What sales collateral is essential for a successful feature launch?

I don't think there is ever one asset to rule the world or be the single solution. Instead, it's about understanding how the sales organization is structured so you align your GTM to the sellers' goals. For example, can you model your first call deck off of the sales methodology used across the sales organization? Can you provide a sales enablement calendar that ends with a clear CTA like "here is a templated outreach campaign to drive prospects to our product launch webinar next Tuesday."? Can you clearly articulate how your new product launch will help the sales team retire quote, faster? Can you provide clear guides, profiles, and even company names for the team to target and close their first deal?

There isn't a single asset to rule them all. Instead, it's about understanding your audience and catering to their needs. Just like launching a new product and understanding the buyer and users, you need to study your internal stakeholders. It sounds obvious, but create a sales enablement program designed for the sales team.
