不要上麦肯锡的当

麦肯锡认为中国应像印度一样发展离岸外包。但这仅仅是外国跨国公司的意图。发展中国软件产业的思路,一直存在着不同的观点。一种观点认为,中国应当照搬印度模式,代表者是麦肯锡咨询公司在2002年所做的《中国软件产业发展战略研究报告》,它主张中国不必发展基础软件,而应像印度那样,主要发展面向出口的离岸外包业务。由于印度发展离岸外包很有成效,这种观点似乎也有道理。不过,近年来中国软件业的实践表明,离岸外包并不能成为中国软件业的主体。实际上,尽管近年来各地对离岸外包支持力度很大,但它在整个中国软件业中所占的比重仍只有2%左右,显然不能成为中国软件业的主体。     

一种面向ERP外包项目的开发成本估算方法

对于软件项目而言,项目成本的有效控制是每个项目取得成功的标志之一。恰当的软件开发成本估算方法将大大提高成本估算的稳定性和可靠性,从而提高项目经理对项目成本的有效控制。本文在深入分析目前业界常用的软件项目开发成本估算方法的基础上,针对ERP外包软件项目开发生命周期的特点,提出了以ERP程序单元为最小单位的一种项目开发成本估算法,即FRICE估算法。该估算方法已经在大量ERP外包软件项目中得到了成功应用、实践和验证,它能有效地帮助项目经理对项目开发成本进行估算、控制和管理。

中国软件外包竞争力分析

在软件企业盈利乏力的现状前,软件外包正在成为目前我国软件行业最热门的话题。中讯进入香港主板、大连华信及海辉成功获VC注资,中软国际向微软和IFC(国际金融公司)发行优先股,软件外包的诱人前景逐渐散发。外包是指企业为降低成本、保留核心业务和提高竞争力而将自己的部分业务委托给外部企业的一种商业行为。大部分外包业务属于离岸外包,即:将业务委托给外国企业的外包方式。软件外包属于软件出口的一个重要组成部分,它指接包方提供相应的软件服务来满足发包方的软件外包或业务流程外包的需求,主要包含企业应用软件设计与开发、应用软件…

Stepwise improvement of the software-process in a multidimensional framework

Software process models, irrespective of whether they are life cycle oriented or not, focus strictly on the activity domain within a single project. This focus is heavily challenged by COSMOS, a multidimensional software process model. In addition to the activity structure, it takes into account also the communication- and infrastructure in which software development takes place. This three-dimensional framework meets special challenges due to incorporating software reuse and object orientedness into large scale software production and it allows for adequate planning of various activities controlling software development which are not directly attributable to a specific project, but which might run in parallel to a host of projects.This paper reports on investigations concerning the mapping of this multidimensional software development model on a software process maturity scale, analog to the one proposed by Humphrey (1989).

MND-SCEMP: an empirical study of a software cost estimation modeling process in the defense domain

The primary focus of weapon systems research and development has moved from a hardware base to a software base and the cost of software development is increasing gradually. An accurate estimation of the cost of software development is now a very important task in the defense domain. However, existing models and tools for software cost estimation are not suitable for the defense domain due to problems of accuracy. Thus, it is necessary to develop cost estimation models that are appropriate to specific domains. Furthermore, most studies of methodology development are aligned with generic methodologies that do not consider the pertinent factors to specific domains, whereas new methodologies should reflect specific domains. In this study, we apply two generic methodologies to the development of a software cost estimation model, before suggesting an integrated modeling process specifically for the national defense domain. To validate our proposed modeling process, we performed an empirical study of 113 software development projects on weapon systems in Korea. A software cost estimation model was developed by applying the proposed modeling process. The MMRE value of this model was 0.566 while the accuracy was appropriate for use. We conclude that the modeling process and software cost estimation model developed in this study is suitable for estimating resource requirements during weapon system development in South Korea’s national defense domain. This modeling process and model may facilitate more accurate resource estimation by project planners, which will lead to more successful project execution.     

基于构件的面向项目评审领域应用框架技术研究

软件复用是在软件开发过程中避免重复劳动的解决方案,但要设计在许多领域都通用的可复用业务组件是很困难的,而面向领域的复用是在一个特定应用领域中实现复用;因此,设计大粒度复用的应用框架对于提高软件的生产率和软件质量具有重要的意义;文中以软件复用为出发点,基于构件化软件的开发思路,对软件的构件技术、领域工程、面向领域的应用框架技术进行了深入的研究,提出了基于需求驱动的面向领域应用框架的开发方法,并详细说明了该方法在项目评审领域的应用.     

基于类推和灰色模型的软件阶段成本预测

准确预测软件成本是软件工程领域最具挑战性的任务之一。软件开发固有的不确定性和风险性,使得仅仅在项目早期预测总成本是不够的,还需要在开发过程中持续预测各个阶段的成本,并根据变化趋势重新分配资源,以确保项目在规定的时间和预算内完成。由此,提出一种基于类推和灰色模型的软件阶段成本预测方法——AGSE(Analogy & Grey Model Based Software Stage Effort Estimation)。该杂交方法通过合并两种方法的预测值得到最终的预测结果,避免了单独使用其中一种方法预测时存在的局限性。在真实的软件项目数据集上的实验结果表明,AGSE的预测精度优于类推方法、GM(1,1)模型、GV方法、卡尔曼滤波和线性回归,显示出较大的潜力。     

基于CMM的软件过程改进实践

Understanding the use of an electronic process guide

This paper presents a case study of the installation and use of an electronic process guide within a small-to-medium software development company. The purpose of the study is to better understand how software engineers use this technology so that it can be improved and better used to support software process improvement. In the study the EPG was used to guide new processes in a software improvement programme. The use of the EPG was studied over a period of 8 months with data collected through access logs, by questionnaires and by interviews. The results show that the improvement programme was successful in improving project documentation, project management and the company's relationship with its customers. The EPG contributed to the improvement programme by providing support for the creation of templates for key project documentation, assisting with project planning and estimation and providing a forum for discussion of process and work practices. The biggest improvements that could be made to the EPG would be to provide better navigation tools including a graphical overview of the process, provide tailoring facilities, include examples and experience and link to a project management tool.     

Antecedents of open source software defects: A data mining approach to model formulation, validation and testing

This paper develops tests and validates a model for the antecedents of open source software (OSS) defects, using Data and Text Mining. The public archives of OSS projects are used to access historical data on over 5,000 active and mature OSS projects. Using domain knowledge and exploratory analysis, a wide range of variables is identified from the process, product, resource, and end-user characteristics of a project to ensure that the model is robust and considers all aspects of the system. Multiple Data Mining techniques are used to refine the model and data is enriched by the use of Text Mining for knowledge discovery from qualitative information. The study demonstrates the suitability of Data Mining and Text Mining for model building. Results indicate that project type, end-user activity, process quality, team size and project popularity have a significant impact on the defect density of operational OSS projects. Since many organizations, both for profit and not for profit, are beginning to use Open Source Software as an economic alternative to commercial software, these results can be used in the process of deciding what software can be reasonably maintained by an organization.
