Configuration Control: includes the evaluation of all change-requests and change-proposals, and their subsequent approval or disapproval. It covers the process of controlling modifications to the system's design, hardware, firmware, software, and documentation.
Functionality, usability, reliability, performance and supportability are together referred to as FURPS in relation to software requirements. Agility in working software is an aggregation of seven architecturally sensitive attributes: debuggability, extensibility, portability, scalability, securability, testability and understandability.
Often, configuration pertains to the choice of hardware, software, firmware, and documentation. Along with its architecture, the configuration of a computer system affects both its function and performance. The configuration of a computer is typically recorded in a configuration file. In modern computer systems, this is created and updated ...
The term configuration item (CI) refers to the fundamental structural unit of a configuration management system. [1] Examples of CIs include individual hardware or software components. The configuration-management system oversees the life of the CIs through a combination of processes and tools by implementing and enabling the fundamental ...
Performance engineering within systems engineering encompasses the set of roles, skills, activities, practices, tools, and deliverables applied at every phase of the systems development life cycle which ensures that a solution will be designed, implemented, and operationally supported to meet the performance requirements defined for the solution.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
Software configuration management (SCM), a.k.a. software change and configuration management (SCCM), [1] is the software engineering practice of tracking and controlling changes to a software system; part of the larger cross-disciplinary field of configuration management (CM). [2] SCM includes version control and the establishment of baselines.
It is a process because a sequence of steps is prescribed to produce or change the architecture, and/or a design from that architecture, of a hardware system within a set of constraints. It is a discipline because a body of knowledge is used to inform practitioners as to the most effective way to design the system within a set of constraints.
