As companies employ a workforce, one of the expectations that they have is for the employee to possess certain abilities and knowledge. Although technical concepts can be learnt or acquired from various sources including college, the internet and so on, it is still important for the companies to make sure that each of their employees has the optimum potential for better productivity. To hone their knowledge, the companies usually offer in-house training programmes besides the training they get during probation. But certain technicalities cannot be disseminated through this way.
