Which is strange, because almost every tool you've been sold treats it as though it were.
Vendors sell accuracy the way economists sell theory: all other things being equal.
All other things are never equal. Thirteen major disruptions hit supply chains in five years. Every accuracy figure earned in calm water got quoted in a storm.
And the forecast that actually gets published has already been negotiated before it ever meets reality, nudged by targets and politics and somebody's optimism. Then it gets graded as though it were pure mathematics.
What matters is the quality of the decisions you make, and how fast you revise them when the world argues back.
Accuracy tends to follow from a system that records what happened, learns from it, and acts. You can't buy it off a shelf.
It started with meeting the same person over and over.
A planner, in a real company, changing the forecast again. In a spreadsheet. For the fourth time that month. With no way of showing anyone why.
Only later did we go and read what the forecasting scientists had found. Most of it was already there.
The research described exactly what we were already looking at. What it never did was produce a product, because the change happens in a spreadsheet, and a spreadsheet sits outside every system anyone could have built one into.
If your manager wants the number up, the number goes up. That's your job and it isn't our business.
We won't block it. We won't lecture you about it. We are never going to build a leaderboard.
What we'll do is make the change quick, write down why you made it, and tell you honestly how it turned out.
Do that for a year and you'll have something planners have rarely had.
We're not trying to correct the real world. We're trying to nudge it.
Every change made through Piwaka is scored against your actuals and your own baseline, by rules that were set before the change was made.
That scorecard lives in your ledger. Not in our marketing.
