Why every number you report improves as the gap opens

Every figure you send upward gets better during exactly the period when this is happening, and that is not a coincidence.

This is the step that explains why nobody has told you about this. Every figure you report to your own leadership gets better during exactly the interval when the gap is opening, and every one of those figures is correct.

Every needle is correct and the panel has no space where a gauge for the tank would go. The good news and the accumulation are one event.
What moves: three needles on the reporting panel all rise into the good range while the reservoir rises behind it, with no needle anywhere for its level.

Work through it. More is produced, so throughput rises. Less of it waits for somebody to look at it, so time-to-ship falls. The queue of things waiting on a person gets shorter, because fewer things are waiting on a person. Each of those is a real improvement in the thing it measures.

The last row is worth dwelling on

Reviewer load usually does not move, because it cannot — the same people have the same hours. From the outside that looks like stability. What it actually means is that the examined quantity is pinned while the produced quantity grows, which is the gap, visible in a number you already have and do not report.

Every term this page uses

produced-to-examined
How much work your team produced, divided by how much of it somebody actually looked at.
examined
Looked at by somebody with enough context to have caught a problem. Not the same as having passed through a review step.
remainder
Work that was produced and not examined. It does not go anywhere — it merges into what everything after it is built on.
judgment
Deciding whether a piece of work is good, which needs knowing the domain well enough to recognize a wrong answer.
inspection
Checking finished work at the end, rather than changing how the work is made.
checkable
Able to be judged without understanding the whole of it. The property that decides how much needs judgment at all.
constraint
The thing that limits output. Adding more of anything else does not help until it moves.
rework
Work that had to be revisited after somebody called it done.
vigilance
Staying alert for a rare problem across a long stretch of time.

Taken as already known, and so not defined here: agent, model, review, throughput, headcount. That list is a claim about who is reading, and it is printed so it can be argued with.
