This change management interview question is to see if you comprehend the importance of change impact analysis. Tip 1: Emphasize the significance of measuring change. Tip 2: Describe the method of measuring the impact of a change briefly. It is not only vital but also critical. It is absurd to execute change unless the effects are quantifiable.. As a change manager, I will oversee that precise KPIs and indicators are delivered and that they are measured before, between, and once the change is implemented. The type of alteration employed will affect how I assess this impact. For example, the number of phone calls made each day, the total number of daily sales, and the number of daily customer complaints can all be utilized to assess the impact of the adjustment.
