One of the biggest mistakes made by business organizations in terms of internal leadership development is to leave the task of grooming the potential leaders till the very last. However, the consultants from the leading ICF accredited executive coaching firm In Canada, strictly advice against following such an approach. This is because lack of proper grooming, makes the potential leaders ill-prepared to take on the challenges of their new roles and responsibilities in an efficient manner. This makes it extremely difficult for them to provide the expected results, which in turn can make them feel frustrated. Presuming that the future leaders will start providing immediate results simply based on their potential and without any preparedness can cost an organization dearly.
