Emergent Properties

Emergent Properties

emergent properties 1

properties of the system as a whole that depend on the system components and relationships

emergent properties 2

a consequence of the relationships between system components

emergent properties 3

can only be assessed and measured once the components have been integrated into a system

volume

the total space occupied. depends on how components are arranged and connected

reliability

depends on component reliability but unexpected interactions can cause new types of failures

security

a complex property that cannot easily be measured

repairability

reflects how easy it is to fix a problem with the system once it has been discovered. depends on diagnosing the problem, accessing the faulty components and modifying/ replacing them

usability

reflects how easy it is to use the system. depends on technical system components, its operators and operating environment.

functional emergent properties

appear when all the parts of a system work together to achieve some objective

non functional emergent properties

relate to the behavior of the system in its operational environment. e.g., reliability, performance, safety
