SPIDER aims to deliver innovation in public services by putting citizens at the heart of the development process using service design. Service design is above all a problem-solving process that places the user at the centre of the methodology. By engaging both service users and service providers in developing and testing solutions. the new services are citizen-focused. desirable to use and inclusive. They are also cost effective for public authorities because the solutions correspond to user needs so avoid costly changes following failed implementation. Service design is well established in the private sector but only a limited number of public services examples exist. First. through pilots SPIDER will demonstrate how service design can be translated into cost savings and efficiencies in the public sector. Second. through large scale training and awareness raising. SPIDER will change the mindset in public authorities in their approach to understanding the needs of service users. The SPIDER partnership has chosen to collaborate on three particularly costly issues for public authorities: WP1 DRIVING AN ACTIVE YOUTH WORKFORCE. WP2 EXTENDING INDEPENDENT LIVING FOR OLDER PEOPLE and WP3 ENCOURAGING CULTURAL CHANGE WITHIN PUBLIC AUTHORITIES. To demonstrate that service design is a process that can be applied to a broad range of public services. SPIDER will test the methodology in 11 pilots to generate evidence of the impact on users and the cost savings for public authorities across different public services. Each WP will first be tested in one region before the lessons of implementation are transferred to other regions to strengthen delivery in the second phase. To embed service design. training will be delivered to 500 public service managers to enable them to employ the tools. replicate approaches and integrate them into mainstream practices. SPIDER will improve the delivery of priority frontline services making them more user-friend and cost effective.
