The most successful sales organizations are the ones working systematically. To do that you have to have clearly defined goals, KPIs, and relentlessly measure and monitor how your sales and marketing efforts contribute to help you reach them.
This is why performance sales development teams have well thought out KPIs that are being tracked daily, weekly and monthly.
With modern technology, the question is not what you can measure, but what you benefit from measuring. Following the right metrics will help you as a sales executive evaluate the performance of your team and steer them in the right future direction. Measuring the wrong or additional metrics will simply take precious time away from the things that matter.
