|In response to increasingly competing environments, organisations are examining how their core business processes (BPs) may be redesigned to improve performance and responsiveness. However, there is a lack of approaches for evaluating BPR at design time and systematically applying BPR in the case of eligible models. The aim of this research is to: (a) evaluate the redesign capacity of BP models prior to implementation, (b) create a systematic and versatile BPR methodology, (c) correlate the evaluation and BPR methodologies to a unified and comprehensive approach and (d) demonstrate the above for a particular BPR method. A literature survey on the theoretical foundation of BPR and two separate Systematic Literature Reviews (SLRs) on BPR Evaluation and Application methodologies provide an overview of the current state of research and highlight the gap in systematic, generic methodologies that combine the assessment of redesign capacity of models at design time, with the application of BPR. The lack of a concept in literature that quantitatively depicts BPR applicability, led to the introduction of Model Plasticity. The concept is inspired by Neuroplasticity and is based on the calculation of internal model measures for predicting the applicability of RESEQ and PAR heuristics. Through a series of experiments and the use of logistic regression and the state-of-the-art Bender method, the author extracts and validates internal measure thresholds for the aforementioned heuristics. Following, the BPR Assessment framework is introduced for the systematic evaluation of the BPR capacity of input models based on their plasticity and external quality. The framework was created by applying the established DSRP methodology and incorporates essential redesign components that pass through interconnected phases. Two discrete operation modes of the framework based on partitioning clustering and proximity measurement are also proposed and presented in this research by using a BP model repository from literature. The operation modes are demonstrated for data-centric workflow optimization to highlight the straightforward and convenient application of the framework. A set of sixty-four real-life BP scenarios from the Greek Public Financial Management is modelled in the BPMN2.0 standard and measured for the validation of the framework. The validation demonstrates the multitude of benefits for the agencies of the Ministry of Finance and potentially to the whole Greek public sector, given the constant shift to digital transformation schemes. Finally, the author extended the framework with a new complementary artefact, the BPR Application framework, for the systematic application of BPR methods and combined them into a unified and comprehensive methodology. In this way, this research proposes a fully tested and validated methodology for the evaluation of the BPR capacity of models at design time, and a holistic methodology for systematically applying BPR to eligible cases.
