Groupe Bull SA announced last week that it intends to boost its systems integration revenues to between 10% and 15% of its total business by 1995 from around 5% in 1991. Jacques Weber, director of Bull’s Systems Integration and Services, says that the rate of growth in integration is considerably stronger in Europe than in the US, and that Bull is ranked tenth in the world, fifth in Europe. The company has systems integration units in the US, UK, Italy, France and Scandinavia, where it bought 75% of Diab Data AB of Stockholm, Sweden last year.
