(Decisions fail when the reasoning disappears)

Most decisions look clear the day they’re made.
But weeks later, no one remembers why they were made.

And when the “why” disappears, the decision itself becomes fragile:

  • people reopen it

  • people misinterpret it

  • people assume it was arbitrary

  • people adapt incorrectly

  • future choices become inconsistent

Here’s the tool that prevents that.


THE TWO-LAYER DECISION TEMPLATE

Every time you document a decision, capture:

Layer 1 — The Decision

“What we are doing.”

Layer 2 — The Rationale

“Why we chose this option over the others.”

That’s it.

Two layers.
Five seconds.
Massive payoff.


⭐ Why It Works

Most decisions don’t fail because they were wrong.
They fail because the reasoning behind them evaporates.

The rationale is crucial because it contains:

  • assumptions

  • constraints

  • context

  • tradeoffs

  • intent

  • the condition under which the decision was valid

This keeps future you (and everyone else) from guessing.


⭐ When to Use It

  • Product decisions

  • Strategy choices

  • Resourcing

  • Prioritization

  • Process changes

  • “We’re doing X instead of Y” situations

  • Anything involving multiple stakeholders


⭐ Example

Decision:
We’re launching the MVP without feature B.

Rationale:
Feature B increases scope by 3 weeks; customer feedback will determine if it’s worth adding; timeline is the constraint, not completeness.

Now the decision makes sense — and continues making sense months later.


⭐ Try It Today

Take one recent decision and add the rationale beneath it.

You’ll immediately see why this tiny habit has huge returns.
