The problem (theme) proposed by Toshiba and Shimizu Corp was to propose an idea for an "active" feedback system for the community (Appendix-1). The purpose of this report is to show how Team 8 came up with a unique solution that met our sponsor's demand, "Bee Box system", to the problem proposed through the use of tools taught during ALPS.
We began from interviewing the proposer as to what he was looking for. From the hearing, we determined some keywords of what the proposer was expecting:
-Not passive unlike the currently existing system/service, but something that is active.
-Houses talking to/sensing each other within the community.
Then, we came up with a vague concept of the system through brainstorming and mind mapping (Appendix 1) based on the keywords, including the ALPS theme "Safety and Security". Next, in order to clarify/narrow down our idea, we created a CVCA (Appendix 2) to find out the stakeholders, followed by scenariographing (Appendix 3) to visualize the activity of the key stakeholder.
From the result of the above tools, we created interview questions to interview the key stakeholders (Appendix 4).
Although the interview result varied among single/married, metropolitan/suburb, a common answer was a "higher demand for mental safeness".
To visualize the demand of the Voice of Customers (Appendix 5), we used QFD I to figure out what kind of components are required to meet the demand (Appendix 6), then used QFD II to create specification of the system (Appendix 7) and to conduct
Cost Worth Analysis to be used for prioritizing component (Appendix 8). The information obtained from Cost Worth Analysis also became a factor used for conducting financial analysis (Appendix 9) to create the business model of the system (Appendix 10).
During the course of the workshop, we created several prototypes (Fig. 9 and Fig. 10). Prototyping was useful for the following reasons:
- Commonize team members understanding of the system.
- Physically present sponsor, audience, and customer, what our system looks like.
- Find out weaknesses and/or area for further consideration.
Also, through the comments achieved from the presentation, we also considered non-emergency mode of the system to make the system more attractive for the customers.
