A software requirements specification (SRS) is a description of a software system to be developed. It is modeled after business requirements specification (CONOPS). 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. Show Software requirements specification establishes the basis for an agreement between customers and contractors or suppliers on how the software product should function (in a market-driven project, these roles may be played by the marketing and development divisions). Software requirements specification is a rigorous assessment of requirements before the more specific system design stages, and its goal is to reduce later redesign. It should also provide a realistic basis for estimating product costs, risks, and schedules.[1] Used appropriately, software requirements specifications can help prevent software project failure.[2] The software requirements specification document lists sufficient and necessary requirements for the project development.[3] To derive the requirements, the developer needs to have clear and thorough understanding of the products under development. This is achieved through detailed and continuous communications with the project team and customer throughout the software development process. The SRS may be one of a contract's deliverable data item descriptions[4] or have other forms of organizationally-mandated content. Typically a SRS is written by a technical writer, a systems architect, or a software programmer.[5] Structure[edit]An example organization of an SRS is as follows:[6]
Requirements smell[edit]Following the idea of code smells, the notion of requirements smell has been proposed to describe issues in requirements specification where the requirement is not necessarily wrong but could be problematic.[7] Examples of requirements smells are subjective language, ambiguous adverbs and adjectives, superlatives and negative statements.[7] See also[edit]

What should I write in performance requirements?When writing a performance requirement, it should be quantifiable and define at minimum, the context and expected throughput, response time, max error rate, and sustained amount of time.
What is the definition of performance requirements?Performance requirements means the operating capabilities, maintenance, and reliability characteristics of a system that are determined to be necessary for it to fulfill the requirement for which the system is designed.
What are functional and performance requirements?Functional requirements are unique and are the heart of what your system is expected to do and capabilities it needs to have. Performance requirements tell us how the function will be done – how well, how often, how much, how many, etc.
