Most of the adoption process and SDLC tools, try to reason difficult, because of its steep learning curve, lack of tool integration, high initial investment costs, ongoing maintenance, special skills requirements, and to the specific needs of administrators. The results, including SDLC tools, total cost of ownership is difficult to afford. Therefore, CIO faces a challenge to prove since the expense will not touch any of the factors that can be estimated, their expenses are reasonable.Improve the software development life cycleWhen Microsoft first released Visual Basic, when, on the adoption of reducing its plexity so that Windows software can be widely applied. The use of Visual Basic , Microsoft let hundreds of millions of developers to quickly develop client / server applications. Recently, the use of Visual Studio. NET, Microsoft also provides developers with an easy tool for developing distributed applications and technology. Through the Visual Studio 2005 Team System, Microsoft is addressing the increasing plexity of the application and its design, development and deployment of the necessary lifecycle issues. This is by providing the necessary tools and guidance to be able to foresee, repeat the results (without paying the cost of production efficiency and innovation) achieved.Information exchange: report of the operation by reducing overhead and team members to find new channels of munication, Visual Studio Team System focuses on better munication.From the team members through automated tools used to gather information, you can simplify the reporting process. From the Visual Studio Team System collected data stored in the data warehouse, which makes the project status reports and visibility can be oriented to all members of the software development team, even outside the project team stakeholders.Distributed System Designers (Distributed System Designer) will be demand for application development and deployment into enables developers and operators to municate mon language (SDM).Integrated tools: Visual Studio39。參考文獻(xiàn)[1] Server :P2028.[2] SERVER :P60123.

In addition, they also help of new technologies to expand their business functions, and develop new business opportunities. Since the IT departments have received technical support tasks that moment, they will bee the most critical role in business strategy.Companies want from their IT investments in the project to obtain the maximum profits, which means that IT departments need increasing pressure, the sooner the better to plete the work. Because of the higher pursuit of costeffectiveness, making predictability of demand for IT projects is growing. However, this often result in cumbersome processes and monitoring of cost consumption, it is only fees should be shifted to a different question. Opportunity to pay the development costs of a large investment of time, resulting in the expansion of IT budgets.Complex applications generally require the development of welltrained team of multivessel to achieve. Development team to make a mitment to any mitment for the major terms, exchange of information is an essential element of success. The new Visual Studio Team System extends the Microsoft of the outstanding features, namely, providing tightly integrated with business, scalable, and can increase the probability of success of the lifecycle tools to provide users with more efficient tools. The success depends largely on the plexity of the solution, in order to reduce the plexity of the delivery of solutions, the team between the need for a full exchange.IT solutions for the challenges of buildingAlthough many IT solutions, project work products are software, but software is not generating the project the contrary, software is a means to achieve its objectives, namely, driving a different business value. Need to respond to different risk and increase predictability of success, most IT departments turning to a variety of tools and processes to support SDLC. Were designed to improve the efficiency of software development are not satisfactory attempts. These attempts, some because the implementations are too plicated, so I did not achieve the desired object
