Once you have tested and refined your rollout procedures in the lab, you are ready to test them in the production environment. The pilot rollout introduces the variables of user reactions and the activity in the production network, but on a limited scale¾usually 15 to 50 users. Based on this new information, you might make adjustments to your plan and or MSMQ-based application for the final rollout. If you make extensive changes to the final rollout plan or your MSMQ-based application, consider doing a second pilot rollout.
