What This Resource Covers
- The four-question decision filter
- Reversible vs irreversible decisions and how to treat them differently
- Constraint check: does this decision address the binding constraint
- Documentation pattern for decision review six months later
Who It Is For
- Owners and executives facing multiple competing growth investments
- Operators preparing a recommendation for the leadership team
- Boards reviewing strategic capital allocation
Why It Matters
- Most failed initiatives were predictable from the original decision memo.
- Reversible decisions deserve speed; irreversible decisions deserve rigor. Conflating them produces waste in both directions.
- Written criteria create accountability and accelerate the next decision.
Key Concepts
The Four-Question Filter
- What constraint does this decision address
- What evidence supports the expected outcome
- What is the cost of being wrong and is it reversible
- What is the explicit success metric and review date
Reversibility Test
If the decision can be reversed in under 30 days with manageable cost, decide quickly and learn. If the decision is irreversible or expensive to reverse, slow down, gather more evidence, and require a written memo and review.
Constraint Check
Cross-reference the decision against the current binding constraint of the business. If the decision does not relieve the constraint, it is movement without progress. Park it and address the constraint first.
How To Use It
- Apply the four-question filter to the next pending decision
- Classify it reversible or irreversible
- Run the constraint check before committing budget
- Schedule the review date in the calendar at the moment of decision
