The Joel Test was created in August 2000 by Joel Spolsky, a Software Developer from New York City, who is a founder and CEO of Stack Overflow, creator of Trello project management software, and ex-Microsoft employee.
The test is designed to rate the quality of a software team, all in about 3 minutes! It consists of 12 ‘Yes / No’ questions that are intended to be quick and simple to answer.
A team is given 1 point for each ‘Yes’ answer - the higher the score the better. So a score of 12 is perfect and means that you have an effective, disciplined team that can deliver. Of course the test evaluates the software team and not the software, so you can have a perfect score and still produce an unsuccessful end product.
