Compare Only with Yesterday’s Self

Compare sideways and only anxiety is left; compare against yourself and method is left — quarterly delivery quality is the measure.

A colleague once asked a very practical question: who exactly are we supposed to compare ourselves with?

Let me put the view first. Compare with peers and you are comparing rank; compare with yesterday's self and you are comparing ability. Glacier people compete only with themselves, and today's Glacier is benchmarked only against the Glacier that came before. Why? Because rank is too dirty a variable.

Why comparing sideways carries no information

Whether a deal closes has the market mixed into it, the window, the other side's internal process, and some luck as well. Put yourself next to another firm and the endowments differ, the starting points differ, the luck differs. The conclusion sounds good and guides none of tomorrow's actions. It leaves one thing behind: anxiety. And what anxiety eats is exactly the attention that should have gone into improving. Anxiety produces nothing.

Comparing against yourself is far cleaner. A control group means holding everything constant except the one thing you want to look at. Same situation: how would we have handled it two years ago, how do we handle it today, and at which step is the difference. One variable is left, and that is method. We are fairly sure of this one.

Turn the line into a measure

Compare only with yourself and it easily becomes a pleasant phrase. So we gave it a scale.

Client word of mouth is the only ranking we care about: every quarter's delivery quality has to beat the previous quarter across the board. Four quarters a year means passing your own gate four times a year, once every ninety days on average, four times denser than a year-end review. Which is to say, no problem hides longer than ninety days. The density is the discipline.

The tempo has to be designed too. One year we compressed the whole year's target into the first quarter and used the remaining three to work on the inside: reviews, training, writing methods into something that can be handed over. It sounds aggressive. It was for composure. Spread evenly across four quarters instead? The whole year goes on chasing the schedule. Twelve months, not one of them left for yourself. Never a stretch of time free to get stronger.

The repeat mandate is the other end of the same measure: whether an existing client hands us the next round. That record cannot be gamed.

Do not chase the lag in perception

A client once said something in private that stayed with me for a long time: this team iterates so fast that the market's perception of them is still stuck in the past.

I take it as praise. The capital market's memory is about appearances, not about facts. A company that has done solid work for years and rarely appeared has a thick business ledger and an empty perception ledger. That is a burden and also room — no old labels to wash off, and the next appearance can speak from today's facts. But it does not need handling in a hurry. Do today's work well and the lag catches up on its own.

So should the tempo be changed in order to be seen? No. When the window does not come, we can sit on the cold bench.

Endurance, not sprint. Placing in an endurance race is not decided by any one lap; the result only stands once the whole distance is run. Compare with others and you are comparing lap times. Compare with yesterday's self and you are comparing the whole distance. The long run is simply changing the control group.

Comparing only with yesterday's self has one more benefit: there is always something to compare with. Markets run high and low, the table rises and falls, but yesterday's self is there every day, never absent, never padded. So far it is also the only variable we fully control. A long-distance runner does not want a placing. He wants to still be running.
