Dear Viju,
BPO industry or otherwise, employee training is conducted to (a) attain certain standard or (b) remain at certain level of standard.
Therefore, training efforts or training budget would vary depending on (c) nature of the industry (d) size of the company (e) complexity of the systems and processes (f) standards that company wishes to achieve (g) the direct and indirect costs that company wishes to optimise through training (h) knowledge assets that company has developed over a period of time and above all (i) what kind of learning culture the company has.
Employee training is a medium and not an end. Employee training is a ladder. It needs to have sufficient steps so as to scale the desirable height. Sometime the ladder is too short and sometimes too big. Choosing the right step ladder is a matter of leadership!
To satisfy your query further, call me on my mobile. I will propose you something that will help culture of learning. In such culture In such culture, employees self-learn rather than wait for the company to train them!
Thanks,
Dinesh Divekar
