1. Lighten the administrative load on your employees. The fewer formal structures there are, the more work is done in an informal and ongoing way. People learn when doing things this way. Take advantage of thinking outside the box and loosen up the firm structure.
2. Get rid of the idea of the concept of career ladder. Nowadays climbing walls and Tetris-style paths are the modern way of thinking. Constantly working on development, varying tasks and challenges are the bulk of careers today. Not a ladder, but a cluster of lateral opportunities and in-the-moment tasks.
