6Aika -Open and Smart Services is a strategy for sustainable urban development involving Finland’s largest cities, the six cities Helsinki, Espoo, Vantaa, Tampere, Turku and Oulu. The 6Aika strategy consists of three axes of cooperation: open data, open inclusion and open innovation platforms.Innovation platforms are functional entities where the urban community together generates new solutions and new business operations. Infrastructure, physical and virtual environments, productised processes and operating models, and human beings are combined into value-creating activities. The Sixth City Open Innovation Platforms project implements the objectives of the 6Aika Strategy and its Open Innovation Platforms theme. The main project’s primary purpose is to strengthen Finland’s competitiveness by combining the innovation and development environments of the major cities into a national network of open innovation platforms. The aim of the package is to create new know-how, business and jobs. Taking advantage of the diversity and specificity of operating environments in six cities, best practices, operating models and concepts for the business potential of urban solutions (Smart Market Creation) are created. The lead project utilises the best know-how in cities and the strengths of innovation that emerge from cities’ own smart specialisation choices. The contents of the lead project serve each city’s own strategically important development areas and a common goal, bringing the national open innovation platform to the special strengths of the six largest cities. The result of the operating model is a network-like and attractive national innovation platform consisting of urban innovation hubs, which supports the internationalisation of the Finnish innovation environment and the operating conditions in the digitalising world. The national network of open innovation platforms to be built in the lead project will provide companies, research organisations and other target groups with an action-driven development environment for products, solutions and services based on the “one-stop shop” principle. The aim is to facilitate companies’ field of operations in the municipal sector as a developer of Smart City solutions, to implement market dialogue with companies as part of the normal functioning of municipalities, and to support export companies and invest-in activities by providing a nationally significant reference platform for the six largest cities. At the same time, the operating model of cities will be changed from a service provider to an enabler of innovative services. Open Innovation Platforms (Open Innovation Platforms) aims to promote and enable a new creative economy and solutions based on digital processes and services that support the shift away from nature-consuming use of non-renewable resources, for example by reducing the need for mobility. A large proportion of new innovations are expected to aim at a more sustainable use of natural resources. The transition to digitalisation will reduce inequalities by equalising environments and situations. Exploiting open innovation platforms gives everyone the same opportunities to participate in, for example, service and product design. The needs and different starting points of different user groups are taken into account by means of service design. The project will develop, in cooperation with cities six, permanent structures and operating models to promote the sharing of good practices, which will be integrated into the normal functioning of cities. The focus is on close cooperation between six cities and agreed operating models that allow the scalability and benefits of solutions to multiply.
