In the VITAL/design project we develop techniques to design a network of
business systems to provide ICT services. Classical methods such as
Information Engineering design modular systems by means of CRUD
analysis but in a networked business this is not sufficient, as
ownership is not taken into account. Modular networks involve decisions
different kinds of ownership (of data, of processes, of systems) each
with different cost and revenue structures, communication requirements,
and access restrictions.
We investigate the use of value-based techniques to make these in practice
by means of case studies, design new techniques and validate them in
simulated case studies and action research. Based on case studies of
service allocation to business systems, we propose techniques to make
the trade-offs involved in these decisions. This will be embedded in
"classical" architecture methods such as Information Engineering, and in
e3value as a requirements engineering methods. We will validate the result
in simulated case studies.
