Colloquium IS (June 2, 2017) – ISO 20000 adoption challenges – A Delphi study

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

June 2, 2017, 12:30 – 13:30 (Paviljoen K.16).

Speaker: Barış Özkan

Title: ISO 20000 adoption challenges – A Delphi study

Abstract:
The traditional resource and technology centered relationship between IT organizations and its clients is undergoing a transformation worldwide. On one end, both internal users and external clients demand cost-effective and high performance IT services which can be aligned to their changing business goals, needs and environments instantly. On the other end, IT organizations are shifting their focus from technology management to service management striving to deliver IT value by provision of IT services and to maintain their complex IT infrastructures at the same time. IT organizations are leaving their monopolistic role in the provision of IT services and the relationship is evolving into customer/provider relationships in which customers’ role change from service recipients to value co-creating stakeholders in service design and innovation.
Information technology service management (ITSM) has developed and expanded as a discipline that aims the systemic study of IT service systems throughout service life cycles and from strategic to operational levels. Various ITSM frameworks, practices and models have been proposed for establishing ITSM systems such as ITIL, Microsoft MOF, CMMI-SVC. ISO/IEC 20000 is the first international standard which sets out formal requirements and related guidance for an ITSM system whereby ITSM processes of an organization can be established and assessed. ISO 20000 has achieved an international recognition, yet there is a high potential and market push for ITSM certification at an international level.
In this talk after a brief introduction to ITSM and ISO 20000, an ongoing Delphi study that explores and investigates the challenges of ISO 20000 adoption will be explained and then preliminary results will be discussed.

Colloquium IS (April 7, 2017) – Pieter Van Gorp: Towards Unified Health Gamification

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

April 7, 2017, 12:30 – 13:30 (Paviljoen K.16).

Speaker: Pieter Van Gorp

Title: Towards Unified Health Gamification

Abstract: There is a multitude of mobile Health (mHealth) applications that aim to solve societal health problems by stimulating specific types of physical activities via gamification. However, physical healthactivities cover just one of the three World Health Organization (WHO) dimensions of health. This talk introduces the novel notion of Unified Health Gamification (UHG), which covers besides physical health also social and cognitive health and well-being. Instead of rewarding separate activities in the three WHO dimensions using different mHealth competitions, UHG combines the scores for such activities on unified leaderboards and lets people interact in social circles beyond personal interests. This approach is promising in corporate environments since UHG can connect the employees with intrinsic motivation for physical health with those who have quite different interests. In this talk, we motivate the relevance of UHG and we showcase GameBus, a UHG prototype that we have applied successfully in various case studies in companies and municipalities. Preliminary results demonstrate significant improvements in self reported mental well-being.  The talk is scheduled while two larger scale pilots are ongoing so we will share recents insights too. We also foresee time to discuss business model considerations as well as technical aspects such as the GameBus REST APIs, the data model, etc.

Bio: Pieter Van Gorp has obtained his Ph.D. degree in Software Engineering at the University of Antwerp. Since 2008, he is an assistant professor in Information Systems at Eindhoven University of Technology. His research focuses on personal health data as an economic asset. In 2016, he has launched GameBus, a data-driven platform that rewards you for performing healthy activities in a social manner. He had previously designed an execution platform for securely analyzing Personal Health Records in the cloud. Van Gorp is also known for his work on reproducible research and model transformations for UML, BPMN and Petri-Nets.

Colloquium IS (March 3, 2017) – Remco Dijkman: Linguistic Summarization of Event Logs

Dear all,

We are pleased to invite you to our next Colloquium IS that will take place on Friday,

March 3, 2017, 12:30 – 13:30 (Paviljoen K.16).

Speaker: Remco Dijkman

Title: Linguistic Summarization of Event Logs

Abstract: The amount of data that is generated during the execution of a business process is growing. As a consequence it is increasingly hard to extract useful information from the large amount of data that is produced. Linguistic summarization helps to point business analysts in the direction of useful information, by verbalizing interesting patterns that exist in the data. In previous work we showed how linguistic summarization can be used to automatically generate diagnostic statements about event logs, such as `for most cases that contained the sequence ABC, the throughput time was long’. However, we also showed that our technique produced too many of these statements to be useful in a practical setting. Therefore we present a novel technique for linguistic summarization of event logs, which generates linguistic summaries that are concise enough to be used in a practical setting, while at the same time enriching the summaries that are produced by also enabling conjunctive statements. The improved technique is based on pruning and clustering of linguistic summaries. We show that it can be used to reduce the number of summary statements 80-100% compared to previous work. In a survey among 51 practitioners, we found that practitioners consider linguistic summarization useful and easy to use and intend to use it if it were commercially available.

 

Colloquium IS Rob Kusters: Decision Criteria for Software Component Sourcing Steps towards a Framework

Speaker:
Rob Kusters

Title:
Decision Criteria for Software Component Sourcing Steps towards a Framework

Abstract:
Software developing organizations nowadays have a wide choice when it comes to sourcing software components. This choice ranges from developing or adapting in-house developed components via buying closed source components to utilizing open source components. This study seeks to determine criteria that software developers can use to make this choice. Answering this question will result in a list of criteria that can, after further validation, be used to develop structured decision support in this type of decision. A first step is a literature search resulting in an initial list. Since the literature used was not specifically targeted at the question at hand, it was decided to separately conduct interviews to obtain an independently derived list of criteria. In a second part of the interview the respondents were confronted with the list resulting from literature. Together this resulted in a preliminary proposal for decision criteria for software sourcing

Summary

During the execution of an inter-organizational business-to-business (B2B) collaboration, a collaborating party may drop out for technical reasons or for business reasons. In such a case, the leaving party must be replaced, at runtime, by a new party. Ideally, the new party can pick up where the old party left off.

