Given the rapidly changing competencies required in technology and market influences that make talent harder to find, how does an organization shape its workforce to not only be able to deliver its current offerings but become resilient enough to deliver the offerings of the future? By focusing on business outcomes like improved time-to-readiness, better engagement and higher retention, ThoughtWorks redesigned its global onboarding program using modern research into how people learn. This experience talks about how to incrementally and iteratively improve the onboarding experience for employees, given challenges of global scale, a legacy approach and the ever-changing set of competencies and roles. Topics include competency-building strategies, spaced and just-in-time learning, mentoring, flipped classroom and transactional vs. relational onboarding.
