Because it is more effective than traditional methods, and this infographic by Oneproductions explains it very well.

Let’s start from the current situation:

• the employee forgets 65% of the teaching material 7 days only after the course in the classroom, and the figure rises to 90% after six months.
• 40% of the employees who receive poor training at work leave their place within the first year.
• eLearning increases the retention rate of 25-60% and requires between 40% and 60% less time.
• 42% of companies say that eLearning has resulted in an increase of revenue and in a 18% increase in employee engagement.

The graphic illustrates the main benefits of eLearning (Always and Everywhere, Adaptable to different learning styles, Provides insight) and enumerates the features to create effective training videos for your workers.
