Performance engineering encompasses the techniques applied during a systems development life cycle to ensure the non-functional requirements for performance (such as throughput, latency, or memory usage) will be met. It may be alternatively referred to as systems performance engineering within systems engineering, and software performance ...
The Capability Maturity Model ( CMM) is a development model created in 1986 after a study of data collected from organizations that contracted with the U.S. Department of Defense, who funded the research. The term "maturity" relates to the degree of formality and optimization of processes, from ad hoc practices, to formally defined steps, to ...
In software quality assurance, performance testing is in general a testing practice performed to determine how a system performs in terms of responsiveness and stability under a particular workload. [ 1] It can also serve to investigate, measure, validate or verify other quality attributes of the system, such as scalability, reliability and ...
4+1 is a view model used for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". [ 1] The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers, system engineers, and project managers. The four views of the model are logical ...
In systems engineering, information systems and software engineering, the systems development life cycle ( SDLC ), also referred to as the application development life cycle, is a process for planning, creating, testing, and deploying an information system. [ 1] The SDLC concept applies to a range of hardware and software configurations, as a ...
Software development. In software engineering, a software development process or software development life cycle is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management.
Perceived performance, in computer engineering, refers to how quickly a software feature appears to perform its task. The concept applies mainly to user acceptance aspects. The amount of time an application takes to start up, or a file to download, is not made faster by showing a startup screen (see Splash screen) or a file progress dialog box.
The Personal Software Process ( PSP) is a structured software development process that is designed to help software engineers better understand and improve their performance by bringing discipline to the way they develop software and tracking their predicted and actual development of the code. It clearly shows developers how to manage the ...
