Classification work
Exports your systems load the first time.
Requirements are read back as filters before anything is run. A sample is pulled and read before the full run is committed. The result is auditable line by line.
Re-check scheduling
Deciding how often each part of a file needs looking at again, by how fast it goes out of date.
Industry mapping
Translating described activity into the classification your systems already use, including where it fits badly.
Delivery verification
A final pass against the agreed criteria at the point of handover, not at the point of assembly.
