Discuss possible ways to monitor progress in this area, and to steer some immediate concrete work. Possible proposals:
- Define a reference version of Geant 4, emergent from the current validation studies with LHC data
- Identify benchmarks for improvements in the simulations, motivated by specific physics performance goals
- Formulate a recommendation to SFT and the experiments for a new mandate for the Geant 4 validation forum
- Propose a format for future meetings of this type:
o hand over to the revamped validation forum?
o decide to iterate the workshop on a yearly basis?
o setup focused WGs on separate issues (physics aspects, technical aspects, ....)
