Abstract
Building up trust with possible business partners is essential for value co-creation while planning and establishing a new service system. However, being trustworthy is the initial challenge for each stakeholder when it does not have any business transaction with others in the past. Being trustworthy requires(1) quality,(2) information security,(3) partners’ compliances with laws and regulations, and(4) auditability. A service management system(SMS) is a reasonable solution to grant such requirements. The article demonstrates how our management standard, NEC Global Service Management Standard(GSMS) is stipulated from on-site practices and standards; ISO/IEC 20000, ISO/IEC 27000, ISO 9000, ITIL® and COBIT®, and how an SMS can be developed with GSMS in individual organizations. The adaptability of SMS has been enhanced through GSMS applications, such as cloud security guides, capability assessment guides, consultation programs and human resource development programs.
