Agilität in nicht-agilen Unternehmen

Julia Fischer, Christian Schönberg, Thomas Breisig, Andreas Winter
2018 Vorgehensmodelle - Anspruch und Wirklichkeit  
Agile Methoden wie Scrum sind seit einiger Zeit in der Softwareentwicklung etabliert. Dies kann in Unternehmen, die nicht ihre gesamte Organisation auf Agilität umstellen wollen oder können, zu Konflikten zwischen den agilen und den nicht-agilen Unternehmensbereichen führen. Relevant ist dies insbesondere für Unternehmen, welche die Vorteile der Agilität nutzen wollen, aber gleichzeitig strengen regulatorischen oder organisatorischen Vorschriften unterliegen. In diesem Beitrag wird anhand
more » ... tischer und praktischer Untersuchungen exemplarisch für Scrum gezeigt, an welchen Stellen diese Konflikte entstehen können. Zur Entschärfung der Konflikte werden Handlungsempfehlungen vorgestellt, so dass agile Vorgehensmodelle erfolgreich auch in Unternehmen mit klassischer Linienorganisation und Projektmanagement eingesetzt werden können.

Visualizing B2Bi choreographies

Andreas Schonberger
2011 2011 IEEE International Conference on Service-Oriented Computing and Applications (SOCA)  
The implementation of cross-organizational processes in the context of Business-to-Business integration (B2Bi) requires extensive communication between all interacting parties and adequate solutions for the integration of existing IT systems. In the SOA domain, choreography languages have been put forward for the specification of the publicly visible message exchange sequences of interacting parties. Choreography models serve as basis for communication between stakeholders and as reference for
more » ... ligning business services which is a core SOA concept. However, visual choreography modeling guidelines that are both, tailored to B2Bi and unambiguous in semantics, have not been proposed so far. This paper fills in this gap by showing how BPMN choreography notation can be used to represent socalled B2Bi choreographies with unambiguous semantics. The work has been validated by a series of real-world use cases of the RosettaNet community and has been accepted by the RosettaNet Message Control and Choreography team as core part of a RosettaNet standard.

A liquid-crystalline hexa-adduct of [60]fullerene

Thierry Chuard, Robert Deschenaux, Andreas Hirsch, Hubert Schönberger
1999 Chemical Communications  
A hexa-adduct of [60]fullerene was synthesized by addition of a mesomorphic twin cyanobiphenyl malonate derivative to C 60 ; whereas the malonate derivative gave a monotropic nematic phase, the fullerene hexa-adduct showed an enantiotropic smectic A phase. The recent discovery of [60]fullerene-containing thermotropic liquid crystals 1 is of interest considering the current activity devoted to the search of fullerene-based new materials. 2 The unique magnetic, optical and redox properties of
more » ... fullerene (C 60 ) and its derivatives motivated these studies. 3 The above liquid-crystalline mono-adduct C 60 derivatives 1 were prepared by functionalizing the C 60 core with a mesomorphic malonate framework containing cholesterol as a mesomorphic promoter. These materials showed smectic A phases. [60]Fullerene offers multiple possibilities for the design of functionalized derivatives. 4 To further explore the capability of C 60 to give rise to mesomorphic structures, we focussed on hexa-adducts. Observation of liquid-crystalline properties from such an addition pattern would be of interest to rationalize and better understand the structure-liquid-crystalline properties relationship for this new family of liquid crystals. We describe herein the synthesis, characterization and thermal behavior of the fullerene hexa-adduct 1, which represents a novel example of a mesomorphic C 60 derivative, and of the fullerene mono-adduct 2. Compounds 1 † and 2 † were prepared by addition of the malonate derivative 3 † to C 60 in 9 and 43% yield, respectively. The thermal properties of 3 are also reported. The liquid-crystalline phases ‡ and thermal properties § of 1-3 were investigated by differential scanning calorimetry (DSC, rate: 10 °C min 21 under N 2 ) and polarized optical microscopy (POM). Malonate derivative 3 gave a monotropic nematic phase (I ? N: 87 °C, DH = 2.7 kJ mol 21 ; N ? Cr: 57 °C, DH = 50 kJ mol 21 ; peak transitions) ¶ which was identified by POM from the observation of typical schlieren and homeotropic textures. Mono-adduct 2 was found to be non-mesomorphic. The only event which was observed was melting of the sample into the isotropic fluid (Cr ? I: 114 °C, DH = 31 kJ mol 21 ; peak transition; first heating run). Hexa-adduct 1 gave interesting results. By DSC, an endotherm was detected at 133 °C (DH = 42 kJ mol 21 , i.e. 3.5 kJ mol 21 per cyanobiphenyl group; onset transition) during the first heating run. Reversibility of this transition was observed during the cooling scan. The formation of a liquid-crystalline phase was observed by POM between about 80 and 133 °C. Slow cooling of the sample from the isotropic fluid revealed the formation of focal-conic and homeotropic textures typical of the smectic A phase (Fig. 1) . The transition recorded by DSC at 133 °C corresponded to the clearing point. The fact that no melting point was detected by DSC is, most likely, a consequence of the amorphous character of 1 in the solid state (1 was recovered by evaporation of the solvents after preparative HPLC †); no glass transition was observed by DSC. The bulky C 60 unit acts as a spacer separating the molecules from each other: for mono-adduct 2, the intermolecular interactions are too weak to generate mesomorphism. The influence of C 60 can be thwarted by using malonate derivatives possessing a higher liquid-crystalline character than that of 3, as we have already demonstrated. 1 The liquid-crystalline behavior of 1 emphasizes the role played by C 60 in the case of hexa-addition: assembling twelve cyanobiphenyl units around a focal point generates the required structural anisotropy and intermolecular interactions for mesomorphism to occur. It is noteworthy that polyaddition can be used for the preparation of fullerene-containing thermotropic liquid crystals from addends with low liquid-crystalline tendencies. Observation of a smectic A phase for 1 indicates that the cyanobiphenyl units are not oriented radially around the C 60 but Fig. 1 Thermal optical micrograph of the focal-conic fan texture displayed by 1 in the smectic A phase upon cooling the sample (0.01 °C min 21 ) from the isotropic liquid to 129 °C.

