The SLO model was first formalised in 2011 by Thomson and Boutilier. This model is designed to measure the level of acceptance of a company by the local communities, ranging from the legitimacy of benefits to institutionalised trust.
At the outset, the model was exclusively used in the mining industry. Since then, it has gradually climbed out of that rut, making its mark in other sectors where the activities of the companies concerned are also seen to meet with controversy.
This rising popularity is easily explained, as obtaining an SLO is essential to reduce the risk of public criticism, social conflict, and, in general, damage to a company’s integrity, financial health and reputation.
