The Orange Juice Test is a method used to evaluate potential service providers, particularly consultants or software houses. It was first mentioned by Gerry Weinberg in his book "The Secrets of Consulting" and later explained by LeRoy, the president of a custom software firm, who had employed the author's services. The test involves posing a hypothetical task that requires a significant amount of effort and resources to accomplish, such as serving 700 people at a sales breakfast with freshly squeezed orange juice. The provider's reaction is then observed, with those who express defeatism or delusion about their ability to complete the task being eliminated from consideration. Those who propose a realistic approach and acknowledge the difficulty of the task are considered for hire. This test helps eliminate unqualified providers and identify those who can deliver on their promises.
