Ah, Sales Enablement. In my opinion, one of the MOST important pieces of a launch.
I have no shortage of tips, but for the sake of time, I'll keep it to four...
1. Align with sales leadership early on your enablement plans and make sure they're a part of the planning process. This will help ensure that key things that reps need to know are detailed in your plan that you may have originally missed
2. ROLE. BASED. ENABLEMENT. What your AEs need to know about a launch is different from Sales Engineers and different from your Success teams. They each need to know different things to successfully take a product to market - lean into this. As part of your plan, you should do detailed role-based enablement for each team to ensure that the key actions each role needs to take are covered. For instance, deep pitch practice for AEs, objection handling, etc. But for your Sales Engineers a stronger focus on product capabilities, roadmap, and demo practice
3. USE YOUR SALES LEADERSHIP! Let's be real, we've all heard "why is this marketer telling me about how to sell something when they've never done it" -- To get ahead of this, bring sales leaders and well-respected reps into your enablement sessions. Have them deliver the pitch, have them do an objection handling example, have them walk through an early customer story. This will help a ton and help build trust and excitement around the launch
4. Customer examples!!! You can explain your new launch all day. You can explain the value props all day. You can talk for days about it. But nothing makes a launch real like an example from a beta customer. Share their use-case with your reps. It's so much easier for them to go out and repeat that story than it is to relay your value props.
Hope these are helpful :)
