Dear Khun Lor,
If we would make assignment on this, we would indeed do this via a seperate PO, it's not connected to the contract for roll out.
To understand your suggestion right, you would send me 1 chargeable person and 2 for training on the job (cost carried by ISB).
In case we would come to full support transaction for 2 or 3 people, that would naturally add up to billable hours and thus like you say...."good for support cost this trip".
Is my understanding correct?
