# A boardroom that argues the criteria, not just sums them

> Decision matrix tools sum weighted criteria into a score. SynthBoard runs a multi-agent boardroom that argues the criteria themselves. Different mechanic, deeper output.

Decision matrices turn a hard call into a weighted-sum spreadsheet. SynthBoard runs the multi-agent debate that argues which criteria should even be on the matrix — and why the obvious weights are wrong.

## What you get

### A panel that debates the criteria

Five lenses argue which factors matter, how much, and which ones the obvious framing missed entirely.

### Steel-man on the weights

Decision matrices are sensitive to weight choices. The synths argue the alternative weighting before you commit to the score.

### A synthesis, not a number

Every session ends with a recommendation and watch-outs — a conclusion you can defend, not a score that hides the disagreement.

## Questions people ask

- What criteria are missing from the matrix I just built?
- How would a multi-perspective panel weight these factors differently?
- What is the steel-man case for the option my matrix scored lowest?
- Where is my matrix's scoring leaning on confirmation bias?
- Should I commit to the matrix winner — or is the next-best option actually closer than the score suggests?

## Ideal Synth lineup

- **The Strategist** — Long-range positioning. Maps competitive dynamics and strategic options across multi-year horizons.
- **The Data Scientist** — Evidence-first. Pulls the analysis behind every confident claim.
- **The Skeptic** — Assumption stress-test. Questions every premise. Finds blind spots others miss.
- **The CFO** — Financial discipline. Pressure-tests unit economics, runway, and capital allocation.
- **The Empath** — Human factor. Reads the emotional, cultural, and team dynamics behind the decision.

## Sample synthesized outcome

**Consensus score:** 76%

**Recommendation:** The matrix is missing a "reversibility" criterion and over-weighting "time-to-market." With reversibility added at 20% weight and time-to-market reduced from 30% to 15%, Option B (the second-place finisher) becomes the consensus pick.

**Key recommendations:**
- Reversibility is the most common missing criterion in matrix decisions
- Time-to-market is rarely as load-bearing as teams weight it
- Option B and Option A are within margin-of-error on the original matrix
- The matrix structure is sound; the weights and missing criterion are the issue

**Watch out for:**
- Do not let the new matrix become the new locked-in answer — keep it loose
- Document the reasoning for the weight change so future decisions can reuse it
- Revisit the matrix at 30 days with actual evidence to refine the weights

## Why SynthBoard for this

### Multi-agent debate vs single spreadsheet

A matrix sums one person's weighting. SynthBoard runs the debate that questions whether the weighting is right.

### Surfaces missing criteria

The biggest failure mode of decision matrices is the criterion you forgot. The synths catch them.

### A defensible synthesis

A score is opaque. A written synthesis is defensible — you can argue it with your team.

### Rerun with new framings

Test the same decision through five different framings. Matrices reward locked-in commitment; SynthBoard rewards exploration.

## Common questions

### Is SynthBoard a direct replacement for a decision matrix tool?

For most decisions, yes — and for a deeper reason. A matrix optimises the math of a decision you have already framed. SynthBoard optimises the framing itself. Use the matrix for tactical multi-criteria scoring; use SynthBoard for the strategic decisions where the framing is the call.

### When should I use SynthBoard instead of building a matrix?

When the decision is strategic and the criteria are not obvious. When you want adversarial input on the weights, not just a sum. When you want a written synthesis you can defend to your team. When the matrix score feels suspicious — because it usually is.

### When is a decision matrix still the right tool?

For tactical procurement decisions with truly objective criteria. For vendor scoring where the weights are agreed in advance. For decisions that are genuinely about summing pre-agreed factors. Matrices are great when the framing is settled and the math is the question.

### How does the price compare?

SynthBoard is free to start; paid tiers run low double-digit dollars per month. Most decision-matrix tools are free or low-cost spreadsheet templates. The two are not in the same product category — comparing on price misses the mechanic difference.

### What does SynthBoard NOT do that a decision matrix tool does?

No automated weighted-sum scoring, no vendor-comparison template library, no procurement-grade audit trail, no integration with sourcing workflows. SynthBoard is a structured debate room; matrices are scoring tools.

### Can I use SynthBoard to stress-test a matrix I already built?

Yes — and it is a high-leverage use. Share the matrix, the criteria, the weights, and the score. The panel will argue the weights, surface missing criteria, and steel-man the option your matrix scored lowest. Most matrices change materially after one SynthBoard session.

## Perspective from The Data Scientist

> A decision matrix hides the disagreement inside the weights. SynthBoard makes the disagreement explicit — and the decision better.

## About SynthBoard

SynthBoard is a standing board of AI experts that argue with each other on purpose, remember every call you make, and learn from how those calls played out. Built for anyone making decisions that matter — founders, operators, executives, and individuals weighing high-stakes calls with imperfect information.

Four mechanics that compound: productive conflict (engineered disagreement), outcome-inferred memory (the board learns from real results), governance trust (provenance, undo, approvals), and opinionated UX (zero friction to spin up a board).
