A software requirements specification (SRS) is a description of a software system to be developed.It is modeled after the business requirements specification.The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
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.
The activities related to working with software requirements can broadly be broken down into elicitation, analysis, specification, and management. [3] Note that the wording Software requirements is additionally used in software release notes to explain, which depending on software packages are required for a certain software to be built ...
In systems engineering and software engineering, requirements analysis focuses on the tasks that determine the needs or conditions to meet the new or altered product or project, taking account of the possibly conflicting requirements of the various stakeholders, analyzing, documenting, validating, and managing software or system requirements.
A System Requirements Specification (SysRS) (abbreviated SysRS to be distinct from a software requirements specification (SRS)) is a structured collection of information that embodies the requirements of a system. [1]
Examples: The Design Specification must implement the SRS; and, the Construction phase artifacts must implement the Design Specification. So, when these words are defined in common terms, the apparent contradiction disappears. Both the SRS and the software must be validated. The SRS can be validated statically by consulting with the stakeholders.
Business requirements in the context of software engineering or the software development life cycle, is the concept of eliciting and documenting business requirements of business users such as customers, employees, and vendors early in the development cycle of a system to guide the design of the future system.
The goal of the Research and Elicitation stage is to understand and research the business drivers, goals and objectives, project artifacts created to date, and create workflow to help illustrate the current state and desired future state. It ultimately defines the project's mid-level requirements.
