From the article: 

"At the end of the day, sales enablement tools arm your sales team with the content, guidance and training they need to effectively communicate and close buying customers. This includes tools for salesperson training, coaching, content development, communications and customer engagement, coupled with performance analytics reporting designed to best optimize the sales process. Sales enablement is not about your sales operations (e.g., territory management, capacity management, compensation, systems/CRM/CPQ/SPM, sales forecasting, sales reporting, contract management), which is typically managed by an entirely different sales operations team."

This article explains the primary uses of sales enablement tools.
