简介:原型被描述为成功的机制把用户经验设计(UX)合并到活泼的开发,但是他们进如此的开发的集成不免除困难。原型和最后的应用程序经常用不同工具被开发,它妨碍在设计者和开发者之间的合作并且也复杂化复用。而且,集成的股东象进设计,评估,并且精制一个原型的活泼的过程的顾客和用户那样因为它的反复的性质,不主要是直接的。在一次尝试到处理这些问题,这个工作介绍脚本语言在被用来编码建原型的行为的一个新框架的设计和实现。原型然后被当作和最后的功能共存并且跑的一个分开的方面。因为设计者和开发者在平行研究一样的软件人工制品,用这,框架通讯被提高。当建原型的行为被移开时,原型充分与最后的功能被再使用并且反复地增加了。他们能也即时地被修改实现提供参加机会的设计技术。
