Grant Thornton, a UK professional services firm, embarked on an ambitious cultural change initiative called "Ambition 2015" to shift its culture and grow revenues. The head of talent development, Mel Wombwell, led workshops and programs to help employees transition from solely task-focused work to building deeper client relationships. By asking open-ended questions of clients and showing vulnerability, employees found they could better understand clients and win new business. While cultural change is ongoing, Grant Thornton has already seen phenomenal success through shifting behaviors and beliefs across the organization.
