How would you rate your company's sales onboarding program? If you think there are a lot of improvements to be made, you're not alone. The Sales Management Association reports that following onboarding, approximately one-third of sales reps still lack proficiency in up to a dozen key selling skills. The issue isn't always that reps aren't taught these skills; the trouble is often retention and mastery of the material they learned during onboarding-which means it can be a long time until reps become field-ready.
