Perform Acceptance
(with the vendor), i.e. a series of test
to demonstrate that the system complies with the specs.
(
E.g. Comparison between calculation and measurement of OF
for 5 field sizes)
IF
the tests are successful
2/4
you pay for the equipment, which becomes yours.
ELSE
you ask for the problems to be fixed
N.B. No specs means no meaningful acceptance tests !!
How did you TPS acceptance tests look like?
