Final answer:
The 70 in the 70-20-10 model signifies on-the-job training, focusing on learning through challenging assignments and experiences encountered in the workplace.
Step-by-step explanation:
The 70 in the 70-20-10 model for developing people represents on-the-job training. This model, created by the Center for Creative Leadership, proposes that 70% of a person's learning and development comes from challenging assignments and real-life experiences encountered during their work. This includes tackling hands-on tasks, problem-solving, and overcoming obstacles in the daily work environment.
Compared to formal education and training, on-the-job experiences are considered more impactful for professional growth since they are much more frequent and offer immediate and practical application of skills. The '70' portion of the model emphasizes that the majority of professional development occurs through these experiences, rather than through traditional classroom learning or formalized training programs.
