Do you know what the difference is between 1/2 Stage and KCI2 Assure?
1/2 stage is as it sounds. 1 stage means they expect the entire installation to be done in a single visit; 2 stage means two visits, e.g. the internal install done separately from the external install.
KCI are the order progress stages: KCI1 = order accepted, KCI2 = order committed, KCI3 = order complete. If they need to do a survey or further planning before committing to deliver, then this takes place before KCI2. The order could therefore be rejected before KCI2 if it's found to be infeasible or too expensive to deliver.
