We're not one for cliches, but "use it or lose it" applies very well here. Research suggests that up to 50% of learning is lost within 1 month and 90% within 1 year without meaningful focus and practice.
The question we ask you is: "What portion of your team's overall role are you willing to let them forget?" "What part of that leadership development retreat are you going to allow yourself to forget?"
We've witnessed and trained thousands of people, learning from both their lack of follow through and the pitfalls of not immediately implementing the learnings. As such, the ongoing practice and engagement with those we work with long beyond the classroom day is critical for all to SHINE.
