One yardstick at a time, across the whole team

Open almost any review tool and you get a form per person: one employee, every criterion, top to bottom. It feels organised. It is also close to the worst possible order for accuracy.

What the halo effect does to a form

When you assess one person across many dimensions in a single sitting, your impression of them on the first dimension colours every dimension after it. Someone who communicates well starts to look reliable. Someone who missed a deadline starts to look careless about quality too. The ratings stop being independent measurements and become variations on a single overall feeling.

This is one of the oldest findings in the assessment literature, and it does not go away because the rater is well-intentioned or experienced.

Turning the board sideways

Persohap scores one yardstick across everybody, then moves to the next. The manager places their whole team on a single ladder for quality of work, then does the same for delivery, and so on. Each pass is a genuine comparison on one dimension, and the impression formed during the quality pass has nowhere to leak into the delivery pass.

It also matches how managers already think. "Who is strongest on quality?" is a question people answer naturally. "Rate Anna on six unrelated axes" is not.

Deliberately not a forced curve

The columns have no caps and no targets. Putting the entire team on the top rung is allowed, and the board says so on screen.

Ranking people against each other is a good way to lose the strongest ones. Bands here are absolute thresholds, and they stay that way — if everybody genuinely cleared the bar, the system should say so rather than manufacture a spread to fill a quota.

The cost

Managers have to make several passes instead of one, and each pass forces a real comparison rather than a gut summary. That is more uncomfortable. It is also the entire point.
