Various companies must select an innovation model according to their respective strategies to realize a Hyper Smart Society (HSS). Four strategic approaches exist: resources, positioning, gaming, and learning; these respectively correspond to the linear, Klein, hypothesis-testing, and interactive innovation models. Using the Stage Gate method for the linear and Klein models, enables a concentration of the appropriate themes and management resources. In doing so, the issues to be overcome, which include selecting themes and developing human resources, can be surmounted by limiting the gatekeeper to one person or applying the Boost Gate method. Conversely, a method similar to the agile method, which involves quickly repeating a short cycle of analysis, design, implementation, and testing, is considered effective with the hypothesis-testing and interactive models.
