5. Requirements collection: sorting
Requirements are classed either as
Simple for ‘small’ requests
And are handled at the working group level
E.g. time-dependent fields, modelling improvement,..
Complex or major items
Are raised at the TSB level
Discussed and prioritised
E.g.: cuts per material/region, new G4Exception, migration to STL
