: ''See the main article at [[Performance engineering]]''

Performance engineering is the discipline encompassing roles, skills, activities, practices, tools, and deliverables used to meet the [[non-functional requirements]] of a designed system, such as increase business revenue, reduction of system failure, delayed projects, and avoidance of unnecessary usage of resources or work.

Several common activities have been identified in different methodologies:
* Identification of critical [[business processes]].
* Elaboration of the processes in [[use cases]] and system volumetrics.
* System construction, including performance tuning.
* Deployment of the constructed system.
* Service management, including activities performed after the system has been deployed.
