The market size of Internet portals has been continuously expanded and also competition has been fierce. For the business success of Internet portals, it is necessary to repeatedly perform a renewal project which improves their services, reflecting more improved or changed strategies. Accordingly, this paper proposes an analysis methodology for performing the renewal project more systematically and effectively. The methodology consists of four phases : establishing improved strategies, analyzing customers, deriving service alternatives, and determining services. The methodology places an emphasis on reflecting effectively customers' standpoints (i.e. customers' needs) and service providers' standpoints (i.e. business strategy) upon service improvement. Furthermore, the methodology includes a specific technique for analyzing the feasibility of services. To demonstrate the practical usefulness of the methodology, a real-life case is illustrated.

The monopropellant hydrazine thrusters are widely used for the satellite on-board propulsion system fulfilling various missions in space. They have outstanding features caused by the nearly unlimited restart capability and the very high credibility. The sole monopropellant thruster used at precent in nation is MRE-1 that is a standard component of NASA. It can produce 4.45 N of nominal thrust. Due to the glowing complexity with a satellite mission, the needs for thrusters of the diverse performance are being increased. The numerical simulation could give useful information to develop a new type thruster instead of the experiments performed previously. Therefore it is critical to make a reliable computer code to prepare design change of a thruster. In this paper, the performance analysis and validation of the satellite monopropellant hydrazine thruster currently used is accomplished as the preliminary study to serve valuable data for future design change.