Towards Executing ebBP-Reg B2Bi Choreographies

Andreas Schonberger, Guido Wirtz
2010 2010 IEEE 12th Conference on Commerce and Enterprise Computing  
Applying choreography and orchestration technology to Business-to-Business integration (B2Bi) scenarios has become a popular technique for very good reasons. Choreography descriptions can be used to capture B2Bi scenarios from a global and abstract perspective while orchestrations then can be used to specify the local implementation of each integration partner. ebXML BPSS (ebBP) is a prominent B2Bi choreography standard with very helpful domain-specific concepts, but clear guidelines for
more » ... g executable choreographies are missing. In order to create ebBP models that are both adequate and executable, expressiveness, comprehensibility and standard-conformance have to be weighed up. In this paper, we introduce ebBP-Reg as an ebBP modeling flavor that is designed such that ebBP-Reg choreographies are executable as WS-BPEL orchestrations. At the same time, ebBP-Reg models strictly conform to the ebBP standard and support concurrency and decomposition. We characterize syntactic validity of ebBP-Reg models by means of language production rules and show how instances of ebBP-Reg can be implemented using WS-BPEL.

Using Variable Communication Technologies for Realizing Business Collaborations

Andreas Schonberger, Guido Wirtz
2009 2009 World Conference on Services - II  
In today's business world, enterprises are not only using Web Services for implementing B2Bi. Instead, AS2 for realizing Internet based EDI, ebXML Messaging and even SMTP and FTP are used for exchanging business documents. Harmonizing B2Bi communication technology in a way that solely uses Web Services is barely an option for large enterprises as this would result in losing investments in existing IT systems. Moreover, forcing a specific communication technology upon all business partners is
more » ... ther intended nor realistic in practice. At the same time, existing business document exchanges frequently only implement B2Bi scenarios partly. This paper focuses on a method for composing existing and new business document exchanges without replacing communication technology already in use. First, ebXML BPSS is proposed for describing the choreography of business document exchanges in a technology agnostic way. Second, ebXML CPPA is used to define messaging characteristics at the level of ebBP BusinessTransactions. Third, an integration architecture for performing ebXML BPSS choreographies using BPEL processes that execute each integration partner's message exchanges is proposed. These BPEL processes assume Web service wrappers for reusing the functionality of messaging systems that are responsible for performing the actual business document exchanges and for providing sufficient status information to the caller. Different messaging systems then can be used for incorporating variable communication technologies in business collaborations.

