Dear Nainesh,
There is no standard as such. Allocation of hours for training will vary from one industry to another and one company to another. Suppose company is going for say ISO or Six Sigma etc, then you need to train the whole operations staffs and other supporting staffs.
However, in many companies general time budget is 2-3 working days per person per year. Again there lies a catch. In these days of "lean manpower", it is quite difficult for Ops Managers to spare his/her staff for training. Secondly, when it comes to "learning", managers are very good at delegation. But then if the training is happening at some five star resort or hotel, the same managers spring their "great learning attitude".
Therefore, in some company rather than adopting bureaucratic approach of "number of hours per year", "operations needs" derive the training requirement. When we are clear about what needs to increased or decreased, obviously number of training hours do not matter.
Ok...
