Abstract [en]

Complexity is a major concern which is aimed to be overcome by people through modelling. One way of reducing complexity is separation of concerns, e.g. separation of business process from applications. One sort of concerns are cross-cutting concerns i.e. concerns which are scattered and tangled through one or several models. In business process management, examples of such concerns are security and privacy policies. To deal with these cross-cutting concerns, the aspect orientated approach was introduced in the software development area and recently also in the business process management area. The work presented in this paper elaborates on aspect oriented process modelling. It extends earlier work by defining a mechanism for capturing multiple concerns and specifying a precedence order according to which they should be handled in a process. A formal syntax of the notation is presented precisely capturing the extended concepts and mechanisms. Finally, the relevance of the approach is demonstrated through a case study.

Abstract [en]

Coping with complexity in Information Systems and Software Engineering is an important issue in both research and industry. One strategy to deal with this complexity is through a separation of concerns, which can result in reducing the complexity, improving the re-usability, and simplifying the evolution.Separation of concerns can be addressed through the Aspect Oriented paradigm. Although this paradigm has been well researched in the field of programming, it is still in a preliminary stage in the area of Business Process Management. While some efforts have been made to propose aspect orientation for business process modeling, it has not yet been investigated how these models should be implemented, configured, run, and adjusted.Such a gap has restrained the enactment of aspect orientated business process models in practice.Therefore, this research enables the enactment of such models to support the separation of cross-cutting concerns in the entire business process management life-cycle.It starts by defining the operational semantics for the Aspect Oriented extension of the Business Process Model and Notation.The semantics specifies how such models can be implemented and configured, which can be used as a blueprint to support the enactment of aspect oriented business process models.The semantics is implemented in the form of artifacts, which are then used in a banking case study to investigate the current modeling technique.This investigation revealed new requirements, which should be considered in aspect oriented modeling approaches.Thus, the current modeling notation has been extended to include new requirements.The extended notation has been formalized, and investigated through re-modeling the processes in the case study. The results from this investigation show the need to refine the separation rules to support the encapsulation of aspects based on different business process perspectives. Therefore, the new refinement is proposed, formalized, and implemented.The implementation is then used as a prototype to evaluate the result through a case study.

2. Aspect-Oriented Business Process Management

Abstract [en]

Separation of concerns has long been considered an effective and efficient strategy to deal with complexity in information systems.One sort of concern, like security and privacy, crosses over other concerns in a system. Such concerns are called cross-cutting concerns.As a result, the realization of these concerns is scattered through the whole system, which makes their management difficult.

Aspect Orientation is a paradigm in information systems which aims to modularize cross-cutting concerns.This paradigm is well researched in the programming area, where many aspect-oriented programming languages have been developed, e.g., AspectJ.It has also been investigated in other areas, such as requirement engineering and service composition.In the Business Process Management (BPM) area, Aspect Oriented Business Process Modeling aims to specify how this modularization technique can support encapsulating cross-cutting concerns in process models.However, it is not clear how these models should be supported in the whole BPM lifecycle.In addition, the support for designing these models has only been limited to imperative process models that support rigid business processes.Neither has it been investigated how this modularization technique can be supported through declarative or hybrid models to support the separation of cross-cutting concerns for flexible business processes.

Therefore, this thesis investigates how aspect orientation can be supported over the whole BPM lifecycle using imperative aspect-oriented business process models. It also investigates how declarative and hybrid aspect-oriented business process models can support the separation of cross-cutting concerns in the BPM area.This thesis has been carried out following the design science framework, and the result is presented as a set of artifacts (in the form of constructs, models, methods, and instantiations) and empirical findings.

The artifacts support modeling, analysis, implementation/configuration, enactment, monitoring, adjustment, and mining cross-cutting concerns while supporting business processes using Business Process Management Systems. Thus, it covers the support for the management of these concerns over the whole BPM lifecycle. The use of these artifacts and their application shows that they can reduce the complexity of process models by separating different concerns.

Abstract [sv]

Att separera angelägenheter har länge ansetts som en effektiv och ändamålsenlig strategi för att hantera komplexitet i informationssystem. Sådana angelägenheter, till exempel säkerhet och enskildhet, kan skära tvärs över andra angelägenheter i ett system, och de kallas därför övergripande angelägenheter. Hanteringen av dessa kan vara utspridda genom hela systemet, vilket ökar komplexiteten.

Aspektorientering är ett paradigm som syftar till att modularisera övergripande angelägenheter. Detta paradigm är väl utforskat i programvaruområdet, där många aspektorienterade programmeringsspråk utvecklats. Paradigmet har också undersökts i andra områden som kravhantering och tjänstesammansättning. I ärendehanteringsområdet (BPM) syftar aspektorienterad processmodellering till att inkapsla övergripande angelägenheter i processmodeller. Det är dock inte klart hur dessa modeller bör stödjas i hela ärendehanteringslivscykeln. Dessutom är existerande stöd för att utforma dessa modeller begränsat till tvingande processmodeller som enbart stödjer rigida affärsprocesser. Det har inte heller undersökts hur denna modulariseringsteknik kan stödjas genom deklarativa eller hybridmodeller för att hantera separation av övergripande angelägenheter för flexibla affärsprocesser.

Därför undersöker denna avhandling hur aspektorientering kan stödjas i hela ärendehanteringslivscykeln med hjälp av tvingande aspektorienterade affärsprocessmodeller. Den undersöker också hur deklarativa och hybridaspektorienterade affärsprocessmodeller kan stödja separation av övergripande angelägenheter i BPM-området. Avhandlingens resultat bygger på designvetenskaplig forskning, och de presenteras som en uppsättning av artefakter (i form av konstruktioner, modeller, metoder och instansieringar) och som empiriska iakttagelser.

De framtagna artefakterna stödjer modellering, analys, genomförande, konfiguration, övervakning och modifiering av övergripande angelägenheter i affärsprocesser. Artefakterna erbjuder stöd för hantering av dessa angelägeheter för hela ärendehanteringslivscykeln. Användningen av dessa artefakter och deras tillämpningar visar att de kan minska komplexiteten i processmodeller genom att separera övergripande angelägenheter.
