Is the change in line with your expectations?
Sometimes your strategies can have a different effect than originally anticipated. Where you see a change that is unexpected, you must explore it further.
If potential unintended consequences have been anticipated from the outset, there may be indicators specifically designed to see whether these consequences have emerged.
Be careful not to view the emergence of an unintended consequence as necessarily negative - some may, in fact, be positive; and even if negative, the insights they provide are valuable in re-shaping our compliance-improvement strategies.
