Ease of use ranges in importance from less important, for a one-time experiment to be run only by the application's developer, who is intimately familiar with the software; to very important, for a production application to be used by a variety of semiskilled operators within a single organization; to extremely important, for a mission- or safety-critical application, or a commercial application intended for distribution and resale.

包括以下三种情况：该软件的开发者，他对该软件非常熟悉，在编程中会经常进行一次性试验，此时易用性就不太重要；一个团队中对该软件半熟悉的操作员来使用该软件，此时易用性很重要；在mission- or safety-critical的场合，或者是准备发布销售的商业软件，此时易用性则非常重要！