Semantic Visual Localization

Johannes L. Schonberger, Marc Pollefeys, Andreas Geiger, Torsten Sattler
2018 2018 IEEE/CVF Conference on Computer Vision and Pattern Recognition  
Robust visual localization under a wide range of viewing conditions is a fundamental problem in computer vision. Handling the difficult cases of this problem is not only very challenging but also of high practical relevance, e.g., in the context of life-long localization for augmented reality or autonomous robots. In this paper, we propose a novel approach based on a joint 3D geometric and semantic understanding of the world, enabling it to succeed under conditions where previous approaches

The resulting 3D descriptors are robust to missing observations by encoding high-level 3D geometric and semantic information. Experiments on several challenging large-scale localization datasets demonstrate reliable localization under extreme viewpoint, illumination, and geometry changes.

Edit Distance-Based Pattern Support Assessment of Orchestration Languages [chapter]

Jörg Lenhard, Andreas Schönberger, Guido Wirtz
2011 Lecture Notes in Computer Science  
Orchestration languages are of paramount importance when implementing business processes based on services. Several languages for specifying Web Services-based orchestrations are available today. Examples are the Web Services Business Process Execution Language or Windows Workflow. Patterns for process-aware information systems have frequently been used to assess such languages. Various studies discuss the degree of support such languages provide for certain sets of patterns. However, the
more » ... ional trivalent support measure is limited in terms of granularity and selectivity. This paper proposes an edit distance complexity measure that allows to overcome these issues. The applicability of this measure is demonstrated by an analysis of several orchestration languages using four different pattern catalogs.

A Model-Driven Approach for Monitoring ebBP BusinessTransactions

Simon Harrer, Andreas Schönberger, Guido Wirtz
2011 2011 IEEE World Congress on Services  
ebXML BPSS (ebBP) is well-suited to specify Business-to-Business (B2B) interactions as choreographies of so-called BusinessTransactions. Web Services and WS-BPEL as dedicated interface technologies then can be used to provide the implementation of such choreographies. Tracking and ensuring the progress of choreographies calls for monitoring facilities that require gathering information from log data of the runtime systems that execute WS-BPEL processes. However, the information provided by
more » ... EL monitoring tools is fine-granular so that information about the actual progress in terms of choreographies must be extracted manually. Our approach streamlines the monitoring of ebBP Busi-nessTransactions leveraging model-driven engineering. First, hierarchical communicating automata are used to formalize BusinessTransactions. Second, WS-BPEL implementations of these automata are derived such that monitoring events are propagated to a monitoring service whenever a transition of the underlying automaton fires. Third, the monitoring service translates the monitoring events into choreography progress by visually highlighting the active and visited states within the hierarchical automata. It thus presents a user-friendly model that abstracts from the details of the implementing WS-BPEL processes. This makes tracking the current state of choreographies accessible to business users.

Learning Priors for Semantic 3D Reconstruction [chapter]

Ian Cherabier, Johannes L. Schönberger, Martin R. Oswald, Marc Pollefeys, Andreas Geiger
2018 Lecture Notes in Computer Science  
We present a novel semantic 3D reconstruction framework which embeds variational regularization into a neural network. Our network performs a fixed number of unrolled multi-scale optimization iterations with shared interaction weights. In contrast to existing variational methods for semantic 3D reconstruction, our model is end-to-end trainable and captures more complex dependencies between the semantic labels and the 3D geometry. Compared to previous learning-based approaches to 3D
more » ... n, we integrate powerful long-range dependencies using variational coarse-to-fine optimization. As a result, our network architecture requires only a moderate number of parameters while keeping a high level of expressiveness which enables learning from very little data. Experiments on real and synthetic datasets demonstrate that our network achieves higher accuracy compared to a purely variational approach while at the same time requiring two orders of magnitude less iterations to converge. Moreover, our approach handles ten times more semantic class labels using the same computational resources. * These authors share first authorship.

Do We Need a Refined Choreography Notion?

Andreas Schönberger
2011 Central-European Workshop on Services and their Composition  
Since the term choreography for capturing the publicly observable message exchanges between integration partners was coined, choreography technology evolved significantly. Today, the diversity of choreography languages is high. Up to now, choreography languages have been categorized by distinguishing between implementation specific and implementation independent choreographies as well as interaction and interconnection choreographies. In this work, we review important characteristics of
more » ... aphy technologies to find out whether a refined choreography notion is needed. The fact that choreography classes that are almost orthogonal to existing categorizations as well as several selective choreography characteristics can be identified suggests this need.