Currently, algorithms exist that can help with the runtime selection of the new party in order to incorporate it in the collaboration. Also, several studies have investigated the theoretical foundations of dynamic business process changes within a single enterprise. However, very few attempts have been made which can help a new party in a collaboration to pick up where the old party left off. Designing such techniques constitutes a challenge due to each party’s autonomy and to privacy policies that emerge in the context of a collaboration.

This PhD study aims to address this challenge by providing an overview of the components, algorithms, operations and techniques that are necessary to enable a party in a collaboration to be replaced by another party at runtime. Accordingly, this study consists of the following three research activities.

Firstly, it presents a descriptive reference architecture for Business Process Management Systems (BPMS) that facilitates switching parties in inter-organizational collaborations. This reference architecture, called BPMS-RA, has been designed based on a systematic literature survey of existing BPMS architectures. The main purpose of the development of BPMS-RA is twofold: (i) it can be employed as an architectural template for developing a new BPMS by offering two distinct levels of aggregation for the components that comprise a BPMS architecture, and (ii) it enables the analysis and comparison of existing BPMS in terms of their functionalities.

Secondly, it introduces a strategy for adapting an inter-organizational collaboration when a global view on the collaboration exists. In this strategy we assume that it is possible to have a central party, called the global controller, that can observe all communication and be the intermediary between all collaborating parties when one party is replaced by another. In this case there is also a model that describes all communications, which is called the choreography model. This research contributes to the body of knowledge by proposing a set of algorithms, operations and techniques (such as rollback and compensation) that facilitate the party switch in the case where a global controller and a choreography model exist.

Finally, it describes a strategy for adapting an inter-organizational collaboration when a global view on the collaboration does not exist. In this strategy, we assume that there is no global controller in a collaboration and no choreography model of the collaboration. The main challenge in this case is to capture the choreography model by relating the past communications among the collaborating parties that belong to the same thread of collaboration. This challenge is also known as the correlation challenge. This study addresses this challenge by introducing a new process discovery algorithm, called the correlation miner, that facilitates discovery when events (i.e., messages) are not associated with a case identifier.

In order to demonstrate the feasibility of these studies, we have developed prototype tools that implement our solutions and we evaluated them in a practical setting. Additional experiments were performed on both synthetic and real-world process models in order to determine the extent to which our proposed solutions are applicable.

Summary

Information Governance in Service-Oriented Business Networking

Competition in current business environments forces organizations to focus on their core competencies and outsource other activities. Organizations focusing on their core competencies collaborate with globally distributed business parties to provide products and services for customers. This highlights the importance of business networking for achieving competitive advantages. In this way, nowadays competition is between business networks (BNs) rather than between single organizations.

On the other hand, customers’ empowerment in globalized markets necessitates service orientation in BNs. Service orientation in BNs points out deep interactions with customers for value co-creation as well as dynamic and agile collaboration with suppliers to deliver mass-customized products and services. In this way, a service-oriented business network (SBN) is described as a collaborative network of independent parties within a market that co-create mass-customized packages of products and services in the form of integrated solutions.

Service orientation in BNs requires sensing of environmental changes (e.g. customer needs) and responding to these needs rapidly through agile orchestration of resources distributed among parties. Orchestration of distributed resources within a BN is realized by networked business processes. Service orientation in BNs highlights information-intensive networked business processes. The information-intensity implies dynamic evolution of networked business processes in order to respond to environmental requirements. The property of information-intensity is further increased by emerging paradigms like big data, cloud computing, and internet of things that enable to generate, store, access, and use globally distributed information. However, this situation results in emerging issues such as unsecured information access and low quality information products. These issues strongly threaten performance of BNs. So, they need to be recognized and countered by information governance (IG) mechanisms in an appropriate way. IG in the context of BNs can be characterized as a holistic approach to enable high quality and secure information exchanges among collaborating parties.

This dissertation concentrates on IG in SBNs. To do so, the dissertation is organized within the three main parts. The first part of the thesis characterizes SBNs within an integrated framework in the form of three-two dimensional matrices. The applicability and usefulness of the developed framework to characterize service orientation in real-life BNs is evaluated by a multiple-case study.

The second part of the dissertation concentrates on the identification of the IG issues resulting from service orientation in BNs. To do so, a systematic literature review is conducted that results in the identification of the 28 IG issues. These issues are categorized within information quality, information security, and metadata domains. The practical relevance of the theoretically identified IG issues is evaluated by a case study.

The third part of the dissertation describes synthesizing an architectural solution to deal with the identified IG issues. The designed architecture specifies components that support governing information assets that are exchanged to manage dynamic networked business processes in SBNs.

Title: Fuzzy Fingerprints: Identification and classification in Big data using top-k values

Information about the event is as follows:

Abstract: Fuzzy Fingerprints are a recently introduced technique inspired by the fact that many types of data studied in the physical and social sciences can be approximated with a Zipfian distribution. I.e., the frequency of an item is inversely proportional to its rank in the frequency table. Fuzzy Fingerprints efficiently use the implicit information contained in top-k most frequent data values to perform identification in large datasets. The term “fingerprint” is used in the sense that fingerprints are unique, and are usually left unintentionally, allowing us to identify their “owners”. The fingerprint concept can be extended from single users to categories, topics or classes, allowing us to perform tasks such as classification and recommendation.

In this talk I will approach the ideas behind Fuzzy Fingerprints and show case studies and applications involving: identification of anonymous users based on their phone and web usage habits; text author identification based on their writing habits; classification and identification in social data (e.g. detecting tweets related to a given trending topic); classification based on medical text data; movie recommendation; etc.

This event is technically co-sponsored by the Benelux Chapter of IEEE
Computational Intelligence Society.
