A RS can contain both written and graphical (models) information if necessary. Example: Software requirements specification (SRS). Requirements validation – Checking that the documented requirements and models are consistent and meet the stakeholder's needs. Only if the final draft passes the validation process, the RS becomes official.
Identify "domain constraints" (i.e., characteristics of the business environment specific to the application domain) that limit the functionality or performance of the system or product to be built; Define one or more requirements elicitation methods (e.g., interviews, focus groups, team meetings)
Requirements specification is the synthesis of discovery findings regarding current state business needs and the assessment of these needs to determine, and specify, what is required to meet the needs within the solution scope in focus. Discovery, analysis, and specification move the understanding from a current as-is state to a future to-be state.
[1] A specification or spec is a set of requirements that is typically used by developers in the design stage of product development and by testers in their verification process. With iterative and incremental development such as agile software development, requirements are developed in parallel with design and implementation.
Functional requirements are supported by non-functional requirements (also known as "quality requirements"), which impose constraints on the design or implementation (such as performance requirements, security, or reliability). Generally, functional requirements are expressed in the form "system must do <requirement>," while non-functional ...
The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.
The process of identifying, modelling and documenting the data requirements of the system being designed. The result is a data model containing entities (things about which a business needs to record information), attributes (facts about the entities) and relationships (associations between the entities).
A functional specification (also, functional spec, specs, functional specifications document (FSD), functional requirements specification) in systems engineering and software development is a document that specifies the functions that a system or component must perform (often part of a requirements specification) (ISO/IEC/IEEE 24765-2010).
