# Performance Engineering

"**Performance engineering** encompasses the techniques applied during a [systems development life cycle](https://en.m.wikipedia.org/wiki/Systems_development_life_cycle) to ensure the [non-functional requirements](https://en.m.wikipedia.org/wiki/Non-functional_requirement) for performance (such as [throughput](https://en.m.wikipedia.org/wiki/Throughput), [latency](https://en.m.wikipedia.org/wiki/Latency_\(engineering\)), or [memory](https://en.m.wikipedia.org/wiki/Computer_memory) usage) will be met. It may be alternatively referred to as **systems performance engineering** within [systems engineering](https://en.m.wikipedia.org/wiki/Systems_engineering), and **software performance engineering** or [application performance engineering](https://en.m.wikipedia.org/wiki/Application_performance_engineering) within [software engineering](https://en.m.wikipedia.org/wiki/Software_engineering)." - Wikipedia
