In the question below, are given a statement followed by three courses of actions numbered I, II and III. On the basis of the information given, you have to assume everything in the statement to be true, and then decide which of the suggested course of action logically follow (s) for pursuing. Statement: Talent management is a term that includes activities such as recruiting, sustaining, developing/progressing and rewarding the talent acquired using the most trusted practices. Gradually, modern-day entrepreneurs understand the ever-increasing importance of talent management practices as this can set the stage for earning high dividend in the long run. In fact, the startups or the well-established firms that fail to acknowledge the potential of aligning its key business strategies with that of its talent management schemes, often find themselves in great trouble down the road. It not just leads to huge wastage of precious resources of the organisation but also make it a fit case for failure in multiple ways.  Courses of action: I. Identifying the organisation’s true purpose and aligning the talent management strategy with it.  II. Letting the channels of communication be open and working effectively for all the employees alike.  III. Analysing huge volume of data with due care and efficiency so as to drive in losses through the masterminds who reside in-house.
