Semantic discovery and reuse of business process patterns
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.In modern organisations business process modelling has become fundamental due to the
increasing rate of organisational change. As a consequence, an organisation needs to
continuously redesign its business processes on a regular basis. One major problem
associated with the way business process modelling (BPM) is carried out today is the
lack of explicit and systematic reuse of previously developed models. Enabling the reuse of previously modelled behaviour can have a beneficial impact on the quality and
efficiency of the overall information systems development process and also improve the effectiveness of an organisationâs business processes. In related disciplines, like software engineering, patterns have emerged as a widely accepted architectural mechanism for reusing solutions. In business process modelling the use of patterns is quite limited apart from few sporadic attempts proposed by the literature. Thus, pattern-based BPM is not commonplace. Business process patterns should ideally be discovered from the empirical analysis of organisational processes. Empiricism is currently not the basis for the discovery of patterns for business process modelling and no systematic methodology for collecting and analysing process models of business organisations currently exists.
The purpose of the presented research project is to develop a methodological framework for achieving reuse in BPM via the discovery and adoption of patterns. The framework is called Semantic Discovery and Reuse of Business Process Patterns (SDR). SDR
provides a systematic method for identifying patterns among organisational data assets
representing business behaviour. The framework adopts ontologies (i.e., formalised
conceptual models of real-world domains) in order to facilitate such discovery. The
research has also produced an ontology of business processes that provides the
underlying semantic definitions of processes and their constituent parts. The use of
ontologies to model business processes represents a novel approach and combines
advances achieved by the Semantic Web and BPM communities. The methodological
framework also relates to a new line of research in BPM on declarative business
processes in which the models specify what should be done rather than how to
âprescriptivelyâ do it. The research follows a design science method for designing and
evaluating SDR. Evaluation is carried out using real world sources and reuse scenarios
taken from both the financial and educational domains
