Lecture 1 An In troducti on to Software Engin eeri ng
what does software engin eeri ng concern?
1) Software engineering is concerned with theories , methods and tools
for professi onal software developme nt.
2) Software engineering is concerned with cost-effective software
developme nt.
What is software?
Software in cludes:
computer programs
data structures
documents
What is the two types of software products
Gen eric software( 通用软件)and custom software (定制软件)
The three key eleme nts of a successful software project are:
on time , within budget , satisfies the user s needs
Gen eric activities in all software processes are:
Specification (描述),Developme nt (开发),Validati on (有效性验证)
Evolution (进化)
The attributes of good software include:
Maintainability (可维护性),Dependability (可依赖性),Efficiency (有效 性)9 Acceptability (可接受
Lecture 2 Software Processes
What is a software process model
A software process model is an abstract represe ntati on of a software
process. It prese nts a descripti on of a process from some particular perspective.

1) 这种模型把软件过程划分成几个顺序的阶 段。阶段间具有依赖性,前一个阶段结束,后 一个阶段才能开始;
2) 这种模型很难对用户变更做出调整,只适用 于需求非常清楚和需求变更被严格限制的情
况下
Describe the basic principle of evolutionary development and its two types
进化式开发的基本思想是先开发一个原 型给用户使用,通过用户反馈意见来不断修改 系统直到最后成熟,所以又被称作快速原型开 发方法。它不主张将描述、开发和有效性验证 等活动分开进行,而是让这些活动迭代执行, 同时让这些活动能得到快速的反馈信息。
进化式开发有两种基本类型:探索式开发 和抛弃式原型法。

在这种开发方式中,系统不是作为一个整体 交付,而是被分解成若干个增量,每个增量交付 系统的部分功能。用户的需求按优先级排队,优 先级最高的需求被放入最早交付的增量中。这 样,优先级最高的系统功能就 得到最多的测试, 系统的可靠性较高。
