Service-based Processes: Design for business and technology
KTH, School of Information and Communication Technology (ICT), Computer and Systems Sciences, DSV. (SYSLAB)
2008 (English)Doctoral thesis, comprehensive summary (Other scientific)
Abstract [en]

The concepts of processes and services can be used to structure both businesses and software systems. From a business perspective, the use of processes promises efficient management of organizations. From a software perspective, executable process descriptions provide a way to structure software systems according to the business process the systems should support. Furthermore, the concept of software services allows systems to be partitioned in a modular fashion, thereby enabling large-scale system integration on a technical level. By combining process descriptions with software services in service-based processes, it is feasible to address both business and more technical software needs.

Aligning the business and software perspectives of processes and software services is, however, challenging, since implemented executable processes and software services need to cater for operational and strategic business needs as well as existing legacy software systems.

In this thesis, several instruments are presented that aim at aiding the design and evolution of service-based processes. The aligning of operational business and software perspectives on process descriptions is addressed by the introduction of business and technical process model levels. These levels can be aligned by the use of a set of model transformations and associated transformation rules. Furthermore, the aligning is aided by introducing means for achieving flexibility on both the business and technical model levels. The development of service-based processes from a strategic business point of view is aided by the introduction of novel models and methods for goal-based design of software services. Taken together, the instruments can be used for the design and evolution of service-based processes.

Abstract [en]

Composition of software services is a fundamental part in supporting enterprise business processes. Designed properly, executable processes can be used to closely support business processes by the integration of existing software services. In order to support business processes the design of the executable process must closely follow the business events and activities, as perceived by business actors. However, the design must also consider technical issues such as limitations in existing technology and systems. In this paper we examine how technical system constraints influence the realization of business processes. Based on this examination we present a set of realization types that describes the transformation from a business process into its realization as an executable process. We also propose design criteria that need to be adhered to in order to cater to both business and technical needs.

Abstract [en]

In most organizations, business process realizations must be aligned with existing systems,which can impose specific requirements. Currently, however, there is no way to track the alignment between business processes and corresponding technical implementations. The authors' proposed framework offers a systematic way to classify and assess technical realizations of business processes.

Abstract [en]

When designing executable enterprise processes, the alignment between business and technical requirements is still one of the central problems. Process specifications obtained from the pure business perspective commonly cannot be executed "as-is" due to constraints of information systems given in the form of existing software services. In this paper we introduce several concepts targeted towards aligning business processes and service-based systems. The notion of realization levels is introduced to discern the level of business conformance. Furthermore, a model of system constraints is introduced to guide the developer to process realizations with high business conformance. By. the combined use of the concepts, structured development and evolution of process realizations is enabled by continuous tracking of the alignment between business and the supporting technology.

Abstract [en]

When realizing executable business process models, in most situations process specifications collide with specific properties of existing services. In this paper we propose an approach for relaxation of the business process specification to enable flexible integration between the process and existing services. The approach is based on the notion of visibility, which allows a categorized relaxation of the process specification by not requiring every process state to be distinguished after the process is realised with existing services. The categories of visibility presented in this paper are applied by indicating flexible elements in the process design phase. The presented approach stimulates the alignment between business processes and existing services, facilitating a larger scale of transparent process realisations.

Abstract [en]

By the use of Web Service technologies and the Internet it is possible to lay the foundation for virtual value chains that cross enterprise boundaries. As the number of services and their interaction grow, it is evident that the flow of message exchange between services needs to be coordinated in a structured way. Executable process languages such as BPEL are proposed as an instrument for the coordination of services. Executable processes must be designed such that they solve technical coordination problems as well as provide a fundament for organizations to manage and monitor the progress of the business. In this paper we examine how the design of executable processes is affected by both technical and business issues. Furthermore, we examine a set of architectures that enable the use of executable processes to cater to both business and technical needs. We provide fundamental guidelines on how to apply the architectures.

Abstract [en]

A broader use of e-services for cross enterprise collaboration requires the services to be analysed and designed with a clear business focus. From a business perspective, the e-services must support the primary values that an organization strives for. From an operational perspective, the e-services must be devised such that they support the day-to-day activities in the business. In this paper, we report on an effort to use value models and "service process models" as the foundation for analysis and design of e-services. Value models facilitate the exploration of new e-services, whereas service process models relate e-services to specific activities in an organization's business processes. We elicited a set of principles and models for analysis and design of e-services, and we discussed the experiences of practicing the principles in a project from the health sector. Having a well-defined alignment of software and business values provides benefits for service requirement gathering, service identification and service validation.

Abstract [en]

E-services are used as the cornerstones for modeling interaction points of cooperating IT systems, within and between enterprises. So far, research and development of e-services have mainly focused on an operational perspective, such as the development of standards for message exchanges and service coordination. However, on a strategic level, the success of e-services depends on its ability to work as a catalyst for the business values that are being exchanged. In this paper, we present an approach that utilize value and goal models as the foundation for designing e-services. The approach can be used to strategically ensure that the developed e-services support the desired business values for involved actors. A case study from the Swedish health sector is used to ground and apply the presented approach.
