Now the Master Programme in Health Informatics with Karolinska Institute has started.

Today the education programme of Enterprise Systems are visiting IBM and the Innov8 workshop. 30+ students and a few teachers get hands-on experience with IBMs tools for business process management. We get the opportunity to simulate different business processes, such as traffic planning, customer service and supply chain. We also get the opportunity to test the IBM Websphere tool to design, implement and evaluate business processes in a SOA environment. Although the ES programme already have courses in BPM, the Innov8 workshop broadens our knowledge about BPM and BPM tools. It also deepens the relationship between IBM and DSV in the area of service science.

I nya numret av CIO Sweden (Oktober 2010) diskuterar jag och Håkan Enquist från handelshögskolan i Göteborg nya affärsmodeller för tjänstebaserade affärssystem. Artikeln är baserad på fallstudier från 18 organisationer och företag verksamma inom affärssystem på den svenska marknaden. Vi presenterar bland annat två mönster av affärsmodeller: niche och holistic. Artikeln baseras på resultat från Vinnova-projektet “Tjänstebaserade affärsmodeller för affärssystem”.

We are happy to announce that the paper “Design of an Open Social E-Service for Assisted Living” was awarded “most promising practical concept” at the EGOV2010 conference in Lausanne Switzerland. The paper was written by myself, Gustaf Juell-Skielse, and Petia Wohed. The EGOV conference focuses on issues related to design, implementation and evaluation of e-Government. This was the ninth conference in the series and attracted almost 150 researchers presenting about 100 papers. Our paper presented some of the results from the Open Social Services project at Järfälla municipality financed by Vinnova.

The site shows some examples of how business models can be applied in health care. Each business model is described in terms of problems that they solve, existing examples of their use, and a short discussion of drawback and benefits with the model. Drawback and benefits of each model are described by linking to a set of values derived from existing quality frameworks.

The site is developed as a part of the VIPPA project.

As members of The Swedish Research School of Management and IT (MIT) Edephonce Nfuka and I have participated between 5 to 7th October 2010 to the MIT seminar at Uppsala University. Here we have presented a research paper named “The effect of critical success factors on IT governance performance in the public sector organizations from a developing country: A case of Tanzania”. The paper has well been received and the comments we have got from the participants to this seminar will due to an improvement of our paper that has been targeted to be submitted for publication to a journal. The MIT seminar from this year was also an opportunity to attend different paper presentations and make constructive comments to the authors for the improvement of their papers. Moreover in the MIT seminar from Uppsala University we have attended three interesting lectures done by Professor John Kimberly from The Wharton School, University of Pennsylvania.

A paper evaluating the CM3 Emergency Problem Management process using a scenario-based methodology have been accepted to the The Working Conference on Reverse Engineering (WCRE) 2010 in Boston.

WCRE is a conference focusing on reverse engineering and extracting information from software and systems. Using scenarios is an effective method to communicate process functionality which is useful in software reenginering.The paper describes software maintenance processes and IT management considerations in case of emergencies and organisational crisis situations caused by malfunctioning software.

The paper was a joint effort by Dr. Mira Kajko-Mattson, Emil Hammargren and me, Joakim Snygg.

After the Best paper award at the ER 2009 conference, we got invitation to write a journal article on Anchor Modeling. The title of the new article is “Anchor Modeling – Agile Information Modeling in Evolving Data Enviornmnets”. The authors are Lars Rönnbäck (Resight), Olle Regardt (Teracom), Maria Bergholtz (DSV), Paul Johannesson (DSV) and I. The article has now been accepted for publication in the journal Data and Knowledge Engineering (DKE, Elsevier). A preprint of it can be found here.

Abstract: Maintaining and evolving data warehouses is a complex, error prone, and time consuming activity. The main reason for this state of aairs is that the environment of a data warehouse is in constant change, while the
warehouse itself needs to provide a stable and consistent interface to information spanning extended periods
of time. In this article, we propose an agile information modeling technique, called Anchor Modeling, that
oers non-destructive extensibility mechanisms, thereby enabling robust and exible management of changes.
A key benet of Anchor Modeling is that changes in a data warehouse environment only require extensions,
not modications, to the data warehouse. Such changes, therefore, do not require immediate modications of
existing applications, since all previous versions of the database schema are available as subsets of the current
schema. Anchor Modeling decouples the evolution and application of a database, which when building a
data warehouse enables shrinking of the initial project scope. While data models were previously made
to capture every facet of a domain in a single phase of development, in Anchor Modeling fragments can
be iteratively modeled and applied. We provide a formal and technology independent denition of anchor
models and show how anchor models can be realized as relational databases together with examples of
schema evolution. We also investigate performance through a number of lab experiments, which indicate that
under certain conditions anchor databases perform substantially better than databases constructed using
traditional modeling techniques.
