The Decision Framework for Timing Every Business Move

It’s not about guessing what happens next. It’s about knowing what’s happening now.

Instead of predicting the future, TSF translates complex data into clear, immediate direction—showing when to hold steady, when to grow, and when to protect. It gives leaders a simple, visual way to recognize opportunity and risk in real time, so actions match reality.
Building a business is hard. Running one shouldn’t be.
When you’re building, everything’s uncertain — you’re creating structure, systems, and stability from scratch.
But once you’re running, the game changes. It’s not about building anymore. It’s about maintaining what works and guiding what’s next. And in that game, there are only three possible moves:

Hold. Grow. Protect.

Every decision — every hire, every order, every campaign — falls into one of those three categories.

Hold. Grow. Protect.

The hard part isn’t choosing what to do. It’s knowing which one to do right now. That's where TSF comes in.
TSF tells you, at a glance, whether this moment is normal or not — and whether it's time to hold, grow, or protect.

The Forecast That Defines Normal
When performance stays within ”normal,” you hold. When it moves outside, you act.
Each TSF forecast defines that boundary. The gold line represents the expected value for each date, chosen from more than 800 competing forecast models based on proven historical accuracy. The green zone marks the confidence interval built from that same accuracy record — it's the statistical range of what’s normal. When actuals fall inside the zone, conditions are stable. When they break above or below it, opportunity knocks.

Fewer Stockouts. Less Overstock. No Guessing.

Start each month with clarity.
The green zone defines your safe operating range for each day — your best- and worst-case expectations based on real data.
Watch volatility, not just direction.
When the band widens, expect more variability — it's your signal to build flexibility into cash flow or supply.
Plan inventory, ads, and staffing within the band.
The top of the band is the strong demand scenario. The bottom of the band is the conservative scenario. Plan your orders and budgets around the range that fits your risk tolerance.
Measure signal vs. noise.
If actual results stay inside the band, you're fine. If they consistently move above or below it, something has genuinely changed — that's a planning insight for next month, not a daily fire drill.
