Also, preliminary information on probable cause, including technical evaluation, could be included to enable allocation of acceptance criteria. The aim of this section is to provide simple guide line to help Customers choose appropriate figures for RAM requirements. In this case two choices may be considered for addressing the target of minimising standstill time: Highlight the top most problem contributors affecting contractual service performances,! The following example shows the integration process and the programme implementation when: If technical modifications are necessary, the Supplier should precisely quantify the consequences of modified configuration e.
