SISA – Svenska informationssystemsakademin

Idag hölls det första årsmötet för SISA – Svenska informationssytemsakademin. SISA är en förening för svenska universitet, högskolor och forskningsinstitutioner som arbetar med informationssystem. Informationssystem “är det vetenskapliga ämne som utvecklar kunskap om människors design och bruk av IT i individuella, organisatoriska och samhälleliga sammanhang. Inom denna ram finns vid svenska universitet och högskolor ett antal olika inriktningar.” Föreningen syftar till att samordna och uppmärksamma forskning och utbildning inom informationssystem.

A Presentation on Social Media

Last week I gave an invited presentation on social media at KTH X, which is the alumni association at KTH. The presentation covered the basics of social media and raised questions about the use of social media in work, the future of personal integrity, the emerging topology of Internet and many other issues. About 40 people had come to listen and particpate in the discussion.

Seminar on Business Process Management and Enterprise Architecture

Jens Ohlsson from IDS Scheer gave a lunch seminar on Business Process Management and Enterprise Architecture. Jens discussed the differences between an industrial and an academic view on these topics. He also presented the view of IDS Scheer on the future development in these areas. Thanks Jens for a nice presentation and a lively discussion!

Ambjörn Naeve on Provocative Modelling

Ambjörn Naeve held a seminar on Provocative Modelling on 12 February. Ambjörn is presently a guest lecturer at DSV. Here follows Ambjörn’s summary and documentation of the seminar.

Provocative Modeling is a term that I came up with a while ago to describe models that provoke “engagement by disagreement” by exposing controversial ideas, beliefs and assumptions – often called prejudice. Since we can process only up to about 30 bits per second in our conscious mind, while we are at the same time receiving about 3 million bits per second through our senses, this information needs to be compressed about 100.000 times before we can deal with it on the conscious level. Hence, without pre-judging there can be no effective judging, and therefore it is not an option to be without prejudice. The question is only which prejudices you have. Also, by exposing your underlying beliefs and assumptions related to an issue, they become visible and therefore amenable to change. This is what Peter Senge calls Mental Modeling (, which is one of the five disciplines of organizational learning ( my talk I will display (what I think is) some of my more “provocative models” on terrorism, religion, gender, education, economics, and promotion strategies within a large organization. These models have been developed in our modeling tool Conzilla ( and the links to the presented models will be made available for the participants.

Göran Goldkuhl guest professor

Göran Goldkuhl is guest professor since 1 Jan 2010. From Görans’s profile:

I am guest professor (10%) in information systems since Jan 1 2010. This is actually a comeback to both DSV and SYSLAB. I was employed at DSV 1973-1982. I got my PhD 1980 on information models. Since I left DSV 1982 I have been assistant professor at Göteborg university (1982-86), associate professor at Linköping university (1986-1996), professor at Jönköping International Business School (1996-2008) and professor at Linköping university (1999-). I am the research director of research group VITS since 1991. You can read more about my research career from early days at Stockholm university (ISAC group) via SYSLAB & research group HUMOR (in Göteborg to research group VITS (in Linköping and other universities) at Continue reading

Conference on the History of Nordic Computing

The first and second conferences on the history of Nordic computing, organized in Trondheim (2003) and Turku (2007) respectively, were very successful and acquired a great deal of interest from information and communication technology (ICT) professionals and academics as well as from historians of technology. Therefore, these conferences will now be followed by a third one, which will take place in Stockholm, October 2010.

NESSI National Platforms Meeting

Today the NESSI National Platforms had a meeting to further develop their cooperation. Europe will in the coming years face a multitude of challenges caused by profound changes in social attitudes, economic conditions, global relationships, and the business environment. The overall goal of the NESSI National Platforms is to promote the development and application of service and ICT technologies for addressing these challenges.

Next to the societal and business needs for services delivered through ICT, there is the practical need within Europe to know what is happening in these fields in the various countries. At this moment NESSI, and the European Commission, lack an overview of what is happening in the field of ICT and services. The national platforms are closer to the source of information and in that way they are more able to provide the information needed. This is one of the main motives to set up a network of platforms. The platforms can learn from each other: best and worst practices can be exchanged. Which government projects succeeded, which failed? What is the state of E-health, and E-Government in the various countries, which countries are ahead and which countries need to improve ICT services? Working together will increase knowledge management in this field considerably.

Eva Söderström. Petia Wohed and I are in the process of setting up a Swedish NESSI platform.
