计算机支持的协同工作

• There needs a synchronized or asynchronized tools based On CSCW technology for supporting the cooperative activities to detect and resolve the trouble.
4、A Workflow management system Used for CSCW in SE(1)
In the process of the development of large complex software systems, there involved a large number of people, who take care of the development task of the same or different part or functionality of the system. It is impossible for them to work completely independently. Their tasks are associated greatly and they need intensive cooperation. The associations of different part is called interface in the terms of software development.

Specially, the modification of a interface often involves a great deal of discussions and negotiations of the group of people involved. It can only be made successfully when members of group reach an agreement and make their own part of modification accordingly. Otherwise it is impossible for the software to function properly. Furthermore, the kind of process is very dynamic.

3、Supporting Tools
Two types of tools: • General tools: such as some electronic conference systems; white board; and some other tools, for example application sharing. • Specialized tools: one developed based on the features of SE. There are few tools of the later kind developed up to now. Following is the two we propose to develop.

4、A Workflow management system Used for CSCW in SE(4)
•The workflow management systems and discussion tools should help to resolve this questions well. • The automatic management of process of the development,especially the process of the modification of the interfaces should be got by the workflow management system. • But current workflow management systems are not able to meet the requirement. We propose a function extension of such systems to meet the functional requirement as shown in the following figure:
2、The requirements
• Software development is a typical activity conducted by group of people. It is estimated that 70% of time and effort of the developers is spent on each other’s cooperation in the development of the large complex software systems,which occupied 85% of total costs. • How to improve the efficiency of cooperation is becoming the key element of the software engineering. • CSCW is one of the effective means to solve the problem.

• It is ever-present that there are lot of trouble caused by the modification of interfaces. • In order to avoid the trouble,it is necessary to work with cooperative activities of each other.
5、The Tools Used for Process Monitoring and tracing in the Software Development(1)

Process monitoring tool
The monitor have following function: Over time monitor,That is the monitor keeps check if some event is overtime. It gives an alarm if it happens. The monitor can be incorporated into workflow management system.

1. An Introduction
• There a lot of researches and good results obtained in the CSCW in SE. • We would like to give a brief introduction to our resent work on the research on CSCW in SE.
especially (4) (9) (11) can fulfill the requirement of the dynamic interface for discussion,which facilitate the automation of process management of software development.
