The project has following objectives:
1. To build up and sustain a stakeholder community (the SCOOP4C community) that will discuss and share experiences of once-only principle implementations for citizens (OOP4C) (and to some extent businesses), and that will bring forward issues of concern as well as key enablers for OOP4C implementations;
2. To identify, collect and share existing good practices of once-only implementations for citizens across Europe and to establish a body of knowledge about the cases, including getting an understanding of currently existing concepts, approaches and solutions;
3. To discuss challenges, needs and benefits of widely implementing and diffusing the once-only principle in co-creation and co-production contexts involving citizens and governments as data producers and data consumers;
4. To draw conclusions from comparing existing best practices with needs and challenges, including policy recommendations towards a necessary paradigm change in the public sector and of the citizens to build up trust on data shared among governments while no longer bothering citizens to repeatedly provide the same data in public service provisioning;
5. To identify relevant stakeholders and to develop a strategic stakeholder engagement plan to ensure sustainable implementations of the once-only principle with a large engagement of stakeholders in various co-creative and co-productive public service provisioning contexts;
6. To develop a tangible roadmap of future areas of actions to implement, diffuse and sustain concepts and implementations of once-only solutions for citizens.
