How the Decision Maker Works
This decision-making tool uses a weighted decision matrix to help you compare options objectively. Start by naming your options — the things you are choosing between. Then define the criteria that matter to you, such as cost, quality, convenience, or any factors relevant to your decision. Assign importance weights from 1 to 5 for each criteria. Finally, rate how well each option meets each criteria on a 1 to 5 scale. The tool calculates a weighted score for each option and declares a winner.
Scoring Formula
Option Score = Sum of (Rating x Criteria Weight) for all criteria
Normalized Score = (Raw Score / Maximum Possible Score) x 100
The maximum possible score is the sum of all criteria weights multiplied by 5 (the highest rating). This gives a percentage-based score between 0 and 100 for easy comparison.
When to Use This Tool
The decision maker is ideal for comparing job offers, choosing between products or services, evaluating rental apartments, deciding on vacation destinations, selecting a school or program, or any situation where you need to weigh multiple factors against multiple options. It turns gut feelings into structured analysis without removing your intuition from the process — you still define what matters and how much.
The Pros and Cons Feature
Beyond numerical scoring, you can add pros (advantages) and cons (disadvantages) as tags for each option. These serve as qualitative notes that the raw numbers might not capture. Sometimes a single dealbreaker con outweighs a high score. The tags appear alongside scores in the results to give you the complete picture for an informed decision.
Tips for Better Decisions
Be honest with your ratings — the tool only works as well as your inputs. Include both practical criteria (cost, time) and emotional criteria (excitement, comfort) for a balanced evaluation. If two options score within 5 points of each other, they are essentially tied — go with your instinct. Weight your criteria carefully — a criteria with weight 5 has five times the impact of one with weight 1. Save your decision to your browser and sleep on it before committing.
