To be used efficiently, all computer software needs certain hardware components or other software resources to be present on a computer. [1] These prerequisites are known as (computer) system requirements and are often used as a guideline as opposed to an absolute rule. Most software defines two sets of system requirements: minimum and recommended.
Peopleware can refer to anything that has to do with the role of people in the development or use of computer software and hardware systems, including such issues as developer productivity, teamwork, group dynamics, the psychology of programming, project management, organizational factors, human interface design and human–machine interaction.
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 ...
Requirements analysis can be a long and tiring process during which many delicate psychological skills are involved. New systems change the environment and relationships between people, so it is important to identify all the stakeholders, take into account all their needs, and ensure they understand the implications of the new systems.
They are usually architecturally significant requirements that require architects' attention. [1] In software architecture, these attributed are known as "architectural characteristic" or non-functional requirements. Note that it's software architects' responsibility to match these attributes with business requirements and user requirements ...
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.
"Procedures are to people what software is to hardware" is a common analogy that is used to illustrate the role of procedures in a system. People: Every system needs people if it is to be useful. Often the most overlooked element of the system is the people, probably the component that most influences the success or failure of information systems.
Requirements inception or requirements elicitation – Developers and stakeholders meet; the latter are inquired concerning their needs and wants regarding the software product. Requirements analysis and negotiation – Requirements are identified (including new ones if the development is iterative), and conflicts with stakeholders are solved.
