Why does accuracy keep tripping up our team, not the data itself?

You and your team can gather almost anything now. That part works. Where it breaks is the last step — the one where someone actually checks that what was captured matches what was required. That step keeps getting skipped, by all of you, in the same place, under the same pressure. This is not a skill gap. It is a sequence problem. You move to the next task before finishing the one in front of you. Each person assumes the last person checked. No one did. The requirement was never the hard part — reading it fully, and holding each other to it, is. This will not be solved by one person trying harder. It is solved by the team agreeing, out loud, on where the check happens and who owns it. Decide that together now, not after the next error.
