2020 is not far away. Given the extensive amount of work that must happen between now and then, if you don’t start now, you won’t finish. The resources of the notified body and lead times will not be available. The closer to the 2020 date, the longer we’d expect the lead times to be…if you can even get the support. At the minimum, you must execute your plan and understand how big of a gap you have to fill between now and then. At least then you’ll know if your products are in good shape with only minor tweaks to make. Hitting that date will be impossible if the plan isn’t started today.
