What behavioral changes need to be encouraged within the sales team to improve their product knowledge and sales techniques?
Sellers are coin operated by nature. They have to deliver $$$ to the business to be successful. I'm hesitant to say you want to change their behavior. I think a better way to say this is you need to align product knowledge and sales technique to their objective: hitting quota.
How do you do that?
Showcase account teams that are seeing success with deep product knowledge or a specific sales technique. I like videos most for these to really communicate the process and impact.
Make it easier to use your materials. Shorter, more compelling content. Always ask how an asset could be shorter.
Bring in outside experts from the sales community who can do coaching from a sellers perspective. Sellers sometimes struggle with taking selling advice from people that haven't sold before.
