Turning a route-planning judgement into options you can compare — and a choice you can
defend.

The bottom line
Name and measure what matters — here, five risks — and route-planning
becomes an optimisation problem. For you, that buys four things:
🛡 Defensible
Every route shows why it was chosen — the assumptions are explicit, auditable and repeatable.
⑂ Options
Several genuinely different courses of action — not one black box.
🎚 Control
Your priorities drive the result. The maths serves judgement.
⚡ Speed & consistency
Seconds, not hours — and the same answer every time.
The rest of this talk pays off each promise. Watch the badges below.
The problem we're solving
Move a team from A to B across ~50 km of country.
Not all ground is equal — some is dangerous. There are countless routes.
What matters more?
There's no single "best" — drag the slider and the sensible route changes. Today an
expert eyeballs this: slow, varies by planner, hard to justify.
The move: make it measurable ⭐
Name the factors that matter — here, five plain risks.
Put a scale on each (0–1). Then score every patch of
ground: vague "danger" becomes data.

The same machinery fits any factor you can name — risks, or success factors like
distance.
Proof ① — you stay in control
How much each risk matters is your call: a dial per risk. Low = avoid
it; high = tolerate it. The maths serves your judgement, it doesn't replace it.
Drag a dial. Tolerate the bandits and the route takes the shortcut through the
town; avoid them and it swings well clear.
One number per step
Combine the dialled risks (plus a little for distance) into a single
cost to cross each patch. A route's cost is just the
sum of its steps.

running total: 0.0
Each bar is one step's cost, coloured by which risks drove it.
Proof ② — fast & consistent
With a cost on every step, finding a cheapest route is a well-understood
problem. The computer weighs thousands of paths in a blink —
· same inputs → same answer, every time.
Proof ③ — options, not one answer
We deliberately surface three genuinely different routes — then
you choose the one that fits the day.
Same map, same metrics — the planner's best route plus two real alternatives. The
decision stays yours.
Proof ④ — defensible by construction ⭐
Every route carries its reasons: the cost, broken down by risk,
step by step. Click any step to see why.

Total → route → step → reason. "Why not the faster route?" — here's the answer, by risk.

The old way
Eyeball the map → one route, in someone's head, hard to justify
and impossible to reproduce.
The measured way
Name the factors → measure them → optimise the outcome: three
defensible options, under your control, in seconds.
All four promises — now paid. ↓
What it unlocks
One consistent method across every planner and scenario — and
what-if in seconds as conditions change: a storm rolls in, night
falls, a road closes. Re-dial, re-plan, re-justify.
The metrics don't make the decision — they make your decision explainable.
