In systems engineering, cohesion refers both to the property of natural and social systems that similar elements are attracted to each other and to ability to operate in a threat environment.  The context determines which definition is appropriate.   


Please note that if there is more than one definition, it is very important to provide information on the context of the different terms and to explain to the user why it is not possible to identify only one definition.  For example, is this an emerging concept for which there is still much research to be done?  Or have two different definitions emerged as the result of two different disciplines interacting with systems engineering?
