Re-evaluate scenaria for all branches
Business experts interview 
GroupSystem
This activity studies the interdependencies among  choices  made previously per  branch . Clearly the global preferred scenaria resulting of the union of preferred branch scenaria can be unsustainable for the organisation, for example in terms of costs or human resources. The preferred set of scenaria must be re-evaluated in the light of the branch scenaria interdependencies. This might result in the selection of different branch scenaria than the ones resulting of the previous step.
