I have recently used several systems that are not usable but have been declared successes. Success means that their use is increasing, no one was fired, and the usability problems are solved by the users who either work much harder or through surrogates. After defining usability, I describe these systems and provide a list of reasons why these systems are both unusable and successes, seemingly a paradox for human factors. The article concludes by explaining this paradox, noting several ways this can happen, particularly when stakeholders’ viewpoints are excluded or discounted by designers and by other types of users.

无法使用的系统如何取得成功：当您不是利益相关者时

我最近使用了几个不可用但已宣布成功的系统。成功意味着他们的使用在增加，没有人被解雇，可用性问题由更努力工作或通过代理的用户解决。在定义可用性之后，我描述了这些系统并提供了为什么这些系统既不可用又成功的原因列表，这似乎是人为因素的悖论。文章最后解释了这个悖论，并指出了这可能发生的几种方式，特别是当利益相关者的观点被设计师和其他类型的用户排除或打折扣时。
