Sustainable vitality is one of the core tasks of future cities in Finland. A successful city must be attractive and appealing. All sectors of the city organisation are responsible for building vitality. But frankly, only a fraction of this new vitality is result of actions by the city itself. Vitality is becoming more depended on the activities of other community actors such as businesses, educational institutions and civil society. The current economic development organisation model is no longer the best possible way for the future. The report contains a proposal for a new organisation model, as well as the main content areas. In addition, the report contains suggestions for organising more extensive participation and development forums to be held in Jyväskylä. Vibrant Jyväskylä study was made in the autumn of 2016 and carried out by MDI’s Senior Advisor Eero Holstila. The city makes decision based on the study in the spring 2017.
