Enabling Process Support for Advanced Applications with the AristaFlow BPM Suite

A process-aware information system (PAIS) will be not accepted by end users if its software clients do not support their native workflows or are too complex for them. When implementing business processes based on process management technology important issues are, therefore, how end-users can participate in the execution of the processes and how this can be accomplished as intuitively as possible. This becomes extremely important if high flexibility demands need to be fullled during process execution, while PAIS robustness and error safety need to be assured. In this software demonstration we show how the AristaFlow BPM Suite - an adaptive process management system developed by us - was applied to challenging applications in domains like healthcare, logistics, disaster management, and software development. The implementation of adaptive software clients in these different applications particularly proves the benefits provided by an open application programming interface (API) as offered by AristaFlow

Enabling Flexible and Robust Business Process Automation for the Agile Enterprise

During the last decade process-aware information systems (PAISs) have become increasingly popular to digitize business processes and to effectively support them at the operational level. In many application domains, however, PAISs will not be accepted by users if rigidity comes with them. Ensuring PAIS robustness, in turn, becomes extremely complicated if high flexibility demands need to be fulfilled. To cope with the dynamic nature of business processes, we developed AristaFlow, a next generation process management technology that enables comprehensive process lifecycle support. In addition to standard process management services, AristaFlow can handle exceptions, change the execution of running business cases on the fly, efficiently deal with uncertainty, and support the evolution of business processes over time. This paper discusses how AristaFlow assists the various stakeholders of a PAIS to cope with errors and exceptional situations, while still meeting robustness needs. In particular, we focus on new error handling procedures and capabilities utilizing the flexibility provided by ad-hoc changes

Robust and Flexible Error Handling in the AristaFlow BPM Suite

Process-aware information systems will be not accepted by users if rigidity or idleness due to failures comes with them. When implementing business processes based on process management technology one fundamental goal is to ensure robustness of the resulting process-aware information system. Meeting this goal becomes extremely complicated if high flexibility demands need to be fullled. This paper shows how the AristaFlow BPM Suite assists process participants in coping with errors and exceptional situations in a flexible and robust way. In particular, we focus on novel error handling procedures and capabilities using the flexibility provided by ad-hoc changes not shown in other context so far

Enabling Time-Aware Process Support with the ATAPIS Toolset

The proper handling of temporal constraints is crucial for business processes in many application domains. Contemporary process-aware information systems (PAIS), however, lack a sophisticated support of time-aware processes. First of all, at design time it should be possible to specify the temporal constraints of a business process. In turn, this should be accompanied by checking the respective time-aware process schema for inconsistencies that may emerge due to hidden interdependencies among the temporal constraints. The latter is crucial to enable a robust and error-free execution of the time-aware process schema. At run time, corresponding process instances need to be monitored for violations of their temporal constraints. This demo paper presents the ATAPIS Toolset for modeling and enacting time-aware processes. The toolset is based on AristaFlow BPM Suite---an industrial-strength process management system. The ATAPIS Toolset enables process engineers to correctly specify and implement time-aware processes. Further, time-aware process instances can be efficiently executed, whilst monitoring their temporal constraints. Altogether, the ATAPIS Toolset covers the temporal perspective of processes at design as well as run time in a comprehensive way

Enabling Flexibility in Process-Aware Information Systems: Challenges, Methods, Technologies

In today’s dynamic business world, the success of a company increasingly depends on its ability to react to changes in its environment in a quick and flexible way. Companies have therefore identified process agility as a competitive advantage to address business trends like increasing product and service variability or faster time to market, and to ensure business IT alignment. Along this trend, a new generation of information systems has emerged—so-called process-aware information systems (PAIS), like workflow management systems, case handling tools, and service orchestration engines. With this book, Reichert and Weber address these flexibility needs and provide an overview of PAIS with a strong focus on methods and technologies fostering flexibility for all phases of the process lifecycle (i.e., modeling, configuration, execution and evolution). Their presentation is divided into six parts. Part I starts with an introduction of fundamental PAIS concepts and establishes the context of process flexibility in the light of practical scenarios. Part II focuses on flexibility support for pre-specified processes, the currently predominant paradigm in the field of business process management (BPM). Part III details flexibility support for loosely specified processes, which only partially specify the process model at build-time, while decisions regarding the exact specification of certain model parts are deferred to the run-time. Part IV deals with user- and data-driven processes, which aim at a tight integration of processes and data, and hence enable an increased flexibility compared to traditional PAIS. Part V introduces existing technologies and systems for the realization of a flexible PAIS. Finally, Part VI summarizes the main ideas of this book and gives an outlook on advanced flexibility issues. The attached pdf file gives a preview on Chapter 3 of the book which explains the book's overall structure

Lightweight Process Support with Spreadsheet-Driven Processes: A Case Study in the Finance Domain

The use of process management technology constitutes a salient factor for a multitude of business domains as it particularly addresses the flexibility demands of the digital enterprise. Still, spreadsheet applications are more likely to be used in many scenarios in which process management technology appears to be a more appropriate solution. Especially in the context of human-centric and knowledge-intensive processes, spreadsheets are widely used, even if more business-tailored applications exist. For example, financial service providers, like banks or insurers, prefer spreadsheet applications for accomplishing their daily business. However, this kind of usage reveals drawbacks when working collaboratively based on the same spreadsheet document. To remedy these drawbacks, we suggest the use of spreadsheet-driven processes, which shall combine the advantages of traditional process management technology with the ones of spreadsheets. Using a sophisticated scenario from the financial domain, this paper shows how spreadsheet-driven processes improve collaborative work, as required in the context of business processes, significantly. Moreover, a proof-of-concept prototype is presented to evaluate the approach in practice. Altogether, first results indicate that spreadsheet-driven processes may be a promising technical solution for everyday business involving human resources

Process Change Patterns: Recent Research, Use Cases, Research Directions

In previous work, we introduced change patterns to foster a systematic comparison of process-aware information systems with respect to change support. This paper revisits change patterns and shows how our research activities have evolved. Further, it presents characteristic use cases and gives insights into current research directions

The ADEPT Project: A Decade of Research and Development for Robust and Flexible Process Support - Challenges and Achievements

This paper gives insights into the ADEPT project. Its target was to develop a next generation process management technology, which is by orders of magnitudes more powerful and flexible than contemporary process management systems. The ADEPT technology should provide advanced features and properties within one system, which seem to exclude each other, but which are required for the support of a broad spectrum of processes: ease-of-use for end users and system developers, high flexibility through the support of non-trivial ad-hoc deviations at the process instance level, quick implementation of process changes through process schema evolution, and correctness guarantees enabling robust execution of implemented processes. This paper describes the background and the real-world cases which motivated our research. It further explains the technological challenges we faced, describes the solutions we elaborated, and discusses the current status of the ADEPT project
