1.1 Lab Preparation Considerations and Caveats It is in your best interests to ensure the demo environment you will be demonstrating is clean & tidy before you begin. For this reason we would recommend, where possible, you log in to your demo at least 15 minutes prior to delivery and check the following; 1. Familiarize yourself with the environment during this time and check any specific features you are expecting to demo. 2. Most importantly, be crystal clear with yourself on what it is you plan to show. A full demo of every feature described below (with questions) can take several hours. If you only have a short time slot be sure to focus on the key points that address the customer s pain points and will drive value home to them. 3. Ensure that you have scheduled the demo for sufficient time so as not to have the demo end before you are finished with the customer. Any other guidance on how the user should prepare for the lab can be added here. If there are limitation or something the user should be aware of call out also. 4 Dell Demo Center https://demos.dell.com Dell Inc., 2016
