At its core, Collective Action is a simple yet powerful concept: tackling corruption challenges together, rather than alone. Over the past two decades, anti-corruption Collective Action has grown from a niche idea to a recognised approach embedded in international standards, national strategies and corporate practices.

In the last decade, companies around the globe have significantly invested in the development of anti-corruption compliance programmes. Assessing the effectiveness of these programmes has proven challenging and requires that companies go beyond a box-checking approach, set clear objectives, measure progress and impact and foster a culture of integrity.
