Is this Innes or your socks talking?
If DI said it, he is as bad as LG because it is total BS.
First, they might have to wait on something that happens before datalock, but you do not need to wait on datalock itself. If they are not waiting on the SAP, and have the data collected and scrubbed, then they snap their fingers and say "locked".
Second, if they are implying the first two steps (SAP and scrub) are done, that was never communicated. So I guess "communicate information when necessary" means they have no need to communicate.
