OAS capabilities are diverse and complex,  often adapting to the needs of its clients. This is captured in the logo by the three different shapes, each of them representing the main fields of expertise: social behaviour, fundraising and strategy. 

The circle represents the softer and more welcoming part of the business, according to the psychology of shapes in branding. In the same time, the rectangle offers a sense of reliability and security. However, the corners of the rectangle are kept rounded, to keep a softer feeling, in relashionship with the circle. The middle shape brings up the uniqueness of the brand. As a plus, the shapes, together, resemble with the symbols used very often in research.
