In the period between 1995 and 1998, websites were almost entirely composed of static html files. They were 100% interfaces but in 1998 the percentage decreased to 90% and in year 2002 they constituted less than 50% of those available on the Internet. This percentage and the complexity of the web applications are inversely proportional. Interfaces websites are in continuous decrease and the complexity of web applications is in a continuous increase. Nowadays, web applications are powered by distributed software implemented using a myriad of languages like HTML, XML, JavaScript, etc. This heterogeneity encouraged the researchers who have had a certain experience with software engineering to explore the WWW and thus they proposed a new approach called Web Engineering. Web engineering is not a perfect clone of software engineering but it borrows many of its fundamental concepts and principles emphasizing the same management and technical activities. Its work products lead to analysis models, design models and test procedures. Within this context many efforts have been addressed towards defining design models for web applications to implement reusable and well structured web applications. The newly proposed approach is the fruit of such efforts. For instance, the FBM-HWA approach falls within the basket of design models.  It is not purely based on an object oriented concept and does not refer to UML for notation purposes , as it is the case in most existing approaches. It models the behavior of web applications using Finite State Machines (FSMs) and simplifies the task of developers and testers at once by providing them with a total overview of the application.  We believe that by modeling web applications with FSMs, it becomes possible to create models that present deterministic responses for unanticipated actions in almost any condition or situation.

在 1995 年至 1998 年期间，网站几乎完全由静态 html 文件组成。它们是 100% 的接口，但在 1998 年，这一比例下降到 90%，而在 2002 年，它们所占的比例还不到 Internet 上可用接口的 50%。这个百分比与 Web 应用程序的复杂性成反比。接口网站不断减少，Web应用的复杂性不断增加。如今，Web 应用程序由使用 HTML、XML、JavaScript 等多种语言实现的分布式软件提供支持。这种异构性鼓励具有一定软件工程经验的研究人员探索 WWW，因此他们提出了一种称为 Web 工程的新方法。 Web 工程并不是软件工程的完美克隆，但它借用了软件工程的许多基本概念和原则，强调相同的管理和技术活动。其工作产品导致分析模型、设计模型和测试程序。在此背景下，人们做出了许多努力来定义 Web 应用程序的设计模型，以实现可重用且结构良好的 Web 应用程序。新提出的方法就是这些努力的成果。例如，FBM-HWA 方法属于设计模型的范畴。  它并不纯粹基于面向对象的概念，也不像大多数现有方法那样引用 UML 来表示符号。它使用有限状态机 (FSM) 对 Web 应用程序的行为进行建模，并通过为开发人员和测试人员提供应用程序的总体概述来简化他们的任务。  我们相信，通过使用 FSM 对 Web 应用程序进行建模，可以创建模型，为几乎任何条件或情况下的意外操作提供确定性响应。
