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 ...
Capability Maturity Model. 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 ...
Software performance testing. 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 ...
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 ...
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.
The process areas below and their maturity levels are listed for the CMMI for Development model: Maturity Level 2 - Managed. CM - Configuration Management. MA - Measurement and Analysis. PMC - Project Monitoring and Control. PP - Project Planning. PPQA - Process and Product Quality Assurance. REQM - Requirements Management.
Consider a quality characteristic with a target of 100.00 μm and upper and lower specification limits of 106.00 μm and 94.00 μm, respectively. If, after carefully monitoring the process for a while, it appears that the process is out of control and producing output unpredictably (as depicted in the run chart below), one can't meaningfully estimate its mean and standard deviation.
