Companies that are highly dependent on information and systems should renovate constantly. There is more and more information to be processed because companies and their environments get more complex. Products are enhanced with more features because of constant innovation. Also the internet society adds an interesting element in this complexity which is the chaining of activities. We depend more than ever on others and the exchange of information is key to keep up with this contest.

Systems take care of this stream of information, but only if they are designed well. Over the years this has resulted in various types of solutions. Companies, especially the larger ones have applied there own resources in building a system. Then other companies took over this specialization and they designed and developed specific packages that were sold to other companies. Outsourcing followed on the trend that companies should focus on their core business. Off-shoring is somewhere in between all these developments. Off-shoring is a process where a demanding company designs it own system, but will use the human resources of others
