The most common set of requirements defined by any operating system or software application is the physical computer resources, also known as hardware, A hardware requirements list is often accompanied by a hardware compatibility list (HCL), especially in case of operating systems. An HCL lists tested, compatible, and sometimes incompatible ...
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.
Requirements Triage or prioritization of requirements is another activity which often follows analysis. [4] This relates to Agile software development in the planning phase, e.g. by Planning poker, however it might not be the same depending on the context and nature of the project and requirements or product/service that is being built.
Architecturally significant requirements are those requirements that have a measurable effect on a computer system’s architecture. [1] This can comprise both software and hardware requirements. They are a subset of requirements , the subset that affects the architecture of a system in measurably identifiable ways.
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.
Open-system environment (OSE) reference model (RM) or OSE reference model (OSE/RM) is a 1990 reference model for enterprise architecture. It provides a framework for describing open system concepts and defining a lexicon of terms, that can be agreed upon generally by all interested parties.
Architectural requirements explain what has to be done by identifying the necessary integration of system structure and system behavior, i.e., system architecture of a system. In software engineering , they are called architecturally significant requirements , which is defined as those requirements that have a measurable impact on a software ...
ISO/IEC/IEEE 42010:2011 defines requirements on the description of system, software and enterprise architectures.It aims to standardise the practice of architecture description by defining standard terms, presenting a conceptual foundation for expressing, communicating and reviewing architectures and specifying requirements that apply to architecture descriptions, architecture frameworks and ...
