NEW YORK; Dec. 4, 2014 – The vast majority of corporate sales representatives are consistently average performers but could boost the competitiveness of companies by generating hundreds of millions of dollars in additional revenue each year for those businesses able to lift their performance even modestly, according to new research from Accenture (NYSE: ACN) and CSO Insights. Today, mediocre performance is costing companies 3.2 percent in potential revenue, but that could be secured through a five percent improvement in sales performance enabled by a combination of enhanced training, technology-enabled sales tools and better use of data and analytics.
