Sales Teams: Forum on analyzing performance based on stats

This company has 11 reps (a – k on the graph) and like every sales team, there is a wide variety of skills, effort and personalities. So here are the questions:

• Who would you consider the top rep
• Who is the worst rep
• Who would you cut and why?
• What individual training would you suggest
• What group training would you suggest
• Any comments on lead to closing ratios
• Which rep should be the bench mark for success based on their activity. 

These reports were pulled from Front Row Solutions CRM and are based on a 12 month window.  The assumption is that all the reps have been employed continuously the past 12 months.

 I look forward to your insights!
