40under40 is an action learning based development journey delivered on a mobile device. It focuses on the completion of the 70% component of the 70-20-10 model of development, which is on-the-job learning. In this program the action learning part of the IDP is broken down into interesting actions delivered in a micro/byte size-format through the mobile app. These actions are tracked through the IDP tracker by the learner’s manager also via the Mobile App, ensuring high adherence to the program. 40under40 can be customized to a company’s competency framework or can complement the existing leadership training initiatives, workshops or e-learning programs (which largely focuses on the 10% of the 70-20-10 model).
