Abstract [en]

Separation of concerns has long been an important strategy in the software systems development to cope with the complexity embedded in such systems. The same type of concerns, like security concerns, is often repeated in many modules of a system, which hinders the consistency, re-usability, change and maintenance of the system. Aspect orientation aims to separate and encapsulate these concerns to solve the complexity problem. This paper introduces the use of aspect orientation for case and adaptive case management through changing the rules that govern business processes on the fly. It introduces a taxonomy of such rules based on the declarative workflows approach. It also shows how so-called form-based case management systems could be extended to support aspect orientation to reduce the complexity problem.

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.
