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 – Oktay Turetken: The Understandability of Business Process Models: The Effect of Modularity Representation …

Speaker: Oktay Turetken

Title: The Understandability of Business Process Models: The Effect of Modularity Representation, Presentation Medium, and BP Modelling Competencies

Abstract: Many factors influence the creation of understandable business process models for an appropriate audience. Understandability of process models becomes critical particularly when a process is complex and its model is large in structure. Using modularization to represent such models hierarchically (e.g. using sub-processes) is considered to contribute to the understandability of these models. To investigate this assumption, we conducted two experiments that involved 2 large-scale real-life business process models that were modeled using BPMN. Each process was modelled in 3 modularity forms: fully-flattened, flattened where activities are clustered using BPMN groups, and modularized using separately viewed BPMN sub-processes. The main objective is to investigate if and how different forms of modularity representation in BPMN collaboration diagrams influence the understandability of process models. In addition to the modularity representation, we also looked into other factors that potentially influence model comprehension. These include the presentation medium (paper vs. computer), and personal factors, such as model reader’s level of BPM experience and competency. The first experiment involved 60 business practitioners from a large organization, while 140 graduate students participated in the second experiment. The results of the experiments indicate that process models in the form of BPMN collaboration diagrams are best understood by people with relatively high BPM competencies, and when represented in ‘flattened’ forms (with or without the use of groups) and in ‘paper’ format.

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

Colloquium IS Rodrigo Gonçalves: Obtaining, analyzing and manipulating traffic data for a vehicle routing application

Speaker:
Rodrigo Gonçalves

Title:
Obtaining, analyzing and manipulating traffic data for a vehicle routing application.

Abstract:
Vehicle routing problem concerns the service of a logistics company. How things are delivered from one or more depots in a given set of vehicles which move on a given road network to a set of customers. The solution is a set of routes which minimizes global transportation costs. Solutions are obtained based on known characteristics of routes such as travel times or distances between customers. Even though distances are fixed, travel times fluctuate. They are heavily dependent on punctual occurrences, like weather related events or traffic accidents, but also on the period of the year, month and day. In this talk, I will discuss how travel time data was obtained from a TomTom API, how we overcame API limitations by manipulating data and I’ll provide an analysis of how travel time changes with the period of the year, month and day.

Colloquium Jos Trienekens, april: “Information Quality, framing an evolving information management concept”

Speaker:
Jos Trienekens

Title:
Information Quality, framing an evolving information management concept

Abstract:
Over the years information quality has been subject to many Ph.D research and MSc. projects in the information/software management research group of our capacity group Information Systems.

This presentation will position the information quality concept in a three-level framework, and will clarify characteristics of various research projects (in our group). On each level the focus areas of specification, metrication, standardisation and continuous improvement will be discussed.

In recent years the concept of information quality has evolved towards an IT Governance subject in inter-organisational networks.  Some examples of this evolution will be presented with reference to current Ph.D projects in our research group.

Rik Eshuis

Title:
Supporting knowledge-intensive processes with case management

Abstract:
In recent years, case management has emerged as an approach to support knowledge workers in performing and coordinating business processes. These knowledge-intensive processes are semi-structured and can easily change. Case data and business rules determine the actual flow of work in a knowledge-intensive process. In this talk, I will discuss when to apply case management, how to design knowledge-intensive processes for case management, and how to manage changes in these knowledge-intensive processes.
