I've written before about the business benefits of using social internally within a business.

Benefits such as:-

1. Sales forecast that is 95% accurate.

2. Getting salespeople to contribute 2 months earlier.

3. A 25% uplift in worker productivity.

4. Speeding up the contribution made by returners. 

5. Tracking the contribution that sales people and SDRs make.

While some of those are "difficult to measure", obviously getting 25% more staff for free isn't difficult to measure.  But the business benefits of using social over email are and could be life changing for your business.

If you want to know more, contact me on social.
