Service coding framework
A service provider has to deal with complex business processes which may seem simple to the customers. This implies that service description should encompass the overall system from consumers to providers.We establish a framework that can describe the overall service system, based on various coding methods, including mathematical models, agent systems, service blueprints, and system dynamics. Once the overall service system is well coded, we are able to make predictions and simulations to improve the overall service system. 備考
Development of a video tool for behavior observation research
(1) Develop a video tool for observing office work. The tool is characterized by the use of video. It enables comparative study between similar or consecutive tasks, by pair-wise replaying of video clips, which are cut out and paired based on the analysis of PC screens used by the worker subjects. (2) Conduct trials in business offices. Workshops are held with both observers and subjects attending. The difficulty with the use of video recording, “There are no opportunities to ask the worker subjects a question at the time of recording” is mitigated through collaborative watching of video clips in the workshop, because it helps the subjects recall the exact situations and the reasons for their actions at that time. (3) Model the way of office working. Data will be gathered from the statistical analysis of the video clips. 備考
Identifying and implementing key drivers of successful sharing
(1) Examine sharing services. “Sharing” is a new, emerging economy from all-consuming to collaborative consumption, e.g., sharing, bartering, trading, renting, swapping. (2) Identify key drivers of successful sharing. People’s social nature, e.g., “mottainai”, “willing to help others”, “want to be recognized”, could be the answer. (3) Develop key service technologies for sharing services through supporting the key drivers. 備考
Where does the Customer Value of Sharing Service come from?
The behavior of customers has changed from all-consumption to collaborative consumption in the past decade. Sharing service is now becoming a major trend in our daily lives. From the view of customers, it has both benefits and risks: it offers benefits such as money saving and environmental protection, but it also has non-negligible risks, such as a risk of stumbling into crime in a worst-case situation. Therefore, it would make sense for human beings not to choose sharing service, since human beings are risk averse by nature. But why do people recently choose sharing service? In this paper, we present a hypothesis to answer this question. We conjecture that “a successful service provider always covers its sharing risks that otherwise must be covered by the customers.” Thus the customers of the sharing service could coop the benefits of sharing solely and this explains the recent rise of sharing service popularization. 備考
Research on Social Value Creation in Cases of Social Innovation
We plan to conduct research on social value creation, focusing on social innovation, social enterprises and social entrepreneurs. We will start a hypothesis that social values are created by making use of “temperature” difference between BOP (base of the pyramid) and developed countries
Research on Non-Economical values in Islamic Culture
We plan to conduct research on non-economic values under the influence of Islamic Culture. We will start to examine the Islamic banking system. It refers to a banking system that is based on the principles of Islamic law and guided by Islamic economics, whereby interest (riba) is prohibited.
