In this study, we propose a methodology for designing a Cause-Related Marketing (CRM) strategy using Wants Chain Analysis (WCA). To delineate the methodology, the authors introduce the concept of WCA to design CRM through a concrete and effective process in a standardized manner. The methodology can help create new types of concepts of CRM that are not only donation-based but also make relationships and supply substance or service. The authors validate the efficacy of a WCA-based CRM by conducting experiments during workshops held for value co-creation, in which various CRM stakeholders participated to create concrete designs for CRM.

This chapter proposes application of framework of system design of a special zone for reconstruction of Fukushima Prefecture which suffered serious damages from the Great East Japan Earthquake, tsunami and nuclear accident at the Fukushima Daiichi Nuclear Power Plant. The framework of system design used in this chapter is called the Interactive Social Design Model (ISDM). The ISDM is useful for aggregating stakeholders' requirements and values through the process of the interactive and bottom-up communication with stakeholders, and derivation of the optimal policy in quantitative approach. In this chapter, the optimal policy designed by the ISDM for the purpose of reconstruction of Fuku-shima is compared with the existing system of the special zones for reconstruction, in which local governments which suffered from the earthquake can choose support measures from the catalogue of policy measures designed by the central government of Japan.

As satellite technology has been highly advanced, it has become difficult to assure dependability of satellite systems. Currently, dependability of satellite systems is mainly supported by various risk analysis and verification. However, sometimes it is not clear why such analysis and verification result are required for dependability of the satellite systems. In particular for development of micro satellites, due to time and cost constraints, management of risk analysis and verification has been done in ad-hoc manner. This paper presents a strategic development of a micro satellite using assurance cases. Assurance case is a documented body of evidence that provides a convincing and valid argument that a system is adequately dependable for a given application in a given environment. In Europe, assurance cases are widely used as regulation in safety- critical areas such as defense, avionics, rails, etc. In this paper, we take "Discharge and Charge system of Hodoyoshi-3 microsatellite" as an example. We conduct a writing experiment of assurance cases for the system and report how the assurance cases are used for quality assurance of the system.

This paper evaluates the effects of component reuse by using a model that focuses on information transfer in software development projects. The cost models from earlier studies do not account for the difficulty of reuse, whereas the proposed information-centric model does consider the level of this difficulty. This paper has two main conclusions. First, component reuse does not always improve the productivity of a software development project. Second, component reuse is a valuable productivity tool if the following conditions are satisfied: (1) reuse results in simplification of project structures and (2) the level of difficulty of project elements is decreased from the reuse of components.
