Editing Systems engineering (section)

===Systems engineering processes===
Systems engineering processes encompass all creative, manual, and technical activities necessary to define the product and which need to be carried out to convert a system definition to a sufficiently detailed system design specification for product manufacture and deployment. Design and development of a system can be divided into four stages, each with different definitions:<ref name="lienig">{{Cite book|author1=J. Lienig|author2=H.

* Task definition (informative definition)
* Conceptual stage (cardinal definition)
* Design stage (formative definition)
* Implementation stage (manufacturing definition)

Depending on their application, tools are used for various stages of the systems engineering process:<ref name="SEF01"/>
