Radical Candor: Be a Kick-Ass Boss Without Losing Your Humanity is a business leadership book written by former Apple and Google executive Kim Malone Scott. In the book, Scott defines the term radical candor as feedback that incorporates both praise and criticism. Unlike radical transparency or radical honesty, Scott says the management principle of radical candor involves “caring personally while challenging directly.” The book was first published in 2017 by St. Martin's Press. A fully revised and updated version was released in 2019. Source: Wikipedia (en)
