LCG 12 June Rene BrunBlue print RTAG9 Evidence It takes time to build solid fundations more than 6 years for Geant3, PAW, ROOT The process must be validated by users in different experiments in different configurations In the long term, users prefer general purpose frameworks to experiment-specific frameworks because users work in 3, 4 experiments during the life time of any framework People vote with their feet
