When switching to control model s of business system, a new part of the
sufficient-conditien -like part of guality definition for a given input informa-
tion acerues, Fach input information being purposeful, induces a finite set
of goals business system wants to achieve,at a given control herizon, A number
og golas ,the level of their consistency and other properties modern control £kc
theory deals with , could be considered as a part of guality of input informatior

In addition to that , output information does net in general serve as a
domain of geal funotionals, Insteda, criteria are being sought as intermediate
link between them so as to find some pragmatic ways of centrol and management
of business system. Again, number and all other standard system theory
categories pertaining criteria could be the components of guality definition
for given input information,

Pollowing the analegy for the case of output information we propose to include
transformations of output information into oriteria as well as transformations
of criteria into goals with respect to their fundamental properties as component
ef information guality description,

Since a systems approach may have many different mathematical structures
involved, an examination as proposed above can take place in some preselected
manner, This project, in its first stage would amount to linear short run
models which enable us to formulate a tool for non-terminal control over a
business system of an arbitrary type as much as possihle,Following a general xx
systems theory we are to find structural properties of business system so
that results would enable someone to give a diagnostic cross-section over
the set of chains "input information-output information-coriteria -goals" which
are rolling through a business system in genegal,

The guality of information thus consists of input information as primary set
of guality components (in the classical sense), Starting from this primary set
we intend to generate and optimise a secondary set of guality components 5
where this set consists of output information, criteria and goals belonging
to the same bisiness system as input information, Transformations which
interconnect these four sets could sometimes be variable ; in such a case
we can suggest the optimised transformations (if they exist) in order to improve
the three sets mukk of the secondary part of guality. It may give an additional
boost to business system measured by levels of goals and at the gxx same time
increasing the guality of input information. It is worth to notice that we would
like to maintain the guality definition even in a case where transforma tions

are not capable of formal presentation,
