  Classic approaches to General Systems Theory often adopt an individual
perspective and a limited number of systemic classes. As a result, those
classes include a wide number and variety of systems that result equivalent to
each other. This paper introduces a different approach: First, systems
belonging to a same class are further differentiated according to five major
general characteristics. This introduces a "horizontal dimension" to system
classification. A second component of our approach considers systems as nested
compositional hierarchies of other sub-systems. The resulting "vertical
dimension" further specializes the systemic classes and makes it easier to
assess similarities and differences regarding properties such as resilience,
performance, and quality-of-experience. Our approach is exemplified by
considering a telemonitoring system designed in the framework of Flemish
project "Little Sister". We show how our approach makes it possible to design
intelligent environments able to closely follow a system's horizontal and
vertical organization and to artificially augment its features by serving as
crosscutting optimizers and as enablers of antifragile behaviors.
