We summarize the key points for server replacement of shared hosting services to reduce user impacts. Currently, shared hosting services are widely spread because those enable SME businesses to use Web servers and mail servers with their own domain easily. There are some problems in carriers' shared hosting server replacement because users want high service quality as same as network services and many users use same hosting services. Only a short time server down is allowed, customer IP addresses must be same and sufficient announcement and preparation time for users are needed. In this paper, we explain the key points of server replacement project such as data migration tool development, user announcement and migration work scheduling to reduce user impacts.

There are many levels of customer requirements for system architecture design. There is only a few description related to the non-functional requirements in the RFP (Request for proposal) or customer requirements specification. As it is not necessarily the case that, all field requirements is included in the RFP or customer requirements specification, we must effort to draw out customer's true needs. In addition, project manager's wealth of experiences is necessary for the proposal of estimated specifications satisfied both customer budget and construction period. If there are insufficiency act of digging up field requirements needs or examination omission at the system architecture design, defects at operation test or high-load performance test may be actualized in lowest process. At the worst case, such situations may be caused postpone of commercial operation or rework of system construction. It is said that 80 percentages of right or wrong of project is decided at the time of estimation or contract. Investigation after receiving RFP is too late for the proposal of efficient and precise estimation minimizing the risks of non-conforming in system operation or deficiency in performance and reliability. It is important that we are prepare in advance standard examination contents of estimation as various templates which incorporate the project's historical data and expert's know-how, and visualize estimated artifact's development effort of assumed artifacts. In this paper, we propose the estimation method of system architecture design using standard estimation templates and validate the effectiveness.

In recent years, the severity of environments surrounding system development projects is steadily increasing, such as diversification of customer needs, technological diversity, short development duration, and decrease in market price. To make a project successful in such environments, it is essential not only to foster an excellent project manager, but also to create a project plan as a success story. Carrying out estimation in the project planning stage leads to the improvement of quality of the estimate, to the prevention of the discrepancy in scope recognition, and finally to the success of the project. In this paper, we introduce various measures we have taken in the development fields based on the idea above, and describe the effectiveness of the measures.
