Three ways a group decision goes wrong
The loudest voice wins.
The most senior or most insistent person sets the priorities, and the room follows.
In Vesta, everyone agrees on priorities before scoring any option.
The criteria drift to fit the answer.
Once a favourite pulls ahead, the criteria get reworded until it wins.
In Vesta, whoever sets the criteria works with the ranking hidden.
Nobody remembers why.
Months later, nobody can say who changed what, or why this option won.
In Vesta, every change is logged: who, what, before and after.
Decide alone, or with a team.
Give each person a role.

Questions
What decisions is Vesta for?
Any choice with several options and several things to weigh: a job offer, a flat, a software vendor, a hire. Criteria can be numbers, like price, or judgements, like culture.
How are the weights calculated?
With the Analytic Hierarchy Process (AHP). You drag your criteria into order, or compare them two at a time, and AHP turns your answers into weights.
Can I use it with a team?
Yes. Invite people by email and give each one a role: modeller, evaluator, adjudicator, facilitator or viewer.
Is Vesta free?
Yes. Sign in with Google and start a project.
