Professional Services
The services provide
the Technology, Assets
& Resources that
individuals never can
organize separately
The services exchangethe Technology, Assets
& Resources between
experts & clients
The services give an
additional meaning to the
bundled Technology, Assets
& Resources

What are good conceptual C-models ? Rich Semantic Expressiveness
Donts : Hierarchies
Un-ambigous Models
Donts : Many to many relations
Optional to optional relations
Search for normalized models
Provide Guidance for unknown unknowns
Donts : Nothing is wrong so everything is good
A mystery is not a puzzle

Formal Concept Analysis is one approach
The symbols (attributes) describe
one view on the subjects
FCA discovers the concepts and
orders them in a LATTICE
(= desired non-hierarchical structure)
