRS (Software Interface Requirements Specifications) and HIRS (Hardware Interface Requirements Specifications) documents, would fall under "The Wikipedia Interface Control Document".
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
[5] [6] Requirements quality can be improved through these and other methods: Visualization. Using tools that promote better understanding of the desired end-product such as visualization and simulation. Consistent use of templates. Producing a consistent set of models and templates to document the requirements. Documenting dependencies ...
A functional specification is the more technical response to a matching requirements document, e.g. the Product Requirements Document "PRD" [citation needed]. Thus it picks up the results of the requirements analysis stage. On more complex systems multiple levels of functional specifications will typically nest to each other, e.g. on the system ...
Requirements engineering (RE) [1] is the process of defining, documenting, and maintaining requirements [2] in the engineering design process. It is a common role in systems engineering and software engineering .
