# Systems engineering Systems engineering is the interdisciplinary life-cycle discipline that designs, integrates, and manages complex engineered systems so that components work synergistically under constraints of requirements, reliability, maintainability, risk, and human factors. It employs [[Systems_thinking|systems thinking]], modeling languages (SysML), V-models, trade-off analysis, and "ilities" to deliver optimized, verifiable wholes from concept through decommissioning. ## Reveal %%REVEAL:mermaid%% %%REVEAL:svg%% --- *Concept aligned with [Wikipedia](https://en.wikipedia.org/wiki/Systems_engineering); adapted text, where present, is licensed [CC BY-SA 4.0](https://creativecommons.org/licenses/by-sa/4.0/).* ## Overview The discipline draws its theory from [[Systems_science|systems science]] and [[Systems_theory|systems theory]], its regulation-and-goal-seeking vocabulary from [[Cybernetics|cybernetics]], [[Control_theory|control theory]], and [[Feedback|feedback]] (both [[Negative_feedback|negative]] and [[Positive_feedback|positive]]), and its decision machinery from [[Operations_research|operations research]] and [[Mathematical_optimization|mathematical optimization]]. Assurance rests on [[Reliability_engineering|reliability engineering]] and [[Fault_tree_analysis|fault tree analysis]]; behavior-over-time questions route through [[System_dynamics|system dynamics]] on the pattern of [[Jay_Wright_Forrester|Jay Wright Forrester]]. Because every engineered whole is also a [[Complex_system|complex system]] embedded in an [[Ecosystem|ecosystem]] of stakeholders, practitioners lean on pioneers from [[Norbert_Wiener|Norbert Wiener]] to [[Qian_Xuesen|Qian Xuesen]], and on the [[Information_system|information system]] backbone that carries a design from requirement to fielded [[System|system]]. ## Wikipedia : Wikitube **Strict pair:** [Wikipedia](https://en.wikipedia.org/wiki/Systems_engineering) : [Wikitube](https://en.wikitube.io/wiki/Systems_engineering) ## Previous hub tags Hubs: `Systems`.
