Can you do good without being a "do-gooder"? INSEAD strategy professor Jasjit Singh argues that you don't need to quit your job and join an NGO to have a beneficial impact on the world. But doing the most good may not mean painting houses in your off-hours or running marathons for charity. Increasingly, businesses are pursuing both social impact and profits -- sometimes in the same sweet spot, other times through strategic trade-offs. Even if you work for a massive organisation, there are ways to make a tangible difference. Moreover, there is a persuasive, data-driven business case for doing so.
