People have been at the receiving end till now in training and development but with technology in terms of online learning and social forums in picture, it is possible to build a group of trainers inside the organisation. There are multiple benefits of having trainers from inside the organisation in terms of cost savings, 24×7 access to trainers and bonding between employees. Of course not everything can be insourced, but with help of technology you can surely think of insourcing as a viable option.
