What are the best funding models for a Collective Action initiative?

Many Collective Action initiatives are kick-started by donor funding, but this is not a viable option for the long term. A combination of options will give you the most resilience, and may include some donor funding, membership fees or “pay as you go” models, and fees for extra services. If trust is present, and the Collective Action has clear deliverables that the stakeholders consider relevant and attainable, finding a sustainable funding model is something you can work on together with those

How do you measure the impact of a Collective Action initiative?

Measuring and reporting the impact of your work is crucial to demonstrating its value and keeping stakeholders engaged and on track. Beyond the basic stages of developing a monitoring and evaluation plan, a few points are relevant. First, transparency is crucial, to build trust and manage the expectations of both the donor and the engaged stakeholders. Second, it’s important to collect stories and testimonials that illustrate your impact, not only statistics. Third, a Collective Action approach

Corruption in public procurement – how can Collective Action help?

Engaging all stakeholders in ensuring the integrity of public procurement processes increases their chances of success. Integrity Pacts and the High Level Reporting Mechanism are forms of Collective Action that bring governments, businesses and civil society together to improve public procurement. The first step is to map out the problems and the relevant stakeholders to engage.

Can you share examples of teaching materials that cover the role of the private sector to address corruption and also more innovative approaches such as Collective Action?

Education and capacity-building are key components in the fight against corruption. Tailoring support and being responsive to the needs of different audiences is crucial in developing effective training materials on anti-corruption.

Building capacity and raising awareness about Collective Action and the role of the private sector in the fight against corruption allows for a better and common understanding of how the public and private sector and civil society can better work together to uphold

What is the business case for anti-corruption Collective Action?

Businesses face increasing pressure, from regulators, investors and civil society to conduct business responsibly. Top level company commitment to engaging in Collective Action demonstrates to law enforcement and regulatory authorities a company’s serious commitment to improving not only their internal anti-corruption programs but also making a difference in the wider business environment.

What are the benefits for Small and Medium-sized companies to engage in Collective Action?

Small and Medium-sized Enterprises (SMEs) make up the vast majority of businesses in any given economy, in the European Union for example, SMEs represent 99% of all businesses . SMEs are pivotal for economic growth and development. However, they are also more prone to corruption risks given their size and resource limitations to implement integrity and compliance programmes. On the flip side, the lack of implemented standards can hamper their capacity to access funding and participate in interna
