SolvProb Decision Matrix

Weighted Decision Analysis Tool

How to use

Define Criteria: List the requirements (e.g., Cost, Risk) and assign a Weight (1-10) based on importance.
Define Options: List the solutions/vendors you are comparing.
Baseline: In the matrix, choose one option as the reference (Standard). It stays at 0.
Score: Rate other options relative to the Baseline using the dropdowns.

Calculation Logic

Cell Score = Weight × Rating

  • ++ (2) : Much Better
  • + (1) : Better
  • S (0) : Same (Baseline)
  • - (-1) : Worse
  • -- (-2) : Much Worse
Example: If 'Cost' has Weight 5 and an option is 'Better' (+1), the result is 5 points.

Weighted Decision Matrix

Compare alternatives in a Pugh weighted decision matrix: set criteria weights, score options against a baseline, review totals, and export JSON or CSV.

What this tool does

This Pugh-style matrix compares alternatives against a selected baseline. Weight each criterion, score non-baseline options from much worse to much better, and review the resulting weighted totals and recommendation.

Who this is for

How to use this tool

  1. Name the options and choose a baseline
  2. Add criteria and assign each a weight from 1 to 10
  3. Rate alternatives with ++, +, S, -, or -- and add optional justifications
  4. Review totals and the chart, then save JSON, export CSV, or print the matrix

Inputs

Inputs are option names, a baseline, criterion names and weights, relative ratings, and optional justification notes. The baseline is the zero reference for every criterion.

Outputs

The page shows weighted totals, positive/negative/neutral counts, a highest-total recommendation, and a bar chart. Save JSON and export CSV download local files; there is no autosave.

Frequently asked questions

What do ++, +, S, -, and -- mean?

They represent relative performance against the baseline: much better, better, same, worse, and much worse. The tool maps them to 2, 1, 0, -1, and -2.

Why is the baseline always zero?

Pugh scoring is relative. The selected baseline is the reference point, so it receives zero on each criterion while alternatives receive relative scores.

How is the winner calculated?

Each relative score is multiplied by its criterion weight and summed. The option with the highest total is shown as the recommendation; ties use the first highest option.

Can I reopen a matrix later?

Yes. Use Save JSON to download the matrix and Load JSON to restore it later. The page does not save matrices automatically.
