The document discusses the challenges of defining business rules for digitalization. Lars Nyberg from the Modernisation Programme is working on a project to rebuild and expand IT systems used for company registration. There are about 30 projects between 2009 and 2015 aimed at streamlining processes, reducing manual work, and increasing self-service. Defining clear and consistent rules is difficult as rules are currently hidden in legislation, code, and people's heads. The solution is to align and document all rules in one place, simplify rules, establish minimum requirements, and make intelligent IT systems with advice and alerts. A rule can define what can be done, like requirements for a company board. Rules are categorized into processes, concepts, and decisions.
