ADAPTATION OF SERVICE PROTOCOLS
The originality of the proposed solution comes from the interdisciplinary naturę of
service protocols and their adaptation based on the integration of the process approach,
the service-oriented paradigm, and networks, especially social ones. Another original
aspect of Picard's approach is the fact that the proposed adaptation method is both
normative and collaborative, encompassing human factors, such as tacit knowledge and
social relations, that are not supported in purely technical systems.
From a review by Professor Jerzy Brzeziński
The originality of the results of Picard's works comes from a generalization of the
service-oriented paradigm to support the collaboration of people, information systems
and/or organizations. [...] Picard demonstrates that protocols are a universal approach
that can be applied to both global and local organizations.
