The old Ladok system was designed and developed in the mid-eighties and began to show the obvious signs of the need for a redesign in the mid 1990’s. A large re-engineering project called “Nouveau” was then started in 1995. Its focus was on the documentation part of the system, moving towards a new technology structure and a new graphical user interface. Nouveau also included new functionalities and a three-tier architecture. The development method used during the first 3 years of this project was a classic waterfall approach. However, by 1997 a number of issues were emerging that suggested a new approach was required.
